Abstract

The polysphinctine wasp Zatypota anomala (Holmgren, 1860), a koinobiont ecto-parasitoid of spiders in the family Dictynidae, was recorded in Italy for the first time. Populations of both the wasp and its host, Dictyna pusilla Thorell, 1856, its host preference and the interaction between the parasitoid and the spider were documented in the field and by laboratory observations.

Die zu den Polysphinctinae gehörende Schlupfwespe Zatypota anomala (Holmgren, 1860), ein koinobionter Extoparasit von Spinnen der Familie Dictynidae, wurde erstmals für Italien nachgewiesen. Es werden Populationen der Wespe und ihres Wirtes, Dictyna pusilla Thorell, 1856, die Wirtspräferenz und Interaktionen zwischen Parasitoid und Spinne aus dem Freiland und dem Labor dokumentiert.

Abstract

The results of the examination of further spider material deposited in the Agricultural Zoology Museum of Iran, Iranian Research Institute of Plant Protection (Tehran, Iran), are reported, most of them from cereal fields and fruit orchards. A total of 634 specimens were studied, out of which, 106 species belonging to 70 genera and 27 families were identified. Five species are recorded for the fauna of Iran for the first time and documented by photos: Brigittea civica (Lucas, 1850) (Dictynidae), Pardosa roscai (Roewer, 1951) (Lycosidae), Tetragnatha isidis (Simon, 1880) (Tetragnathidae), Trachyzelotes miniglossus Levy, 2009 and Zelotes tenuis (L. Koch, 1866) (both Gnaphosidae). New provincial records are provided for additional 64 species. Earlier records of Heliophaneus aeneus (Hahn, 1832) in Iran are corrected to Heliophanus flavipes (Hahn, 1832) based on the re-examination of original material. Subsequently, H. aeneus has to be removed from the Iranian Checklist.

Ergebnisse der Untersuchung weiteren Spinnenmaterials aus dem Agricultural Zoology Museum of Iran, Iranian Research Institute of Plant Protection (Tehran, Iran), werden vorgestellt, der Großteil von Getreidefeldern und Obstplantagen. Insgesamt wurden 634 Individuen aus 106 Arten, 70 Gattungen und 27 Familien bestimmt. Fünf Arten wurden erstmals für den Iran nachgewiesen und werden mithilfe von Fotos dokumentiert: Brigittea civica (Lucas, 1850) (Dictynidae), Pardosa roscai (Roewer, 1951) (Lycosidae), Tetragnatha isidis (Simon, 1880) (Tetragnathidae), Trachyzelotes miniglossus Levy, 2009 und Zelotes tenuis (L. Koch, 1866) (beide Gnaphosidae). Für weitere 64 Arten werden Neunachweise für iranische Provinzen vorgelegt. Frühere Nachweise von Heliophanus aeneus (Hahn, 1832) aus dem Iran stellten sich nach einer Untersuchung des Originalmaterials als fehlbestimmte Exemplare von Heliophanus flavipes (Hahn, 1832) heraus. H. aeneus muss dementsprechend von der iranischen Checkliste entfernt werden.

First record of myrmecophyly in the scorpion Birulatus israelensis (Scorpiones: Buthidae)

Erster Nachweis von Myrmekophilie beim Skorpion Birulatus israelensis (Scorpiones: Buthidae)

View issue in browser

Abstract

The buthid scorpion genus Birulatus Vachon, 1974 includes three species, endemic to the Levant, each from a different location in Jordan, Israel and Syria, and all described from a single specimen. Fewer than ten specimens of the genus were collected so far. Nothing is known regarding their biology and ecology. During three collecting expeditions in the summer of 2016 near Mehola in the Jordan Valley, Palestine, 31 individuals of Birulatus israelensis Lourenço, 2002 (Scorpiones: Buthidae) were collected, all found exclusively on active foraging trails of the ant species Messor ebeninus Santschi, 1927, around their nests or coming in and out of the nests. These findings suggest that Birulatus has a myrmecophilous relationship with M. ebeninus ants.

Die Skorpiongattung Birulatus Vachon, 1974 (Buthidae) enthält drei in der Levante endemische Arten, die jeweils nach einem Einzelexemplar aus Jordanien, Israel und Syrien beschrieben sind. Nicht einmal 10 Exemplare der Gattung wurden bisher gesammelt und ihre Biologie und Ökologie ist unbekannt. Bei drei Sammelexpeditionen im Sommer 2016 nahe Mehola im Jordantal, Palästina, wurden 31 Exemplare von Birulatus israelensis Lourenço, 2002 (Scorpiones: Buthidae) gesammelt, alle ausschließlich gefangen an aktiven Futterstraßen der Ameisenart Messor ebeninus Santschi, 1927 im direkten Umfeld der Nester. Diese Funde legen nahe, dass Birulatus eine myrmekophile Beziehung zu M. ebeninus hat.

Public DNA barcoding data resolve the status of the genus Arboricaria (Araneae: Gnaphosidae)

Öffentliche DNA-Barcode-Daten klären den Status der Gattung Arboricaria

View issue in browser

Abstract

An analysis of public DNA barcoding data confirms that the extraction of Arboricaria Bosmans, 2000 from the genus Micaria Westring, 1851 would require the division of Micaria into at least five (and probably more) individual genera, to restore the monophyly of Micaria sensu stricto. Such an excessive splitting of a homogenous and well-defined genus would be neither desirable nor practical, and consequently Arboricaria should be considered a subjective junior synonym of Micaria, as suggested earlier (syn. conf.).

Eine Analyse von öffentlich zugänglichen DNA-Barcode-Daten bestätigt, dass die Herauslösung von Arboricaria Bosmans, 2000 aus der Gattung Micaria Westring, 1851 eine Aufteilung von Micaria in mindestens fünf Einzelgattungen erfordern würde, um die Monophylie der Restgattung Micaria im engeren Sinne wiederherzustellen. Diese exzessive Aufteilung einer homogenen und klar definierten Gattung wäre weder wünschenswert noch praktikabel, und folglich sollte Arboricaria, wie bereits früher vorgeschlagen, als subjektives jüngeres Synonym von Micaria behandelt werden (syn. conf.).

Further records of two spider-parasitoids of the genus Polysphincta (Hymenoptera, Ichneumonidae, Ephialtini) from Central Europe, with notes on

Neue Nachweise von zwei Spinnen-Parasitoiden der Gattung Polysphincta (Hymenoptera, Ichneumonidae, Ephialtini) aus Mitteleuropa, mit Beobachtungen ihrer Wirts-Interaktionen

View issue in browser

Abstract

A polysphinctine wasp Polysphincta longa, associated with the orb web building spider Araneus angulatus, was recorded for the first time in Slovakia. Further, the congener Polysphincta tuberosa was recorded in association with a new spider host Araneus sturmi. New distribution records of Polysphincta species from the Czech and Slovak Republics are presented. The final stage larva of both, P. longa and P. tuberosa, induced a specific alteration in web architecture: the spider constructed a unique 3D tangle of silk – so called “cocoon web” – to protect the parasitoid during the pupal stage. The host range of wasps belonging to the genus Polysphincta in Europe is discussed.

Die Schlupfwespe Polysphincta longa, die mit der Radnetzspinne Araneus angulatus assoziiert ist, wurde erstmals in der Slowakei gefunden. Polysphincta tuberosa wurde erstmals an der Wirtsart Araneus sturmi nachgewiesen. Neue Vorkommen von Polysphincta-Arten in der Tschechischen Republik und der Slowakei werden präsentiert. Die Larven des letzten Stadiums von P. longa und P. tuberosa induzieren eine spezielle Veränderung der Netzarchitektur: die Spinnen bilden ein dreidimensionales ‚Kokonnetz‘ um die Puppe des Parasitoiden zu schützen. Die Wirtsspektren der Polysphincta-Arten in Europa werden diskutiert.

Dolomedes plantarius (Araneae, Pisauridae) in Belarus: records, distribution and implications for conservation

Dolomedes plantarius (Araneae, Pisauridae) in Weißrussland: Nachweise, Verbreitung und Folgerungen für ihren Schutz

View issue in browser

Abstract

Dolomedes plantarius (Clerck, 1757) is becoming another iconic species within European conservation programmes. It is commonly accepted that the densest populations of this species are situated in Western Europe and many records confirm this. At the same time Eastern European populations are often not taken into account when assessing future dynamics of species distribution due to climate change. Here we provide data about D. plantarius in Belarus, which includes both an extensive literature survey and our own records in different parts of the country. The evidence provided suggest that Belarus is currently a large refugium for the fen raft spider, which was found during the last 30 years practically everywhere where specialists were interested in its study. We suggest that involvement of international research teams in studies of D. plantarius in Belarus will ensure the most efficient population management in Europe.

Dolomedes plantarius (Clerck, 1757) wird als relevante Art in europäischen Naturschutzprogrammen zunehmend berücksichtigt. Dabei wird allgemein angenommen, dass der Schwerpunkt der Verbreitung der Art in Westeuropa liegt, was auf der Vielzahl der Nachweise von dort beruht. Die osteuropäischen Vorkommen wurden bisher meist nicht beachtet, wenn klimabedingte Verbreitungsveränderungen der Art modelliert wurden. Daten zu D. plantarius aus Weißrussland werden vorgestellt, einerseits aus intensiver Literaturarbeit und andererseits aus eigenen Nachweisen in verschiedenen Teilen des Landes. Damit wird deutlich, dass Weißrussland ein bedeutendes Reservoir für die Art darstellt. Sie wurde in den letzten 30 Jahren fast immer gefunden, wenn gezielt nach ihr gesucht wurde. Wir empfehlen dass die Vorkommen in Weißrussland in die internationale Forschung einbezogen werden, um die Schutzprogramme für die Art zu optimieren.

Abstract

Mermessus trilobatus (Emerton, 1882) is recorded for the first time in Ukraine. Ist presence represents the easternmost boundary of this species in Europe. One male was found in the glacial cirque of the mountain massif Svydivets’ in the Ukrainian Carpathians at an altitude of 1495 m. The locality is a mountain stream, the banks of which have been moderately grazed by sheep. Information on the distribution of this species in Central and Eastern Europe is given.

Mermessus trilobatus (Emerton, 1882) wird erstmals für die Ukraine nachgewiesen. Es ist der östlichste Verbreitungspunkt der Art in Europa. Ein Männchen wurde in einem Kartal des Bergmassifs Svydivets in den Ukrainischen Karpaten in 1495 m Höhe gefangen. Der Fundort ist an einem Bergbach, dessen Uferbereiche extensiv mit Schafen beweidet wurden. Die Verbreitung der Art in Mittel- und Osteuropa wird diskutiert.

The Emperor is back! Rediscovery and redescription of the holotype of Pandinus imperator (Scorpiones: Scorpionidae)

Abstract

The holotype of the Emperor Scorpion Pandinus imperator (C.L. Koch, 1841) was long believed to have been lost. In 2015, as scientists at the State Museum of Natural History in Stuttgart were digitizing its entomological collections, they rediscovered the specimen on which Koch had based his description of the scorpion in 1841.

Der Holotypus des Kaiserskorpions Pandinus imperator (C.L. Koch, 1841) galt lange Zeit als verschollen. Im Zuge der Sammlungsdigitalisierung am Staatlichen Museum für Naturkunde in Stuttgart wurde das Exemplar 2015 wiederentdeckt, das Koch für seine Beschreibung 1841 zur Verfügung stand.

Uloborus walckenaerius and Oxyopes heterophthalmus in Poland (Araneae: Uloboridae, Oxyopidae)

Uloborus walckenaerius und Oxyopes heterophthalmus in Polen (Araneae: Uloboridae, Oxyopidae)

View issue in browser

Abstract

We report the presence of Uloborus walckenaerius Latreille, 1806 and Oxyopes heterophthalmus (Latreille, 1804) in Poland. Two females and a juvenile of U. walckenaerius and a male of O. heterophthalmus were recorded in a heathland in the western part of the country, in Lower Silesia. Both species are known from similar habitats in neighbouring regions in eastern Germany (Brandenburg and Saxony). Heathlands in Poland may have great importance in maintaining populations of these two species, and some other rare invertebrates. The habitat requires management activities.

Wir weisen Uloborus walckenaerius Latreille, 1806 und Oxyopes heterophthalmus (Latreille, 1804) erstmals für Polen nach. Zwei Weibchen und ein Jungtier von U. walckenaerius und sowie ein Männchen von O. heterophthalmus wurden in Heidegebieten Westpolens/Niederschlesiens gefunden. Beide Arten sind bereits aus ähnlichen Lebensräumen im benachbarten Osten Deutschlands (Brandenburg und Sachsen) bekannt. Die Calluna-Heiden Polens spielen für den Schutz beider Arten, wie auch für andere seltene Wirbellose, eine wichtige Rolle. Für den Erhalt des Lebensraumes sind Managementmaßnahmen notwendig.

Aliens in Europe: updates on the distributions of Modisimus culicinus and Micropholcus fauroti (Araneae, Pholcidae)

Aliens in Europa: Zur Verbreitung der Zitterspinnenarten Modisimus culicinus und Micropholcus fauroti (Araneae, Pholcidae)

View issue in browser

Abstract

The pholcid spiders Modisimus culicinus (Simon, 1893) and Micropholcus fauroti (Simon, 1887) are pantropical species that have spread around the world at least several decades ago. Here we present numerous new records for both species, most of which fall into the expected latitudes, i.e. between the Tropics of Cancer and Capricorn (93% and 87% of records respectively). However, we also report the first records for M. culicinus from Central Europe (Germany and Czech Republic, >50°N) and the first European record for M. fauroti from outside of Belgium (Germany). The fact that in both species several specimens have been found at more than one locality suggests that they may already be in the stage of establishment and spreading in Europe. Finally, we present an updated identification key to the genera of Pholcidae in Europe.

Die Zitterspinnen Modisimus culicinus (Simon, 1893) und Micropholcus fauroti (Simon, 1887) sind pantropisch verbreitet und haben sich vermutlich bereits seit Jahrzehnten rund um den Globus etabliert. Wir dokumentieren zahlreiche neue Fundorte für beide Arten, die meisten davon innerhalb der erwarteten Breitengrade, d.h. zwischen dem nördlichen und südlichen Wendekreis (93% bzw. 87% aller Fundorte). Darüber hinaus dokumentiert diese Arbeit den Erstnachweis von M. culicinus für Europa (Deutschland und Tschechische Republik, >50°N) sowie den ersten Europäischen Nachweis von M. fauroti außerhalb von Belgien (Deutschland). Die Tatsache, dass von beiden Arten mehrere Individuen an mehr als einem Standort gefunden wurden legt nahe, dass sich beide Arten in Europa bereits in einer Phase der Etablierung und Verbreitung befinden. Zusätzlich wird in dieser Arbeit ein aktualisierter Bestimmungsschlüssel zu den Gattungen der Zitterspinnen in Europa vorgestellt.

Abstract

This is the first detailed contribution on the arachnid fauna from heated greenhouses in the Botanical Garden of the P.J. Šafárik University in Košice (Slovakia). Over ten years 62 spider taxa in 21 families were found. Two spiders, Mermessus trilobatus (Emerton, 1882) and Hasarius adansoni (Audouin, 1826), were recorded in Slovakia for the first time. Another interesting record was the cellar spider Hoplopholcus sp. and a new locality for the exotic spiders Coleosoma floridanum Banks, 1900 and Triaeris stenaspis Simon, 1891 was discovered. Additionally, a short survey of other arachnids (except Acari) was done. A single specimen of a provisionally identifiable palpigrade species (cf. Eukoenenia florenciae), one harvestmen species, Opilio canestrinii (Thorell, 1876), and four pseudoscorpion species were recorded. The rare pseudoscorpion species Chthonius ressli Beier, 1956 was collected for the second time in Slovakia.

Hiermit wird der erste umfangreiche Beitrag zur Spinnentierfauna des Botanischen Gartens der P.J. Šafárik Universität in Košice (Slowakei) präsentiert. Während Jehren Jahren wurden 62 Spinnentaxa aus 21 Familien nachgewiesen. Zwei Spinnenarten, Mermessus trilobatus (Emerton, 1882) und Hasarius adansoni (Audouin, 1826), werden erstmals für die Slowakei gemeldet. Weiterer bemerkenswerte Nachweise sind die Kellerspinne Hoplopholcus sp. und ein neuer Fundort der exotischen Spinnenarten Coleosoma floridanum Banks, 1900 und Triaeris stenaspis Simon, 1891. Weiterhin wurden die übrigen Spinnentiere (ohne Milben) erfasst. Ein Einzelexemplar einer nicht sicher bestimmbaren Palpigradenart (cf. Eukoenenia florenciae), eine Weberknechtart, Opilio canestrinii (Thorell, 1876) sowie vier Pseudoscorpionarten wurden gefangen. Die seltene Pseudoskorpionart Chthonius ressli Beier, 1956 wird das zweite Mal für die Slowakei gemeldet.

Abstract

The first record of the oxyopid spider Oxyopes lineatus Latreille, 1806 in Germany is presented together with information on the place of discovery, current distribution and taxonomy. Other interesting spider records from Baden-Württemberg (Germany) in the collection of the Natural History Museum Karlsruhe are presented and discussed. Runcinia grammica (C. L. Koch, 1837) and Paratrachelas maculatus (Thorell, 1875) are reported for the first time for Baden-Württemberg; a record of Thanatus arenarius L. Koch, 1872 is the first rediscovery of this species here for over 100 year. The following taxonomical changes, which were proposed by Simon but not followed in the World Spider Catalog, are confirmed: Sphasus lineatus C.L. Koch, 1837 (misidentification) and Sphasus lineatus Blackwall, 1861 (misidentification) = Oxyopes heterophthalmus (Latreille, 1804).

Der Erstnachweis der Luchsspinne Oxyopes lineatus Latreille, 1806 für Deutschland wird zusammen mit weiteren interessanten Nachweisen aus Baden-Württemberg präsentiert. Dabei stellen die Funde von Runcinia grammica (C. L. Koch, 1837) und Paratrachelas maculatus (Thorell, 1875) Erstnachweise für Baden-Württemberg dar, ein Nachweis von Thanatus arenarius L. Koch, 1872 die Wiederentdeckung der Art nach über 100 Jahren. Zu jeder Art werden Angaben zum Fundort, zur Verbreitung in Deutschland und teilweise zur Taxonomie gemacht. Folgende bereits durch Simon erfolgte aber nicht im World Spider Catalog übernommene Korrekturen werden bestätigt: Sphasus lineatus C.L. Koch, 1837 (Fehlbestimmung) und Sphasus lineatus Blackwall, 1861 (Fehlbestimmung) = Oxyopes heterophthalmus (Latreille, 1804).

In the course of several collection trips on the Spanish mainland and Mallorca, 18 species of jumping spiders were recorded, including three species discovered for the first time in the Balearic Islands: Hasarius adansoni (Audouin, 1826), Heliophanus ramosus Wesołowska, 1986 and Thyene imperialis (Rossi, 1846). In addition, the first European record of Heliophanus stylifer Simon, 1878 is corrected: it refers to a misidentified female of Heliophanus ramosus Wesołowska, 1986; accordingly, H. stylifer has to be removed from the European checklist.

Während mehrerer Exkursionen auf dem spanischen Festland und der Baleareninsel Mallorca wurden 18 Springspinnenarten nachgewiesen, darunter mit Hasarius adansoni (Audouin, 1826), Heliophanus ramosus Wesołowska 1986 und Thyene imperialis (Rossi, 1846) drei Arten erstmalig für die Balearen. Außerdem wird der europäische Erstnachweis von Heliophanus stylifer Simon, 1878 zu Heliophanus ramosus Wesołowska, 1986 korrigiert; H. stylifer muss dementsprechend von der europäischen Artenliste entfernt werden.

New records of pseudoscorpions (Arachnida: Pseudoscorpiones) associated with animals and human habitats in Slovakia and the Czech Republic

Abstract

New data on pseudoscorpions associated with animals (birds, mammals, ants and true flies) and human habitats (synanthropic species) are presented. The collecting was carried out at 35 localities in Slovakia and the Czech Republic in different periods between 1989 and 2016. Altogether 149 nests of nine bird species, one mole nest, 14 nests of three rodent species, one lagomorph nest and four combined bird-rodent nests were examined. Five families were found, of which the Chernetidae was ranked first, with eight taxa and 770 specimens. Nine taxa were extracted from bird nests, from them Neobisium carcinoides (Hermann, 1804) and Dendrochernes cyrneus (L. Koch, 1873) were recorded only in this habitat type. Five species were found in mammal nests, Neobisium sylvaticum (C.L. Koch, 1835) and Lasiochernes pilosus (Ellingsen, 1910) were present only in this habitat type. Two species were collected in combined bird-mammal nests and two taxa were phoretic. Cheiridium museorum (Leach, 1817) was recorded only in synanthropic habitats and two quite rare species Microbisium suecicum Lohmander, 1945 and Chernes vicinus (Beier, 1932) were extracted only from anthills of Formica rufibarbis Fabricius, 1793. Five species were found for the first time in anthills in Slovakia. The current paper brings the first concrete faunistic data about the species Chernes vicinus from Slovakia and the second known locality of Microbisium suecicum in Slovakia. The phoresy of Allochernes peregrinus Lohmander, 1939 on true fly was recorded for the first time in Slovakia.

Neue Funde von Pseudoskorpionen, die mit Tieren (Vögeln, Säugern, Ameisen, Fliegen) und mit anthropogenen Habitaten (synanthrope Arten) vergesellschaftet sind, werden vorgestellt. Es wurde an 35 Orten in der Slowakei und in der Tschechischen Republik in verschiedenen Zeiträumen zwischen 1989 und 2016 gesammelt. Insgesamt wurden 149 Nester von neun Vogelarten, ein Maulwurfsbau, 14 Bauten von drei Nagetierarten, ein Kaninchenbau und vier kombinierte Vogel-Nagel-Nester untersucht. Es wurden fünf Pseudoskorpionfamilien nachgewiesen, am häufigsten die Chernetidae mit acht Taxa und 770 Individuen. Neun Taxa wurden aus Vogelnestern extrahiert, Neobisium carcinoides (Hermann, 1804) und Dendrochernes cyrneus (L. Koch, 1873) wurden ausschließlich in diesem Habitat gefunden. In Säugerbauten wurden fünf Arten nachgewiesen, Neobisium sylvaticum (C.L. Koch, 1835) und Lasiochernes pilosus (Ellingsen, 1910) ausschließlich dort. Zwei Arten wurden in kombinierten Vogel-Nagel-Nestern gefangen und zwei Arten waren phoretisch. Cheiridium museorum (Leach, 1817) wurde ausschließlich im synanthropen Bereich und zwei sehr seltene Arten, Microbisium suecicum Lohmander, 1945 und Chernes vicinus (Beier, 1932), wurden aus Ameisenhügeln von Formica rufibarbis Fabricius, 1793 extrahiert. Insgesamt wurden fünf Arten erstmals in der Slowakei in Ameisenhügeln gefangen. Der vorliegende Beitrag enthält die ersten genauen Daten von Chernes vicinus und den zweiten Fundort von Microbisium suecicum in der Slowakei. Allochernes peregrinus Lohmander, 1939 wurde in der Slowakei erstmals phoretisch (an einer Fliege) erfasst.

Epigaeic invertebrate community structure in two subtropical nature reserves, Eastern Cape, South Africa: Implications for conservation management

Artenzusammensetzung epigäischer Wirbelloser in zwei subtropischen Naturschutzgebieten (Ostkap, Südafrika): Folgerungen für das Naturschutzmanagement

Abstract

Epigaeic invertebrates were sampled at non-invaded (‘Indigenous Forest’ and ‘Indigenous Grassland’) and alien-invaded (‘Eucalyptus’ and ‘Mixed Alien’) sub-sites in the Nduli and Luchaba Nature Reserves using pitfall traps. A total of 2054 specimens belonging to three phyla (Arthropoda, Mollusca and Annelida) was caught and sorted into seven orders, 18 families, one tribe, 45 genera (22 identified to species level) and 20 morphospecies. Higher species richness occurred in ‘Indigenous Forest’ and ‘Mixed Alien’ sub-sites while higher specimen counts were made in invaded (‘Mixed Alien’ and ‘Eucalyptus’) sub-sites during summer months, peaking in January. Canonical Correspondence Analysis results show that some measured site variables, e.g. litter depth, grazing intensity, percentage of alien vegetation cover, and soil chemical properties accounted for invertebrate taxa composition and distribution trends at sub-sites. Although habitat-patch level characteristics (including abiotic factors) were important for determining species distributions, increased levels of infestation by invasive alien vegetation across sub-sites did not necessarily impact on epigaeic invertebrates in a predictable manner. For guiding management decisions, future studies on the effects of invasive alien plants on epigaeic invertebrates should distinguish between ecological effects and adverse impacts on species of conservation concern.

Activity-density data reveal community structure of Lycosidae at a Mediterranean shrubland

Aktivitätsdichte als Einflussfaktor für die Artenzusammensetzung der Wolfspinnen (Lycosidae) in einem mediterranen Buschland

Abstract

The structure of an ecological community is shaped by diverse factors and processes, including competition for resources between species with similar ecological niches. Species coexistence in the face of competition is achieved by various mechanisms, such as niche partitioning, e.g. division of resources in space and time. We studied the effect of environmental variables on activity-density of the four lycosid species found in a Mediterranean shrubland in Israel, in the spring of 2012. We tested if spatial and temporal niche partitioning enables coexistence among the four ecologically similar lycosid spiders, using multivariate analyses (RDA, Species Response Curves and Trait Analysis (RLQ)) of vegetation structure, habitat characteristics and land use, as well as time in the season. Activity-density was significantly affected by time in the season and the interaction of time and geophyte density. These findings provide first insights into the life cycles of lycosid species in Mediterranean shrublands in Israel, with spider species of the same size-group reaching their activity peaks at different times.

Description of a new Gibbaranea (Araneae: Araneidae) from the Western Mediterranean

Beschreibung einer neuen Gibbaranea-Art aus der westlichen Mittelmeerregion (Araneae: Araneidae)

Abstract

A new humped orb-weaver, Gibbaranea bruuni Lissner spec. nov., is described from specimens collected in Majorca, Spain. The new species is most closely related to two other western Palaearctic species, Gibbaranea gibbosa (Walckenaer, 1802) and Gibbaranea occidentalis Wunderlich, 1989. Araneus dromedarius cuculliger Simon, 1909 (= Gibbaranea bituberculata cuculliger) is synonymized with Gibbaranea bituberculata (Walckenaer, 1802), syn. nov.

Eine neue Höcker-Radnetzspinne, Gibbaranea bruuni Lissner spec. nov., wird nach Exemplaren beschrieben, die auf Mallorca (Spanien) gesammelt wurden. Die neue Art ist nahe verwandt mit zwei anderen Arten der Westpaläarktis, Gibbaranea gibbosa (Walckenaer, 1802) und Gibbaranea occidentalis Wunderlich, 1989. Araneus dromedarius cuculliger Simon, 1909 (= Gibbaranea bituberculata cuculliger) wird mit Gibbaranea bituberculata (Walckenaer, 1802) synonymisiert (syn. nov.).

First records of fungi pathogenic on spiders for the Republic of Serbia

Erstnachweise von arachnophagen Pilzen für Serbien

Abstract

During an investigation into parasitic fungi on arthropods in the mixed forests of Mt. Fruška Gora, Republic of Serbia, two pathogenic species were found: Cordyceps thaxteri Mains (anamorph: Cordyceps thaxteri Mains (Anamorph: Akanthomyces aranearum (Petch) Mains) and Torrubiella arachnophila (J.R. Johnst.) Mains (Anamorph: Gibellula leiopus (Vuill. ex Maubl.) Mains (Hypocreales, Cordycipitaceae). Both specimens were found in the anamorphic (asexual) stage. Previously, there have been no investigations of this group of fungi in this region, thus these are the first records of pathogenic fungi for both Mt. Fruška Gora and the entire territory of the Republic of Serbia. Collected specimens are deposited in the Herbarium of the National Park Fruška Gora, Republic of Serbia.

Im Rahmen einer Untersuchung von Schlauchpilzen (Ascomyceten = Ascomycota), die auf Arthropoden parasitieren, wurden im Untersuchungsgebiet Fruška Gora (Vojvodina, Serbien) zwei spinnen-parasitierende Arten gefunden: Cordyceps thaxteri Mains (Anamorph: Akanthomyces aranearum (Petch) Mains) und Torrubiella arachnophila (J.R. Johnst.) Mains (Anamorph: Gibellula leiopus (Vuill. ex Maubl.) Mains (Hypocreales, Cordycipitaceae). Beide Exemplare wurden im anamorphen, ungeschlechtlichen Stadium gefunden. Bisher wurden in dieser Region keine Untersuchungen zu dieser Pilzgruppe gemacht. Die Funde sind somit Erstmeldungen für das Fruška Gora Gebirge und für Serbien. Die gesammelten Individuen sind im Herbar des Nationalparks Fruška Gora, Serbien, hinterlegt.

Web architecture alteration of the orb web weaving spider Metellina merianae (Araneae, Tetragnathidae) induced by the parasitoid Megaetaira madida (Ichneumonidae, Polysphincta group)

Durch den Parasitoid Megaetaira madida (Ichneumonidae, Polysphincta Gruppe) induzierte Veränderungen im Netzbau von Metellina merianae (Araneae, Tetragnathidae)

Abstract

The polysphinctine wasp Megaetaira madida (Haliday, 1838) is a koinobiont ecto-parasitoid of spiders of the genus Metellina. Under the influence of the parasitoid’s final instar larva, the spider host M. merianae (Scopoli, 1763) built a three-dimensional web architecture, which differed considerably from the capturing orb web. The alteration of spider web behaviour induced by a parasitoid larva in this host-parasitoid pair is described for the first time.

Die Schlupfwespe Megaetaira madida (Haliday, 1838) aus der Polysphincta-Gattungsgruppe ist ein koinobiontischer Ektoparasitoid von Spinnen der Gattung Metellina. Unter Einfluss des letzten Larvenstadiums des Parasitoiden baute die Wirtsspinne M. merianae (Scopoli, 1763) dreidimensionale Netze, deren Architektur erheblich von der der normalen Fangnetze abweicht. Die Veränderung des Netzbauverhaltens einer Spinne durch die Larve dieses Wirt-Parasitoiden-Paares wird erstmals beschrieben.

East meets West: on the true identity of Cheiracanthium rupestre and Xysticus albomaculatus (Arachnida: Araneae: Eutichuridae, Thomisidae)

Anmerkung zur wahren Identität von Cheiracanthium rupestre und Xysticus albomaculatus (Arachnida: Araneae: Eutichuridae, Thomisidae)

Abstract

Cheiracanthium rupestre Herman, 1879, and Xysticus albomaculatus Kulczyński, 1891, both originally described from Hungary, are among the most rarely reported species of their genera in Europe. Here we report that both of these species have very close relationships to similarly uncommon species originally described from France at about the same time. The specimens currently considered as Cheiracanthium rupestre turn out to be very closely related to, but distinct from, Cheiracanthium striolatum Simon, 1878. However, the original description of C. rupestre does not match these specimens nor any other known species of Cheiracanthium. We therefore consider C. rupestre a nomen dubium and suggest that all previous records of this species after the original description actually refer to Cheiracanthium macedonicum Drensky, 1921. Xysticus albomaculatus, on the other hand, turns out to be a junior synonym of Bassaniana baudueri (Simon, 1877) syn. nov., expanding the range of this species considerably to the East and at the same time confirming that it is a genuine European species, rather than a recent immigrant from North America as previously suspected.

Die beiden aus Ungarn beschriebenen Großspinnen Cheiracanthium rupestre und Xysticus albomaculatus gehören zu den seltensten Vertretern ihrer Gattungen in Europa. Es zeigt sich, dass beide Arten enge Affinitäten zu Arten haben, die etwa zur gleichen Zeit aus Frankreich zuerst beschrieben wurden. Die gemeinhin als C. rupestre bezeichneten Exemplare sind eng verwandt mit C. striolatum Simon, 1878, gehören aber zu einer eigenen Art. Da die Originalbeschreibung von C. rupestre jedoch deutliche Unterschiede zu diesen Exemplaren aufweist, und sich auch sonst keiner bekannten Cheiracanthium-Art zuordnen lässt, betrachten wir C. rupestre als nomen dubium; der gültige Name für die bisher zu dieser Art gestellten Exemplare ist Cheiracanthium macedonicum Drensky, 1921. Xysticus albomaculatus erwies sich bei näherer Untersuchung als jüngeres Synonym von Bassaniana baudueri (Simon, 1877) syn. nov., was eine deutliche Ausdehnung des Nachweisareals nach Osten darstellt und bestätigt, dass es sich bei dieser Form um eine autochthone europäische Art handelt, nicht um einen rezenten Import aus Nordamerika, wie zuvor angenommen.

Phantom spiders 2: More notes on dubious spider species from Europe

Phantomspinnen 2: Weitere Bemerkungen zu zweifelhaften Spinnenarten aus Europa

Abstract

A surprisingly large number of European spider species have never been reliably rediscovered since their first description many decades ago. Most of these are probably synonymous with other species or unidentifiable, due to insufficient descriptions or missing type material. In this second part of a series on this topic, we discuss about 100 of these cases, focusing mainly on species described in the early 20th century by Pelegrín Franganillo Balboa and Gabor von Kolosváry, as well as a number of jumping spiders and various miscellaneous species. In most cases, the species turned out to be unidentifiable nomina dubia, but for some of them new synonymies could be established as follows: Alopecosa accentuata auct., nec (Latreille, 1817) = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa barbipes oreophila Simon, 1937 = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa mariae orientalis (Kolosváry, 1934) = Alopecosa mariae (Dahl, 1908) syn. nov.; Araneus angulatus afolius (Franganillo, 1909) and Araneus angulatus atricolor Simon, 1929 = Araneus angulatus Clerck, 1757 syn. nov.; Araneus angulatus castaneus (Franganillo, 1909) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus angulatus levifolius (Franganillo, 1909), Araneus angulatus niger (Franganillo, 1918) and Araneus angulatus nitidifolius (Franganillo, 1909) = Araneus angulatus Clerck 1757 syn. nov.; Araneus angulatus pallidus (Franganillo, 1909), Araneus angulatus crucinceptus (Franganillo, 1909), Araneus angulatus fuscus (Franganillo, 1909) and Araneus angulatus iberoi (Franganillo, 1909) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus circe strandi (Kolosváry, 1935) = Araneus circe (Audouin, 1826) syn. nov.; Araneus diadematus nemorosus Simon, 1929 and Araneus diadematus soror (Simon, 1874) = Araneus diadematus Clerck, 1757 syn. nov.; Araneus pyrenaeus (Simon, 1874) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus sericinus (Roewer, 1942) = Aculepeira armida (Audouin, 1826) syn. nov.; Arctosa brevialva (Franganillo, 1913) = Arctosa villica (Lucas, 1846) syn. nov.; Arctosa cinerea (Franganillo, 1913) [nec Arctosa cinerea (Fabricius, 1777)] = Arctosa perita (Latreille, 1799) syn. nov.; Cresmatoneta eleonorae (Costa, 1883) and Cresmatoneta mutinensis orientalis (Strand, 1914) = Cresmatoneta mutinensis (Canestrini, 1868) syn. nov.; Cyclosa conica albifoliata Strand, 1907, Cyclosa conica defoliata Strand, 1907, Cyclosa conica leucomelas Strand, 1907, Cyclosa conica pyrenaica Strand, 1907, Cyclosa conica dimidiata Simon, 1929, Cyclosa conica rubricauda Simon, 1929 and Cyclosa conica triangulifera Simon, 1929 = Cyclosa conica (Pallas, 1772) syn. nov.; Dendryphantes lanipes C.L.

L. Koch, 1838) syn. nov.

Eine überraschende Anzahl von europäischen Spinnenarten wurde seit ihrer Erstbeschreibung nie wieder zuverlässig wiedergefunden. In den meisten Fällen handelt es sich vermutlich um Synonyme anderer Arten oder die Arten bleiben aufgrund von unzulänglichen Beschreibungen und verlorenem Typusmaterial unidentifizierbar. In diesem zweiten Teil einer Serie zu diesem Thema besprechen wir etwa 100 dieser Fälle, mit einem besonderen Augenmerk auf Arten, die zu Beginn des 20. Jahrhunderts von Pelegrín Franganillo Balboa und Gabor von Kolosváry beschrieben wurden. Ebenso werden einige Springspinnenarten und diverse andere Einzelfälle behandelt. In den meisten Fällen erwiesen sich die untersuchten Arten als unidentifizierbare nomina dubia, aber auch einige neue Synonymien konnten festgestellt werden.

Storage buildings and greenhouses as stepping stones for non-native, potentially invasive spiders (Araneae) – a baseline study in Basel, Switzerland

Lagerhäuser und Gewächshäuser als Trittsteine für potenziell invasive nicht-einheimische Spinnen (Araneae) – eine Bestandsaufnahme in Basel, Schweiz

Abstract

Transportation of goods via land, sea or air causes a dissemination of species on a global scale. In central Europe species that are associated with fruit, vegetables and/or buildings are suspected to be imported and potentially build up populations in the following four categories of buildings: I) greenhouses, garden centres, flower shops and flower wholesale stores, II) storage buildings and logistic centres, III) botanical gardens and zoos and IV) touristic hotspots. During this research 20 such localities in and around Basel were investigated by means of visual searching. 340 adult spider individuals were collected, representing 37 species and 15 families. Three were first records for Switzerland. Eight species were not published before for the region of Basel even if six of these were already known in private, not published collections – partly going back to the 1930s. Our investigation shows that the interpretation of the spread and invasion of species needs good published knowledge about the actual status of our fauna which, especially for synanthropic spiders, is not the case. We therefore urge everybody to publish all knowledge about faunistics even for so-called common species.

Gütertransport auf dem See-, Land- oder Luftweg verursacht die Verschleppung von Arten in einem globalen Rahmen. In Mitteleuropa können vor allem Arten, welche mit Früchten, Gemüse und/oder Gebäuden assoziiert sind, importiert werden und eventuell in den folgenden vier Kategorien von Gebäuden dauerhafte Populationen ausbilden: I) Gewächshäuser, Gartencenter und Blumenhandelsketten, II) Lagerhäuser und Logistikhäuser, III) Warmhäuser in Zoos und botanischen Gärten und IV) touristische Knotenpunkte. An 20 solchen Orten in und um Basel wurde Spinnen mit Sichtfang von Hand gesammelt. 340 adulte Spinnen verteilt auf 37 Arten aus 15 Familien wurden gefangen. Drei Arten waren Erstnachweise für die Schweiz. Acht Arten wurden erstmals für die Region Basel gemeldet, wobei sechs davon schon aus Privatsammlungen bekannt, aber nicht publiziert waren - teilweise bereits aus den Dreissigerjahren des letzten Jahrhunderts. Unsere Untersuchung zeigt, dass für die Interpretation von Invasion oder Ausbreitung von Arten gute faunistische Kenntnisse unabdingbar wären, was speziell für synanthrope Arten nicht der Fall ist. Wir empfehlen daher dringend alle faunistischen Daten, auch zu sogenannten trivialen Arten zu publizieren.

A collection of sea spiders (Pycnogonida: Pantopoda) in the National Museum, Prague (Czech Republic)

Eine Asselspinnen-Sammlung (Pycnogonida: Pantopoda) im Nationalmuseum Prag (Tschechische Republik)

Abstract

The arachnological collection of the National Museum, Prague contains material preserved in ethanol and a microscopic slide of Recent sea spiders (Pycnogonida: Pantopoda). The collection is small, containing only twelve specimens. A revision of all of them revealed the presence of nine species from five families: Anoplodactylus lentus Wilson, 1878, Boreonymphon abyssorum (Norman, 1873), Callipallene sp., Endeis spinosa (Montagu, 1808), Nymphon grossipes (Fabricius, 1780), Nymphon hirtipes Bell, 1853, Nymphon stroemi Krøyer, 1844, Nymphon tenellum (Sars, 1888) and Pycnogonum litorale (Ström, 1762). The material preserved in ethanol was collected in the North Atlantic Ocean and adjacent seas, the pycnogonid mounted on the slide was collected in Mediterranean. Four of the sea spiders came from the Sars collection (Bergen, Norway) and four specimens came from the V. Frič collection (Prague, Czech Republic). From these two sources, six specimens were mounted for exhibition and educational purposes. Although the collection contains no types, it introduces an interesting group of marine animals.

A checklist of the spiders (Araneae) of the Chornohora Mountain massif (the Ukrainian Carpathians)

Eine Checkliste der Spinnen (Araneae) des Chornohora Gebirgsmassifs (Ukrainische Karpaten)

Abstract

The present checklist of spiders native to the Chornohora Mts of the Ukrainian Carpathians is based both on literature-derived data and on material collected by the authors in 1999, 2006 and 2011-2014. The majority of these studies (approximately 80 %) were conducted in the upper montane forests, subalpine and alpine levels on the slopes of the main ridge and adjacent spurs and mountains. The study also covers glacial cirques and river valleys. A few spiders were collected from local villages. The list of spiders includes records from the collections of the Museum of Natural History of the Wroclaw University and Museum (Poland) and the Institute of Zoology, Polish Academy of Sciences, Warsaw. A total of 252 valid species from 22 families is known from the Chornohora Mt. massif.

Die vorliegende Checkliste der Spinnen des Chornohora Gebirges in den Ukrainischen Karpaten umfasst sowohl Literaturdaten als auch Aufsammlungen der Autoren in den Jahren 1999, 2006 und 2011 bis 2014. Die meisten dieser Arbeiten (ca. 80 %) wurden in montanen Wäldern sowie an den subalpinen und alpinen Hängen des Hauptkammes und der Nebenkämme durchgeführt. Weitere Daten stammen aus den Gletscherbereichen, Flusstälern und Siedlungsbereichen. Die Checkliste umfasst auch Funde der Sammlungen der Universität und des Naturkundemuseums Breslau und des Institutes für Zoologie der Polnischen Akademie für Wissenschaften in Warschau. Insgesamt werden für das Chornohora Gebirge 252 Arten aus 22 Familien dokumentiert.

Cave survey yields a new spider family record for Israel

Höhlenuntersuchungen erbringen den Neunachweis einer Spinnenfamilie für Israel

Abstract

Leptonetidae and Phyxelididae were discovered as part of the first thorough cave survey of arthropods in Israel, and are reported here for the first time from caves in Israel. Both families were found in relatively temperate and humid caves at the western part of Israel and in intermediate elevation, at the cave entrance and the twilight zone. Leptonetidae were recorded for the first time in Israel.

Catching of spiders in shallow subterranean habitats in the Czech Republic

Fang von Spinnen in oberflächennahen unterirdischen Lebensräumen in der Tschechischen Republik

Abstract

Spiders occurring in soils and fissured rocks were investigated using pipe traps. Four microphthalmic species, namely Hahnia microphthalma, Porrhomma egeria, P. microps and P. cambridgei were collected. Hahnia microphthalma is reported from the Czech Republic for the first time. The importance of collecting material by complex pipe traps (consisting of a perforated pipe and a set of removable cups) to record the depth distribution of spiders in subterranean habitats is stressed. The importance of the soil and fissure network formed by sandy marlite bedrock and of alluvial soils for the life of subterranean spiders is documented.

Further notes on spiders from the Special Nature Reserve Zasavica (Serbia)

Ergänzungen zur Spinnenfauna des Zasavica-Naturschutzgebietes (Serbien)

Abstract

Zasavica is a wetland in western central Serbia with very little information on its spider fauna. During 2011 faunistic research was carried out; the material collected mostly using pitfall traps, but also sweep netting, beating and hand-collecting. A total of 3053 individuals were caught, and 107 species from 21 families were identified. Among these species, seven are first records for the Serbian fauna: Holocnemus pluchei (Scopoli, 1763), Dactylopisthes digiticeps (Simon, 1881), Walckenaeria alticeps (Denis, 1952), Pachygnatha listeri Sundevall 1830, Liocranoeca striata (Kulczyński, 1882), Phrurolithus minimus C. L. Koch, 1839 and Tibellus maritimus (Menge, 1875). Additionally, 59 species are new for the reserve. Beside a new species list for the reserve, some notes on these national records were made.

Zasavica ist ein Feuchtgebietskomplex im westlichen Mittelserbien, zum dem bisher nur wenige arachnologische Daten vorliegen. Im Jahr 2011 wurde eine faunistische Erhebung durchgeführt, wobei die Erfassung der Spinnen mittels Barberfallen, Keschern, Klopfen und Handaufsammlungen erfolgte. Insgesamt wurden 3053 Individuen, die sich auf 107 Arten aus 21 Familien verteilten, gesammelt. Sieben Arten wurden hierbei erstmals für Serbien nachgewiesen: Holocnemus pluchei (Scopoli, 1763), Dactylopisthes digiticeps (Simon, 1881), Walckenaeria alticeps (Denis, 1952), Pachygnatha listeri Sundevall 1830, Liocranoeca striata (Kulczyński, 1882), Phrurolithus minimus C. L. Koch, 1839 und Tibellus maritimus (Menge, 1875).59 Arten sind Neufunde für Zasavica. Neben einer aktualisierten Artenliste wird die Ökologie und Verbreitung der Neufunde für Serbien näher beschrieben.

Impact of prescribed burning on a heathland inhabiting spider community

Auswirkungen von kontrolliertem Brennen auf eine Heide bewohnende Spinnengesellschaft

Abstract

Heathlands can provide refuge for many stenotopic and endangered arthropods, if habitat management practices are applied. A management measure that is rarely being used today, but which has the potential to support diversity of arthropod communities, is prescribed burning. In this study we investigated the effects of prescribed burning on spider assemblages on a burned site with Calluna vulgaris in the nature reserve Lueneburg Heath, northwest Germany. We used pitfall trapping with a sampling design of 39 traps over a period of one year and 17 sampling intervals on a burned and a control site. We compared overall species richness, activity abundance patterns and community composition of the two sites, with a particular focus on stenotopic and endangered species. We collected 5116 adult spiders and 99 species altogether in a relatively small sampling area. This number of species represents nearly one third of the regional species pool of heathland spider species. Twelve species occurred exclusively on the burned site in contrast to 28 species exclusively found on the unburned site. Although we found more than twice as many spider individuals and higher mean species richness on the control site than on the burned site, the species richness of red-listed spiders was higher on the burned site. Especially the fact that we found 24 endangered species on the burned site and only 20 on the control site indicates that the applied measure of prescribed burning can foster certain endangered spider species and contribute to preserving the overall biodiversity of heathland ecosystems.

Heidelandschaften können als Refugium für viele stenotope und gefährdete Arthropodenarten fungieren, wenn ein bestimmtes Heidemanagement angewandt wird. Eine Managementmaßnahme, die zwar heute selten praktiziert wird, obwohl sie sich positiv auf die Diversität von Arthropodengesellschaften auswirkt, ist kontrolliertes Brennen. In dieser Arbeit untersuchen wir die Auswirkungen von kontrolliertem Brennen auf eine Spinnenzönose einer mit Calluna vulgaris bestandenen Brandfläche im Naturschutzgebiet Lüneburger Heide in Nordwestdeutschland. Die Spinnen wurden in 39 Bodenfallen über einen Zeitraum von einem Jahr mit 17 Fallenleerungen auf der gebrannten und einer Kontrollfläche gefangen. Wir vergleichen die Artenvielfalt, die Individuenhäufigkeit und die Zusammensetzung der Spinnengemeinschaft der beiden Flächen miteinander. Wir fingen 5116 adulte Spinnenindividuen mit 99 Arten auf einer verhältnismäßig kleinen Probefläche. Diese Anzahl der Spinnenarten stellt fast ein Drittel des regionalen Artenpools der Heidespinnenarten dar. Wir fanden zwölf Arten ausschließlich auf der gebrannten und 28 ausschließlich auf der ungebrannten Fläche. Obwohl die durchschnittliche Artenzahl größer und die Gesamtzahl der Individuen fast doppelt so hoch auf der Kontrollfläche war, war dennoch die Artenvielfalt der gefährdeten Arten auf der gebrannten Fläche höher als auf der ungebrannten. Allein die Tatsache, dass wir insgesamt 24 gefährdete Arten auf der gebrannten Fläche und nur 20 gefährdete Arten auf der Kontrollfläche fanden, weist darauf hin, dass die angewandte Maßnahme des kontrollierten Brennens bestimmte Spinnenarten fördern und zur Erhaltung der Biodiversität der Heideökosysteme beitragen kann.

The case history of a toxic sting of a Leiurus abdullahbayrami scorpion in Turkey

Der klinische Verlauf eines giftigen Stiches des Skorpions Leiurus abdullahbayrami in der Türkei

Abstract

Scorpion stings are very common in Turkey. Nevertheless, they are not well documented in the literature and were never reported for the recently described scorpion species Leiurus abdullahbayrami Yağmur, Koç & Kunt, 2009. Here, we report a case in which a 30-year-old male was stung by a L. abdullahbayrami scorpion in the field. He was directly brought to the emergency department of the local hospital. The symptomatic process was observed and documented. In this case, no antivenom was necessary; we hypothesize that the scorpion has used most of its venom in a previous incident (explained in further detail below) and was therefore not able to inject a normal dosage.

Skorpionstiche kommen in der Türkei häufig vor. Dennoch sind sie nur wenig in der Literatur dokumentiert und es war noch kein Stich des erst vor wenigen Jahren beschriebenen Skorpions Leiurus abdullahbayrami Yağmur, Koç & Kunt, 2009 bekannt. Wir berichten über den Stich eines 30-jährigen Mannes in der freien Natur gestochen wurde und über seine medizinische Behandlung. Er wurde direkt in ein nahe gelegenes Krankenhaus gebracht. Der symptomatische Verlauf wurde beobachtet und dokumentiert; von der Verabreichung eines Gegengiftes wurde abgesehen. Wir vermuten, dass der Skorpion kurz vorher eine große Giftmenge abgegeben hat (wird im Detail erläutert) und daher nicht in der Lage war eine normale Giftmenge zu injizieren.

Spiders and harvestmen on tree trunks obtained by three sampling methods

Spinnen und Weberknechte mit drei Methoden an Baumstämmen gefangen

Abstract

We studied spiders and harvestmen on tree trunks using three sampling methods. In 2013, spider and harvestman research was conducted on the trunks of selected species of deciduous trees (linden, oak, maple) in the town of Přerov and a surrounding floodplain forest near the Bečva River in the Czech Republic. Three methods were used to collect arachnids (pitfall traps with a conservation fluid, sticky traps and cardboard pocket traps). Overall, 1862 spiders and 864 harvestmen were trapped, represented by 56 spider species belonging to 15 families and seven harvestman species belonging to one family. The most effective method for collecting spider specimens was a modified pitfall trap method, and in autumn (September to October) a cardboard band method. The results suggest a high number of spiders overwintering on the tree bark. The highest species diversity of spiders was found in pitfall traps, evaluated as the most effective method for collecting harvestmen too.

Zur Springspinnenfauna (Araneae, Salticidae) der griechischen Dodekanes-

Insel Kos, mit zwölf Erstnachweisen

On the jumping spider fauna (Araneae, Salticidae) of the Greek Dodecanese island of Kos, with 12 first records

Abstract

Twelve species of jumping spiders were recorded for the first time for the Greek Dodecanese island of Kos. Five of these species (Euophrys rufibarbis, Heliophanus equester, Menemerus taeniatus, Phlegra lineata and Pseudicius badius) are considered first records for the entire Dodecanese.

Für die griechische Dodekanes-Insel Kos konnten 12 Springspinnenarten erstmals nachgewiesen werden. Darunter sind fünf Arten (Euophrys rufibarbis, Heliophanus equester, Menemerus taeniatus, Phlegra lineata und Pseudicius badius) neu für den gesamten Bereich des Dodekanes.

On the new record of the sheet-web spider Erigonoplus foveatus comb. nov. from Slovakia, with comments on Erigonoplus simplex (Araneae: Linyphiidae)

Erstnachweis der Zwergspinne Erigonoplus foveatus comb. nov. für die Slowakei, mit Anmerkungen zu Erigonoplus simplex (Araneae: Linyphiidae)

Abstract

Mecynargus foveatus (Dahl, 1912) was recorded in the territory of Slovakia for the first time. Within two years of spider research, a single adult male was collected by beating branches of Scots pine (Pinus sylvestris) in the Borská nížina lowland. We also discovered that specimens of Erigonoplus simplex Millidge, 1979 from Bulgaria were misidentified as M. foveatus. Therefore, we suggest to consider E. simplex as a new record for Bulgaria and to exclude M. foveatus from the spider fauna of Bulgaria. A revised distribution of both species is presented and discussed. Based on the high similarity to Erigonoplus, M. foveatus is transferred to this genus as Erigonoplus foveatus (Dahl, 1912) comb. nov.

Mecynargus foveatus (Dahl, 1912) wurde erstmals in der Slowakei gefunden. Bei zweijährigen Untersuchungen wurde ein einziges Männchen erfasst, per Klopfen an Ästen der Waldkiefer (Pinus sylvestris) im Borská nížina lowland (Tiefland von Zahorie, im weiteren Sinne zum Wiener Becken gehörend). Weiterhin stellate sich heraus, dass Exemplare von Erigonoplus simplex Millidge, 1979 aus Bulgarien als M. foveatus fehlbestimmt waren. Daher betrachten wir E. simplex als neuen Nachweis für Bulgarien und M. foveatus muss für die bulgarische Fauna gestrichen werden. Die Verbreitung beider Arten wurde überarbeitet, wird als Karte präsentiert und diskutiert. Basierend auf der Ähnlichkeit mit der Gattung Erigonoplus, wird M. foveatus zu dieser Gattung als Erigonoplus foveatus (Dahl, 1912) comb. nov. gestellt.

Scientific heritage of Alexandru Roşca: publications, spider collection, described species

Der wissenschaftliche Nachlass von Alexandru Roşca: Publikatione, Spinnensammlung, beschriebene Arten

Abstract

The scientific heritage of the Romanian arachnologist Alexandru Roşca (publications, spider collection, and described species) was surveyed. For almost 40 years Alexandru Roşca studied the spiders from territories that are now parts of Romania, Ukraine, Bulgaria, and Moldova. Despite political repression, Roşca made a significant contribution to the study of the spiders of Romania and bordering countries, reflected in his 19 papers including the Ph.D. thesis. A complete list of Roşca’s papers is presented. The ‘Alexandru Roşca’ spider collection is deposited in the Grigore Antipa National Museum of Natural History (Bucharest, Romania). According to the register it includes 596 species (1526 specimens) of spiders. Part of the collection was revised by different scientists and later by the present authors.

During the period 1931–1939, Roşca described 13 spider species. To date, five species names have been synonymised. We propose that six species should be treated as nomina dubia because of their poor descriptions and lack of availability of types and/or other specimens. For two of Roşca’s species, Pardosa roscai (Roewer, 1951) and Tetragnatha reimoseri (Roşca, 1939), data and figures are presented and information on them is updated.

Notes on Olpiidae (Arachnida: Pseudoscorpiones) from Iran: description of Cardiolpium bisetosum sp. nov. and redescription of Olpium omanense

Olpiidae (Arachnida: Pseudoscorpiones) aus dem Iran: Beschreibung von Cardiolpium bisetosum sp. nov. und Olpium omanense

Abstract

Recent collections of pseudoscorpions resulted in a first record and a new species from Iran. Olpium omanense Mahnert, 1991 originally described from Oman is recorded for the first time from Iran. Three congeneric species with similar morphometric characters and trichobothrial patterns, Olpium intermedium Beier, 1959, O. lindbergi Beier, 1959 and O. omanense can be separated by the setal numbers on the posterior margin of carapace and tergite I. Also, specimens reported as Olpium lindbergi Beier, 1951 from Pakistan were probably misidentified and belong to O. omanense. The new species Cardiolpium bisetosum sp. nov. is described based on males from Markazi province, western Iran. Morphometric data given in comparison to related species.

Bei Pseudoskorpion-Erfassungen im Iran wurden ein Erstnachweis und eine neue Art gefunden. Olpium omanense Mahnert, 1991 wurde ursprünglich aus dem Oman beschrieben und kann nun zum ersten Mal im Iran nachgewiesen werden. Drei eng verwandte Arten mit ähnlichen morphometrischen Eigenschaften und Trichobothrien-Mustern, Olpium intermedium Beier, 1959, O. lindbergi Beier, 1959 und O. omanense können anhand der Anzahl der Setae am posterioren Rand des Carapax und am Tergit I unterschieden werden. Bei den Nachweisen von Olpium lindbergi Beier, 1951 aus Pakistan handelt es sich um Fehlbestimmungen – alle Individuen gehören zu O. omanense. Eine neue Art Cardiolpium bisetosum sp. nov. wird nach Männchen aus der Markazi-Provinz im Westen Irans beschrieben. Vergleichende morphometrische Daten zu verwandten Arten werden präsentiert.

Die arachnologische Sammlung (Arachnida: Araneae) des Zoologischen Museums des iranischen Forschungsinstitutes für Pflanzenschutz mit neuen Artnachweise für den Iran

Abstract

The spider collection of the Zoological Museum of the Iranian Research Institute of Plant Protection was studied during the summer of 2014. A total of 180 specimens, belonging to 25 families, 60 genera and 77 species were documented. Of these, the following nine species could be recorded from Iran for the first time: Alopecosa schmidti (Hahn, 1835), Anyphaena accentuata (Walckenaer, 1802), Crustulina sticta (O. P.-Cambridge, 1861), Enoplognatha mordax (Thorell, 1875), Ero tuberculata (De Geer, 1778), Salticus zebraneus (C. L. Koch, 1837), Pardosa aenigmatica Tongiorgi, 1966, Pardosa nebulosa (Thorell, 1872) and Tmarus piochardi (Simon, 1866). Morphological and geographical data are provided for the newly recorded species. Two species (P. aenigmatica and T. piochardi) are illustrated and a map of localities is given.

Hypselistes paludicola is a junior synonym of Trichopternoides thorelli (Araneae: Linyphiidae)

Hypselistes paludicola ist ein jüngeres Synonym von Trichopternoides thorelli (Araneae: Linyphiidae)

Abstract

Hypselistes paludicola Tullgren, 1955 was mentioned only a few times in the literature since its description. After examination of the holotype, it can be concluded that Hypselistes paludicola Tullgren, 1955 is a junior synonym of Trichopternoides thorelli (Westring, 1861) syn. nov.

Hypselistes paludicola Tullgren, 1955 wurde seit seiner Beschreibung selten in der Literatur zitiert. Die Untersuchung des Holotypus bestätigt, dass Hypselistes paludicola Tullgren, 1955 identisch ist mit Trichopternoides thorelli (Westring, 1861), syn. nov.

Distribution and life-cycle of Nelima gothica (Opiliones, Sclerosomatidae) in Danish dunes

Verbreitung und Lebenszyklus von Nelima gothica (Opiliones, Sclerosomatidae) in dänischen Dünen

Abstract

Pitfall trapping in the National Park Thy, north-western Jutland, Denmark, in 2011 and 2013 revealed 3654 specimens of the harvestman Nelima gothica. In most European countries, including Denmark, this species has been considered rare and little information is available on its biology. The species was found predominantly in the yellow dune habitat close to the North Sea coast. Here it could be either very abundant or completely absent at localities only a few kilometres apart. It also occurred in lower numbers in the grey dunes and the dune heathland, and was rare in managed grassland; it disappeared from habitats further inland. In the yellow dunes high numbers were recorded especially in rather dense Ammophila arenaria vegetation not disturbed by sand shifting. The phenology follows the typical pattern of North-European Phalangiidae and Leiobuninae: an annual life-cycle with juveniles developing through late spring and summer months, reproduction in autumn and hibernation in the egg stage. The findings suggest that N. gothica may be found all along the coastal dunes of western Denmark and possibly the Wadden Sea area, though it may only locally reach high abundances. Earlier records also included the coasts of eastern Denmark.

Mit Bodenfallen wurden im Nationalpark Thy (Nordwestjütland, Dänemark), in den Jahren 2011 und 2013 3654 Exemplare des Weberknechts Nelima gothica erfasst. In Dänemark wird die Art, wie in den meisten europäischen Ländern, als selten eingestuft und es ist bisher nur wenig über ihre Biologie bekannt. Nelima gothica wurde in hoher Abundanz in Weißdünen der Nordseeküste – insbesondere in dichtem Ammophila arenaria-Bewuchs, der nicht durch Sandumschichtung gestört wurde – gefunden, fehlte aber im selben Habitat nur wenige Kilometer entfernt. In geringerer Anzahl kam die Art in Graudünen und Dünenheiden vor und nur selten im genutzen Grünland; in weiter im Inland gelegenen Habitaten war sie nicht zu finden. Die Phänologie entspricht dem typischen Muster der nordeuropäischen Phalangiidae und Leiobuninae: ein einjähriger Lebenszyklus mit Entwicklung der Jungtiere vom späten Frühjahr bis in die Sommermonate, Fortpflanzung im Herbst und Überwinterung als Eistadium. Die Funde legen nahe, dass N. gothica überall in den Küstendünen von Westdänemark und möglicherweise in der Wattenmerrregion vorkommt, auch wenn sie nur lokal hohe Abundanzen erreicht. Frühere Nachweise liegen auch von der dänischen Ostküste vor.

Propylene glycol – a useful capture preservative for spiders for DNA barcoding

Propylenglykol eignet sich zum Fang von Spinnen für DNA-Barcoding

Abstract

The usefulness of propylene glycol as capture preservative in pitfall traps, with the aim of using the captured spiders for DNA barcoding, was tested. For this purpose a laboratory experiment on the conserving and/or denaturing effect of propylene glycol on mitochondrial DNA (COI) was set up. For the experiment 110 specimens of the common and abundant wolf spider species Pardosa lugubris were manually captured, killed and incubated from one to four weeks in either pure or watered propylene glycol or 70 % denatured ethanol. Rates of successful sequencing, following a standard protocol, did not differ between samples incubated in propylene glycol and in the more commonly used ethanol. Thus, within four weeks, propylene glycol did not significantly denaturize mitochondrial DNA. In two field studies, pitfall traps with propylene glycol captured more spiders than traps with acetic acid. The effect was significant only in one of two field trials, but then consistent at three different sites and the three dominant spider families. Based on these results and our operating experience, we recommend propylene glycol as a capture preservative for (pitfall) traps to obtain specimens for DNA barcoding identification.

Die Eignung von Propylenglykol als Fangflüssigkeit in Bodenfallen zum Fang von Spinnen für eine Identifikation durch DNA-Barcoding wurde in einem Laborexperiment zur Konservierung bzw. Denaturierung mitochondrialer DNA getestet. Für das Laborexperiment wurden 110 Individuen der häufigen und abundanten Wolfspinnenart Pardosa lugubris gefangen und in purem oder verwässertem Propylenglykol oder 70 %igem denaturierten Äthanol getötet und zwischen ein und vier Wochen erstkonserviert. Die Verwendung von Propylenglykol statt Äthanol führte in keiner Variante zu einer signifikanten Senkung der Erfolgsrate für DNA-Sequenzierung nach einem Standardprotokoll. Es fand also innerhalb von 4 Wochen keine maßgebliche Denaturierung der mitochondrialen DNA in Propylenglykol statt. In zwei Feldstudien fingen Bodenfallen mit Propylenglykol als Fangflüssigkeit mehr Spinnen als mit Essig gefüllte Bodenfallen. Der Effekt war niedrig und nur in einer der beiden Feldstudien signifikant, aber konsistent in drei Teilflächen und den drei dominanten Spinnenfamilien. Aufgrund der Resultate empfehlen wir Propylenglykol als Fangflüssigkeit in (Boden-)Fallen, wenn Belege für DNA-Barcoding beschafft werden sollen, z.B. für die Erstellung einer Referenzdatenbank oder spätere (Nach-)Bestimmung.

Pseudoscorpions (Arachnida: Pseudoscorpiones) in Strict Forest Reserves in Hesse (Germany)

Pseudoskorpione (Arachnida: Pseudoscorpiones) aus hessischen Naturwaldreservaten

Abstract

In 1990 the Federal State of Hesse (Germany) started a long-term faunistic research programme in selected Strict Forest Reserves. Here we report the results of the inventory of pseudoscorpions from seven reserves: Goldbachs- und Ziebachsrück, Hasenblick, Hohestein, Kinzigaue, Niddahänge east of Rudingshain, Schönbuche and Stirnberg. A total of 4567 specimens (315-1314 per site) belonging to 13 species (4-9 per site) were recorded using a broad spectrum of methods. The bulk of material comes from pitfall traps (83%), followed by various types of stem eclectors (16%). The structure and quality of the species assemblage in the oak-dominated flood plain forest of the Kinzigaue differs strongly from those of the remaining reserves, which are all dominated by beech. In the Kinzigaue a species-rich community (9 species) with balanced dominance structure (Shannon-Index 1.67) has been recorded. At this site, rare or moderately common species reach abundance proportions of more than 50%. Most importantly, two species with strong affinities to pristine forests, Dendrochernes cyrneus and Chernes cimicoides, were exclusively recorded from this reserve. In contrast, the beech-dominated reserves were strongly dominated by a single species, Neobisium carcinoides (59-91% of the specimens, Shannon-Index <1), and the abundance proportion of the very common species exceeded 90% in each of these areas. Temperature and altitude determine the composition of the species communities significantly. Of the recorded species, two will be categorized in the forthcoming Red Lists of pseudoscorpions of Germany and Hesse. Dendrochernes cyrneus (cat. 3 "vulnerable") reached an abundance proportion of 20% in the reserve Kinzigaue. Dinocheirus panzeri (cat. G "indeterminate risk") has been recorded in single specimens from the reserves Hasenblick, Stirnberg and Niddahänge. The preferred habitat for most of the species is the forest. Species with strong affinities to forests make up more than 95% of the specimens in all reserves except for Kinzigaue, where this proportion was 89%. Species richness and abundances were not different between the Strict Forest Reserves (management was stopped at the end of the 1980's) and the reference areas with continued forestry. However, the proportions of rare and moderately common species were higher in the Strict Reserves as compared to the reference areas.

In ausgewählten hessischen Naturwaldreservaten (NWR) werden seit 1990 zoologische Langzeituntersuchungen durchgeführt. Es werden die Ergebnisse zu den Pseudoskorpionen aus sieben hessischen NWR vorgestellt: Goldbachs- und Ziebachsrück, Hasenblick, Hohestein, Kinzigaue, Niddahänge östlich Rudingshain, Schönbuche und Stirnberg. Insgesamt wurden 4567 Individuen (315-1314 pro Gebiet) aus 13 Arten (4-9 pro Gebiet) mit einem breiten Methodenspektrum erfasst. Der Großteil des Materials stammt aus Bodenfallen (83%) und verschiedenen Typen von Stammeklektoren (16%). Die Struktur und Qualität der Artengemeinschaften unterscheidet sich sehr stark zwischen dem Stieleichen-dominierten Hartholzauwald der Kinzigaue und den Buchenwald-Naturwaldreservaten (alle übrigen Gebiete). Im NWR Kinzigaue wurde eine artenreiche Zönose (9 Arten) mit ausgeglichener Dominanzstruktur angetroffen (Shannon-Index 1,67). Seltene und mäßig häufige Arten erreichen hier Individuenanteile von mehr als 50%, vor allem aber wurden die an ursprüngliche Wälder gebundenen Arten Dendrochernes cyrneus und Chernes cimicoides ausschließlich hier festgestellt. Im Gegensatz dazu werden die Buchenwald-NWR sehr stark von Neobisium carcinoides dominiert (59-91% der Individuen, Shannon-Index <1) und der Individuenanteil sehr häufiger Arten liegt in diesen sechs Gebieten bei >90%. Temperatur und Höhenlage der Gebiete zeigen signifikanten Einfluss auf die Zusammensetzung der Artengemeinschaften. Zwei der nachgewiesenen Pseudoskorpion-Arten werden in den Roten Listen Deutschlands und Hessens (Arbeitsversion) gelistet sein. Dendrochernes cyrneus (Kat. 3 „gefährdet“) erreicht im NWR Kinzigaue einen Individuenanteil von 20%. Dinocheirus panzeri (Kat. G „Gefährdung unbekannten Ausmaßes“) wurde in Einzelexemplaren in den NWR Hasenblick, Stirnberg und Niddahänge erfasst. Die Mehrzahl der nachgewiesenen Pseudoskorpion-Arten besitzt ihren Verbreitungsschwerpunkt im Wald. Waldarten im engeren Sinne erreichen in allen Untersuchungsgebieten Individuenanteile von >95%, außer im NWR Kinzigaue, wo der Anteil bei 89% liegt. Die Ende der 1980er aus der Nutzung genommen Totalreservate unterscheiden sich von weiterhin bewirtschafteten Vergleichsflächen hinsichtlich der Arten- und Individuenzahlen kaum. Die Arten- und Individuenanteile seltener und mäßig häufiger Arten sind jedoch in den Totalreservaten deutlich höher als in den Vergleichsflächen.

Back in Europe: Quamtana spiders (Araneae: Pholcidae) in Germany

Zurück in Europa: Spinnen der Gattung Quamtana (Araneae: Pholcidae) in Deutschland

Abstract

Two undescribed species of the African pholcid spider genus Quamtana have been found in German greenhouses and plant markets since 2012. Both species seem to have established stable populations. This genus has not been previously recorded from Europe, except for a fossil specimen in Eocene amber from the Paris Basin that was tentatively assigned to Quamtana and that is estimated to date from 53 million years ago. Since the actual geographic origins of the two species (probably South and/or tropical Africa) are unknown, we do not formally describe them.

Zwei unbeschriebene Arten der afrikanischen Gattung Quamtana wurden seit 2012 in deutschen Pflanzenmärkten und Gewächshäusern gefunden. Beide Arten scheinen stabile Populationen etabliert zu haben. Abgesehen von einer Art in Bernstein aus dem Eozän des Pariser Beckens, die mit Vorbehalt in die Gattung Quamtana gestellt wurde und deren Alter auf 53 Millionen Jahre geschätzt wird, ist die Gattung bisher nicht in Europa nachgewiesen worden. Da der eigentliche geographische Ursprung der beiden Arten nicht bekannt ist (vermutlich Südafrika und/oder Afrikanische Tropenländer), werden sie hier nicht formal beschrieben.

Maro lehtineni (Araneae: Linyphiidae) – a spider species new to the fauna of Poland

Maro lehtineni (Araneae: Linyphiidae) – eine neue Spinnenart für die Fauna von Polen

Abstract

The rare linyphiid spider species Maro lehtineni Saaristo, 1971 was recorded in the Polish part of the Sudetes, in the Giant Mountains (in Polish Karkonosze). Five males were found on one of the sloping transition mires in the spring and early summer of 2011 and 2012. We provide new figures for identification of this species, and summarize and discuss data on its distribution, characteristic habitats and phenology.

Die seltene Linypiidenart Maro lehtineni Saaristo, 1971 konnte im polnischen Teil des Riesengebirges (polnisch Karkonosze) nachgewiesen werden. Fünf Männchen wurden auf einem Hangzwischenmoor gefunden. Wir veröffentlichen neue Abbildungen zur Bestimmung dieser Art und fassen die Daten über Verbreitung, bevorzugten Lebensraum und Phänologie zusammen.

Nomina dubia in the genus Theridion resulting from errors in instalment six of Carl Wilhelm Hahn’s “Monographie der Spinnen” (Araneae: Theridiidae)

Nomina dubia in der Gattung Theridion durch Fehler in Heft 6 von Hahn’s „Monographie der Spinnen“ (Araneae: Theridiidae)

Abstract

An overlooked error in the correlation of new scientific names with the spider images on plate 4 in Carl Wilhelm Hahn’s sixth instalment of his book ”Monographie der Spinnen” led to the notion that at least two of the spiders illustrated on plate 4 cannot be identified and their names are nomina dubia. Here, I draw attention to the fact that, if the names are re-aligned to the images in a meaningful way, then at least three spiders on plate 4 can be identified. Theridion rufipes sensu Hahn is a synonym of Gongylidium rufipes (Linnaeus, 1758) (syn. conf.). In particular, the previous nomen dubium Theridion tibiale Hahn, 1831 is a senior synonym of Lasaeola tristis (Hahn, 1833) (syn. nov.). Evidence is presented that the junior synonym is in prevailing usage and the senior synonym is therefore regarded as nomen oblitum.

Ein bislang übersehener Fehler in der Zuordnung der neu beschriebenen wissenschaftlichen Artnamen zu den Spinnenabbildungen auf Tafel 4 des sechsten Heftes von Carl Wilhelm Hahn’s „Monographie der Spinnen“ führte zu der Auffassung, dass zumindest zwei der Spinnen auf Tafel 4 nicht identifiziert werden können und die Artnamen Nomina dubia sind. In dieser Notiz möchte ich darauf aufmerksam machen, dass mindestens drei Spinnen auf Tafel 4 identifiziert werden können, wenn man die Zuordnung der Namen zu den Abbildungen in sinnvoller Weise neu durchführt. Theridion rufipes sensu Hahn ist ein Synonym von Gongylidium rufipes (Linnaeus, 1758) (syn. conf.). Insbesondere das bisherige nomen dubium Theridion tibiale Hahn, 1831 ist ein älteres Synonym von Lasaeola tristis (Hahn, 1833) (syn. nov.). Es werden Belege angeführt wonach das jüngere Synonym in vorherrschendem Gebrauch ist, und das ältere Synonym wird daher als nomen oblitum aufgefasst.

Die Auswirkung der Habitatheterogenität des Dubringer Moores auf die Spinnenfauna (Araneae)

Effects of habitat heterogeneity on spider assemblages (Araneae) in the Dubringer Moor

Abstract

Destruction of peat bogs by drainage, peat digging, agriculture and forestry in Central Europe represents a serious threat for the conservation of adapted species and characteristic habitat types. As a basis to form recommendations for renaturation procedures we investigated spider assemblages from different habitat types on the Dubringer Moor (Saxony, Germany). Spiders were recorded by pitfall trapping in 2012 in an Erica tetralix bog, a degenerated stage of the bog dominated by Molinia caerulea, two varieties of birch wood and four varieties of Picea abies forests. 22 of the 130 recorded spider species are endangered (Red Data Books of Germany and Saxony). Indicator species for different habitat types were found. Tyrphophilic and photohygrophilic species are characteristic for the peat bog stand as well as xerophylic spiders of dry heathlands – in the latter case caused by the more xerothermous conditions on the tops of hummocks. From the perspective of nature conservation the spruce-birch forests offer a more diverse habitat structure, photic and hygric amplitude than the spruce forest monocoenosis, resulting in a more diverse spider assemblage. Therefore, these woods could represent ’stepping stones’ for some species linking to rare Betula pubescens stands. The renaturation of the damaged bog sites should be enhanced by blocking ditches and cutting spruce, leading to reduced evaporation and re-wetting of the area

Die meisten Torfmoore sind in Mitteleuropa durch Trockenlegung, Torfabbau, Land- und Forstwirtschaft beeinträchtigt. Hierdurch sind die charakteristischen Habitattypen und viele der an die hier herrschenden Lebensbedingungen angepassten Arten gefährdet. Die Untersuchungen der Spinnenfauna des vorliegenden Projekts wurden 2012 im Dubringer Moor (Sachsen) mit Hilfe von Bodenfallen in einem Heidemoor, einem von Pfeifengras dominierten, degenerierten Heidemoorstadium, zwei Birkenwaldtypen und vier unterschiedlichen Fichtenforsten durchgeführt. Es konnten insgesamt 130 Arten nachgewiesen werden, von denen 22 nach den Roten Listen von Sachsen und Deutschland als gefährdet gelten. Für die verschiedenen Habitattypen konnten Indikatorarten gefunden werden. An Moore gebundene sowie licht- und feuchteliebende Arten sind für das Torfmoor charakteristisch, genauso wie trockenliebende Arten der Heiden – bedingt durch die trocken-warmen Bedingungen auf den Bulten. Aus Sicht des Naturschutzes bieten die Fichten-Birken-Wälder eine abwechslungsreichere Habitatstruktur mit einer breiteren Vielfalt von Licht- und Feuchteverhältnissen als die reinen Fichtenforste – resultierend in einer größeren Vielfalt der Spinnenfauna. Deshalb können diese Mischwälder für einige Arten als „Trittsteine“ zur Verbindung zwischen den seltenen Moorbirkenwäldern dienen. Die Renaturierung der geschädigten Moorstandorte könnte durch das Anstauen der Entwässerungsgräben und dem Fällen der Fichten mit einer dadurch reduzierten Wasserverdunstung gefördert werden.

Allometrie sowie Bau und Funktion der Kopulationsorgane bei der Wolfspinne Arctosa leopardus (Araneae, Lycosidae)

Allometry as well as structure and function of the copulation organs of the wolf spider Arctosa leopardus(Araneae, Lycosidae)

Abstract

The prosoma length of adult males and females of the lycosid spider Arctosa leopardus (Sundevall, 1833) varies by about 200%. By contrast, the decisive structures of the copulatory organs show allometrically constant sizes. Male and female copulatory organs are described in detail. Their mechanical co-operation in copula is discussed.

In einer Population der Wolfspinne Arctosa leopardus (Sundevall, 1833) variiert die Prosomalänge adulter Tiere bis zu 200%. Demgegenüber zeigen die kopulationsmechanisch maßgeblichen Strukturen des männlichen Pedipalpenbulbus sowie der weiblichen Epigyne ein allometrisches Verhalten mit konstanten Größenverhältnissen. Der Bau der Kopulationsorgane wird detailliert dargestellt und ihr mechanisches Zusammenwirken bei der Kopulation diskutiert.

A collection of horseshoe crabs (Chelicerata: Xiphosura) in the National Museum, Prague (Czech Republic) and a review of their immunological importance

Abstract

The zoological collection of the National Museum, Prague (NMP) contains spirit (juvenile) as well as dry (mostly adult) specimens of horseshoe crabs (Xiphosura). Living horseshoe crabs are of immunological importance due to clotting agents present in their hemolymph. Here we summarize basic data about the mechanism of the immune system of these marine animals and its use in practice – the Limulus Amebocyte Lysate test – including the laboratory assays and handling with the animals. In the NMP collection, 82 specimens (16 dry and 66 spirit) of all four currently recognised living species of horseshoe crabs are present. They were collected in Indonesia, USA and Vietnam in 1872–1998; Limulus polyphemus from the USA is the most numerous species in the NMP. The collection contains no type specimens but three historical mounted ontogenetic series are present. The largest part of the horseshoe crab collection is 55 spirit specimens from the collection of Václav Frič (1839–1916) whose preparations were intended mostly for educational purposes.

A new species of Euscorpius (Scorpiones: Euscorpiidae) from southern Bulgaria

Abstract

A new scorpion species, Euscorpius drenskii sp. nov., is described from the Western Rhodope Mts. in southern Bulgaria. It is characterized by an oligotrichous trichobothrial pattern, which shows a conspicuous loss of one trichobothrium in the external median patellar series (em = 3), also observed in E. carpathicus (Linnaeus, 1767) and the subgenus Alpiscorpius Gantenbein, Fet, Largiadèr & Scholl, 1999. Phylogenetic analysis of 16S rDNA marker sequences does not show any close relationship between these three groups, suggesting that the observed loss of a trichobothrium is an independent event.

The species of the pseudoscorpion genus Pseudoblothrus (Pseudoscorpiones: Syarinidae) in Italy (on Italian pseudoscorpions XLVIII)

Abstract

The species of the genus Pseudoblothrus Beier, 1931 from Italy are revised. Two species are present in this area: P. peyerimhoffi (Simon, 1905) (Piedmont) and P. regalini Inzaghi, 1983 (Lombardy). The following synonymy is proposed: Pseudoblothrus ellingseni (Beier, 1929) is a junior subjective synonym of P. peyerimhoffi (Simon, 1905) (syn. nov.). A key to all species of the genus Pseudoblothrus is provided.

The covering setae of ground spiders (Araneae: Gnaphosidae)

Abstract

Previous study of the setae covering the opisthosoma of ground spiders shows that the morphology of the covering setae is genus-specific. The present study pursues the description of covering setae across the whole Gnaphosidae family using SEM. A detailed morphology of the setae of ground spiders (Araneae, Gnaphosidae) is presented. The six major types of covering setae recognized among gnaphosid spiders are squamose, plumose, lanceolate, pinnate, arborate and sicate setae. Squamose setae are characteristic for Micaria lenzi and Nauhea tapa. Plumose setae are more common in ground spiders and occur in the genera Drassodes, Haplodrassus, Anagraphis, Nodocion, Zelotes and the species Berlandina caspica, Nomisia aussereri, Minosiella intermedia, Sosticus loricatus, Leptodrassus memorialis, Intruda signata, Parasyrisca caucasica, Scopoides catharius, Echemoides tofo, Zimiromus medius, Encoptarthria echemophthalma, Apodrassodes trancas, Apopyllus silvestri, Hemicloea sundevalli, Zelanda erebus, Orodrassus assimilis, Callilepis nocturna and Synaphosus turanicus. The species Matua valida, Anzacia gemmea, Hypodrassodes maoricus, Homoeothele micans and Scotophaeus blackwalli have lanceolate setae. Spiders of the genus Gnaphosa have pinnate setae. Fedotovia uzbekistanica has arborate setae. The species Cesonia bilineata, Herpyllus propinquus, Litopyllus temporarius, Aphantaulax seminigra and Kishidaia conspicua have sicate setae. Some genera, such as Drassodes and Synaphosus, have a combination of different types of setae on their opisthosoma, whereas others, like Eilica sp., Laronius erawan, Urozelotes rusticus, have no covering setae on their opisthosoma at all. This study reveals the existence of different types of covering setae and provides a set of characteristics important for the classification and phylogenetic analysis of Gnaphosidae.

Clarification of the type locality of Pandinus ulderigoi with notes on the scorpions protected by CITES (Scorpiones: Scorpionidae)

Abstract

Discoveries of new species of giant scorpion (more than 14 cm in total length) are considered extremely rare. Among the largest scorpions in the world there are some species from West Africa, very popular in the pet trade and, for this reason, protected by the Washington Convention (CITES). Besides the three well-known protected species – Pandinus imperator (C. L. Koch, 1841), Pandinopsis dictator (Pocock, 1888) and Pandinus gambiensis Pocock, 1900 – a fourth giant species, Pandinus ulderigoi Rossi, 2014, was recently described from a supposedly unknown locality in the Central African Republic. Unpublished notes, just discovered, allow clarification of the exact type locality of this species. Besides newly examined material from the type locality, representative of both sexes, allows better definition of the characters of this species including its unusual trichobothrial pattern. A fifth giant species, Pandinus roeseli (Simon, 1872), recently revalidated from Pandinus imperator, is automatically included among the protected species. In light of the vulnerable status, the similar general appearance, the possibly restricted and continuous distribution with regards to the four protected species as well as the recent import suspension of P. imperator from Ghana, P. ulderigoi should be added to the Pandinus species protected by the Washington Convention.

Stenochrus portoricensis, Zomus bagnallii and a new genus of schizomids (Schizomida: Hubbardiidae) from a greenhouse in Frankfurt am Main, Germany

Stenochrus portoricensis, Zomus bagnallii und eine neue Zwerggeißelskorpion-Gattung (Schizomida: Hubbardiidae) aus einem Gewächshaus in Frankfurt am Main, Deutschland

Abstract

A new genus of hubbardiid schizomid, Bucinozomus gen. nov. with the single species B. hortuspalmarum spec. nov., is described on basis to two male specimens found in the 'Palmengarten' greenhouse in Frankfurt am Main, Germany. It clearly differs from other known genera by having a long and conical abdominal segment IX, as well as the following combination of characters: anterodorsal margin of femur IV produced at less than a 90° angle, metapeltidium divided, and pedipalps with prominent spinose setae. It differs from Trithyreus Kraepelin, 1899 by having the pedipalp trochanter with a mesal spur, leg femur IV not slender and a pedipalp tarsus with a shorter claw (half of tarsus length). Living sympatric with this new taxon were female specimens of Stenochrus portoricensis Chamberlin, 1922 and Zomus bagnallii (Jackson, 1908).

Die neue Zwerggeißelskorpion-Gattung Bucinozomus gen. nov. (Schizomida: Hubbardiidae) mit der bisher einzigen bekannten Art B. hortuspalmarum spec. nov. wurde erstmalig anhand von zwei männlichen Individuen, welche in den Gewächshäusern des Palmengartens in Frankfurt am Main (Deutschland) gefunden wurden, beschrieben. Sie unterscheidet sich deutlich von allen anderen bisher bekannten Gattungen durch den Besitz eines langen, kegelförmigen Abdominalsegments IX, so wie durch eine Kombination folgender Merkmale: Der anterodorsale Rand des Femurs IV bildet einen Winkel unter 90° aus, das Metapeltidium ist geteilt und die Pedipalpen weisen auffällig stachelige Setae auf. Von der Gattung Trithyreus Kraepelin, 1899 lässt sich die neue Gattung anhand eines mesalen Sporns auf den Pedipalpen-Trochantern, einem insgesamt weniger schlanken Femur IV und kürzeren Klauen an den Pedipalpentarsen (Hälfte der Tarsuslänge) unterscheiden. Am Fundort kommt B. hortuspalmarum spec. nov. sympatrisch mit Weibchen von Stenochrus portoricensis Chamberlin, 1922 und Zomus bagnallii (Jackson, 1908) vor.

First record of the exotic spitting spider Scytodes fusca (Araneae, Scytodidae) in Central Europe from Germany and Slovakia

Neunachweis der exotischen Speispinne Scytodes fusca (Araneae, Scytodidae) in Mitteleuropa aus Deutschland und der Slowakei

Abstract

The spitting spider Scytodes fusca Walckenaer, 1837 is recorded for the first time in Central Europe from both Germany and Slovakia. The species was found in two localities, within the Botanical Garden in Bratislava (Slovakia), specifically from a heated greenhouse with high humidity, and the 'Tropical Islands', a tropical holiday resort in Krausnick (Germany). It seems that this Pantropical species has probably been introduced here along with imported plants. A description of diagnostic characters, as well as figures, is given.

Die Speispinne Scytodes fusca Walckenaer, 1837 konnte erstmals für Mitteleuropa in Deutschland und der Slowakei nachgewiesen werden. Die Funde stammen aus dem Botanischen Garten in Bratislava (Slowakei) sowie aus dem tropischen Freizeitbad Tropical Islands in Krausnick (Deutschland). Es wird vermutet, dass die pantropische Art durch Zierpflanzen eingeschleppt wurde. Eine Beschreibung der charakteristischen Merkmale und auch Abbildungen sind eingefügt.

Revisiting the taxonomy of the rare and tiny comb-footed spider Carniella brignolii (Araneae, Theridiidae)

Ergänzungen zur Taxonomie der seltenen Zwergkugelspinne Carniella brignolii (Araneae, Theridiidae)

Abstract

Carniella brignolii Thaler & Steinberger, 1988 was first described based on a male from Austria and still belongs to the rare, scarcely studied species. Based on material from Germany and Switzerland the hitherto unknown female now can be assigned and presented. In this context a new synonymy is also proposed: The cave-dwelling, troglomorphic C. mihaili (Georgescu, 1989) from Romania, originally established as new genus Marianana, is synonymised with C. brignolii.

Carniella brignolii Thaler & Steinberger, 1988 wurde nach einem Männchen aus Österreich erstmals beschrieben und gehört noch immer zu den seltenen und wenig untersuchten Arten. Mit rezentem Material aus Deutschland und der Schweiz kann nun das bisher unbekannte Weibchen zugeordnet und dargestellt werden. In diesem Zusammenhang wird außerdem eine neue Synonymie vorgeschlagen: Die höhlenbewohnende, troglomorphe C. mihaili (Georgescu, 1989) aus Rumänien, ursprünglich Typusart der neuen, inzwischen eingezogenen Gattung Marianana, wird mit C. brignolii synonymisiert.

Miscellaneous notes on European and African Cheiracanthium species (Araneae: Miturgidae)

Verschiedene Anmerkungen über afrikanische und europäische Cheiracanthium-Arten (Araneae: Miturgidae)

Abstract

The African species Cheiracanthium furculatum Karsch, 1879 was recognised as being introduced to Germany and is re-described and illustrated in the present study. C. tenuipes Roewer, 1961 is recognised as a junior synonym of C. africanum Lessert, 1921 (new synonymy); both subspecies of C. strasseni Strand, 1915, namely C. strasseni strasseni Strand, 1915 and C. strasseni aharonii Strand, 1915, are recognised as junior synonyms of C. mildei L. Koch, 1864 (new synonymies). Photographic images of the copulatory organs of the types of C. cretense Roewer, 1928, recently synonymised with C. mildei, are provided and discussed in the course of intraspecific variation in C. mildei. The female holotype of C. rehobothense Strand, 1915 is re-described and illustrated. Relations of C. rehobothense to other Cheiracanthium species are discussed.

Die afrikanische Dornfingerspinnenart Cheiracanthium furculatum Karsch, 1879 wurde erstmals nach Deutschland eingeschleppt. In der vorliegenden Studie wird sie wiederbeschrieben und dargestellt. C. tenuipes Roewer, 1961 wird mit C. africanum Lessert, 1921 synonymisiert (neue Synonymie); beide Unterarten von C. strasseni Strand, 1915, und zwar C. strasseni strasseni Strand, 1915 und C. strasseni aharonii Strand, 1915, werden mit C. mildei L. Koch, 1864 synonymisiert (neue Synonymien). Fotographische Abbildungen der Kopulationsorgane der Typus-Exemplare von C. cretense Roewer, 1928, welche vor kurzem mit C. mildei synonymisiert wurde, werden im Rahmen der Untersuchung der intraspezifischen Variabilität von C. mildei diskutiert. Das Holotypus-Weibchen von C. rehobothense Strand, 1915 wird wiederbeschrieben und dargestellt. Beziehungen dieser Art zu anderen Cheiracanthium-Arten werden diskutiert.

The long-lasting story of the wrong naming of Silometopus ambiguus as S. curtus (Araneae: Linyphiidae)

Die lange Geschichte der Fehlbenennung von Silometopus ambiguus als S. curtus (Araneae: Linyphiidae)

Abstract

Silometopus ambiguus (O. Pickard-Cambridge, 1905) is a species occurring in coastal habitats from north-eastern to western Europe. S. curtus (Simon, 1881), occurring in southern France and north-eastern Spain, was for a long time mixed up with S. ambiguus, even though corrections have been published very early and several times. This contribution summarizes publications on this topic, discusses doubtful records of both species and proposes corrections for the World Spider Catalog; and thus tries to avoid repetitions of the mistake in the future.

Silometopus ambiguus (O. Pickard-Cambridge, 1905) kommt in Küstenlebensräumen von Nordost- bis nach Westeuropa vor. S. curtus (Simon, 1881), die aus Südfrankreich und Nordost-Spanien bekannt ist, wurde über viele Jahrzehnte mit S. ambiguus verwechselt, obwohl Berichtigungen frühzeitig und mehrfach publiziert wurden. Dieser Beitrag stellt die Publikationen zum Thema zusammen, diskutiert fragliche Nachweise beider Arten und schlägt Korrekturen für den World Spider Catalog vor. Weitere Wiederholungen dieses Fehlers sollen so in Zukunft verhindert werden.

Sensory structures and sexual dimorphism in the harvestman Dicranopalpus ramosus (Arachnida: Opiliones)

Sinnesorgane und Sexualdimorphismus der Weberknechtart Dicranopalpus ramosus (Arachnida: Opiliones)

Abstract

A survey on sensory organs of both sexes of the harvestman Dicranopalpus ramosus classifies structure and frequency of campaniform sensilla, falciform setae, sensilla basiconica, slit sensilla, solenidia, spines, sensilla chaetica, trichomes (simple hairs) and plumose setae. Sensilla are equally distributed on the pedipalp tarsi of both males and females, but females show higher counts of campaniform and falciform setae than males. Females furthermore have about 1000 glandular plumose setae on each pedipalp, that at the same positions in males are replaced by sensilla chaetica. The walking legs of both sexes show a similar distribution of sensory organs, with females showing more sensilla basiconica at the legs I and II and more solenidia on the first pair of legs. Males have a large number of bipterate setae (about 2200 per specimen) at the metatarsi and tarsi of the third and fourth pair of legs. In females these are replaced by simple hairs. Although females show a similar (or slightly higher) number of leg sensilla than males, their density is higher due to their shorter legs. In both sexes the second pair of legs has the largest number of falciform setae, sensilla basiconica, chaetica and solenidia, followed by the legs I, III and IV. The first pair of legs has the highest density of falciform setae, sensilla basiconica and solenidia, followed by the legs II, III and IV. The genital operculum, sternites and tergites show a multitude of slit sensilla. The slit sensilla of the genital operculum and sternites are associated with insertion plaques of muscles operating the penis/ovipositor and regulating opisthosomal volume and hemolymph-pressure.

Im Rahmen einer Untersuchung der Sinnesorgane beider Geschlechter der Weberknechtart Dicranopalpus ramosus werden die Struktur und Anzahl der Kuppelsensillen (campaniform), sichelformigen Borsten (falciforme Setae), Riechkegel (Sensilla basiconica), Spaltsensillen, Solenidien (röhrenförmige Setae) und Dornen sowie der Haarsensillen (Sensilla chaetica), Trichome (einfache Haare) und federförmige Haare (plumose Setae) beschrieben. Die Pedipalpen-Tarsen der männlichen und weiblichen Tiere weisen identische Verteilungen der Sensillen auf, wobei die Weibchen mehr Kuppelsensillen und sichelförmige Borsten besitzen als die Männchen. Weiterhin konnte festgestellt werden, dass auf jedem weiblichen Pedipalpus 1000 gefiederte Drüsenhaare (glanduläre plumose Setae) vorkommen, wohingegen bei den Männchen an den gleichen Stellen Haarsensillen vorgefunden werden. Die Beine beider Geschlechter weisen eine ähnliche Verteilung der Sinnesorgane auf, wobei Weibchen mehr Riechkegel in den Beinen I und II und mehr Solenidien am ersten Beinpaar aufweisen. männliche Tiere besitzen eine große Anzahl zweiflügeliger Borsten (bipterate Setae) (insgesamt ca. 2200 pro Tier) auf den Metatarsen und Tarsen des dritten und vierten Beinpaares . An gleicher Stelle sind bei weiblichen Tieren einfache Haare vorzufinden. Weibchen besitzen eine ähnliche (oder höhere) Anzahl an Beinsensillen als Männchen. Da die Beine der weiblichen Tiere jedoch kürzer sind, stehen die Beinsensillen bei ihnen dichter. In beiden Geschlechtern weisen die zweiten Beinpaare die größte Anzahl an sichelförmigen Borsten, Riechkegeln, Haarsensillen und Solenidien auf, gefolgt von den ersten, dritten und vierten Beinpaaren. Auf den ersten Beinpaaren erreichen die sichelformigen Borsten, Riechkegel und Solenidien die höchste Dichte, gefolgt von den zweiten, dritten und vierten Beinpaaren. Das Genitaloperculum, die Sternite und Tergite weisen eine Vielzahl von Spaltsensillen auf. Die Spaltsensillen des Genitaloperculums und der Sternite sind mit Muskelansätzen verbunden. Diese Muskeln steuern Penis bzw. Ovipositor und regeln das Opisthosoma-Volumen und den Hämolymph-Druck.

On the identity of the poorly known spider species Zelotes strandi (Araneae: Gnaphosidae)

On the identity of the poorly known spider species Zelotes strandi (Araneae: Gnaphosidae)

Abstract

The taxonomic status and distribution of the poorly known gnaphosid species Zelotes strandi (Nosek, 1905) is clarified, discussed and mapped on the basis of both the holotype (a single female from Turkey) and newly collected material (males and females from Bulgaria). This species was originally described from the island of Prinkipo (= Büyükada, District of Istanbul, Turkey) and the holotype is currently housed in the Naturhistorisches Museum, Vienna. Both sexes are here diagnosed and illustrated, whereby the male is described for the first time.

Ground-living spiders in wooded habitats under human influence on an island in Finland

Ground-living spiders in wooded habitats under human influence on an island in Finland

Abstract

Spiders were collected by pitfall traps in the south-western archipelago of Finland. Wooded study habitats on a small-sized (1.2 km2) island were: 1) natural open ash grove, 2) dense mixed grove (old overgrown wooded meadow), 3) wooded aspen pasture and 4) wooded meadow, both restored ten years earlier, 5) natural wooded meadow. Highest species and family numbers were found at the natural sites (1 and 5) and the lowest in the dense grove (site 2). Linyphiidae dominated, both at species and individual level, in the groves. Lycosidae were abundant on the wooded meadows and Gnaphosidae on the wooded pasture. The highest faunal similarities were between the groves (70 % species in common) and between the wooded meadows (64 %). The lowest similarity was found between the dense grove (17 %) and the ash grove (23 %) with the aspen pasture. Ten years after clearing, sites 3 and 4 had diverse spider faunas. The fauna at site 4 resembled that on the corresponding natural site (5), thus showing restoration success. Altogether 84 species of spiders were caught. The proportion of Gnaphosidae (16 species found) is high. Most species found in the study are common in south-western Finland and many occur across the whole country. Pardosa lugubris was most dominant at three sites, P. pullata and Diplostyla concolor both at one site.

Male palp organ morphology of three species of ground spiders (Araneae, Gnaphosidae)

Abstract

A detailed morphological account of the male copulatory organs of three species of ground spiders, Sergiolus capulatus, Herpyllus propinquus and Callilepis pluto (Araneae, Gnaphosidae), is presented. The large sclerites (subtegulum, tegulum and embolus) appear to be homologous in all spiders. Sergiolus and Zelanda have a plesiomorphic palp organization. The increased complexity in the male bulb organization creates a locking mechanism that fixes the male palp position during intercourse in Callilepis, as well as in Encoptarthria, Trachyzelotes and Zelotes. The palp of Herpyllus, together with Anzacia, Drassodes and Intruda, demonstrates progressive modification of the male bulb.

Juvenile specimens and adult females were found in heated greenhouses in the Botanical Garden of the Comenius University in Bratislava, Slovakia. The main morphological characters of juveniles and adult females were studied and photographed.

Do really all wolf spiders carry spiderlings on their opisthosomas? The case of Hygrolycosa rubrofasciata (Araneae: Lycosidae)

Do really all wolf spiders carry spiderlings on their opisthosomas? The case of Hygrolycosa rubrofasciata (Araneae: Lycosidae)

Abstract

Wolf spider females are characterised by carrying cocoons attached to their spinnerets. Emerged spiderlings are carried on the females’ opisthosomas, with the exception of three Japanese lycosid species who carry spiderlings on empty cocoons. Here, the same behaviour is recorded in a European spider: the drumming wolf spider Hygrolycosa rubrofasciata. Spiderlings of this species do not try to climb on the female’s opisthosoma, even when they are adopted by a female of a species with a normal pulli-carrying behaviour. This behaviour occurs in Trechaleidae and four unrelated species of Lycosidae inhabiting wet habitats and is therefore regarded as an adaptation to the unsuitable environment.

Spider records from East Macedonia and Thrace (NE Greece)

Spinnennachweise aus Ost-Mazedonien und Thrakien (NO-Griechenland)

Abstract

The present study summarises spider records from East Macedonia and Thrace (NE Greece). Spiders were mainly collected by hand sampling and to a smaller extent by pitfall trapping during field trips in 2002, 2004, 2007, 2008 and 2009. 171 species from 23 families were sampled. Pelecopsis pavida (O. P.-Cambridge, 1872) (Linyphiidae) and Xysticus kaznakovi Utochkin, 1968 (Thomisidae) were new to the European spider fauna and ten further species, Diaea livens Simon, 1876, Heriaeus graminicola (Doleschall, 1852), Meioneta ressli Wunderlich, 1973, Oedothorax retusus (Westring, 1851), Philodromus albidus Kulczynski, 1911, Pocadicnemis pumila Keyserling, 1880, Sitticus saltator (O. P.-Cambridge, 1868), Stemonyphantes lineatus (Linnaeus, 1758), Synageles scutiger Prószynski, 1979 and Thanatus coloradensis Keyserling, 1880, could be added to the Greek fauna for the first time. 21 and 38 species were new to East Macedonia and Thrace, respectively. Based on previous work, plus the present study, the Greek spider fauna now includes 1,108 species.

Beobachtungen zur Parasitierung von Radnetzspinnen (Araneidae) durch Polysphincta rufipes (Hymenoptera: Ichneumonidae)

Observations on the parasitation of orb-weaving spiders (Araneidae) by Polysphincta rufipes (Hymenoptera: Ichneumonidae)

Abstract

We found the ichneumonid Polysphincta rufipes Gravenhorst, 1829 (tribus Polysphinctini) to be a koinobiont parasitoid of two species of araneid orb-weavers, Larinioides sclopetarius and Zygiella x-notata, in Central Europe. Some notes on the biology of P. rufipes are given, based on observations both in the field and in the laboratory. The wasps directly attack non-adult spiders sitting in the hubs of their webs. Parasitized spiders could be found from, at least, August to early December. The duration of the development of the wasp larvae, including the pupal stage, is about two months. It seems conceivable that at the end of the larval stage the larva somehow manipulates its host spider; i.e. the spider is forced to enter its retreat – a safe place where the larva can kill the host, complete its development and spin a cocoon for pupation (pupa libera).

Die epigäische Spinnenfauna (Arachnida, Araneae) in Sandrasen, Borstgrasrasen und Ruderalfluren im Naturschutzgebiet „Alter Flugplatz Karlsruhe“

The epigeic spider assemblages (Arachnida, Araneae) of dry acid grassland, mat-grass and ruderal vegetation in a nature protection area in the upper Rhine valley

Abstract

Epigeic spiders were sampled using pitfall traps during one year in an anthropogenic open site within the city of Karlsruhe (Alter Flugplatz Karlsruhe). The area, historically used as a military parade ground and airport, is protected as a Special Area of Conservation (SAC) within the Natura 2000 network of the EU and since 2010 as a German nature reserve. We were interested in the diversity, assemblage structure and distribution of spider species within the area and investigated three different plant formations: sparse grass-dominated vegetation with frequent open sand patches (sandy turf), closed grassland dominated by the mat-grass (Nardus stricta) and ruderal vegetation with blackberry bushes. 123 species were identified from these captures, including many specialists of xerothermic habitats and rare and endangered species like Alopecosa striatipes, Agroeca lusatica, Haplodrassus dalmatensis, Styloctetor romanus, Typhochrestus simoni and Xysticus striatipes as well as extremely rare species of unclassified red list status like Mysmenella jobi, Theonoe minutissima and Zora parallela. The three investigated habitat types were quite similar concerning α-diversity, while measures of β-diversity indicated a strong species turnover. By performing an ecological habitat analysis (using autecological data on spiders) essential differences between the three habitat types could not be discovered, especially not between mat-grass and sandy turf. However, analysing the guild structures showed that different ways of using habitat resources dominated in the different habitat types. For Nardus-grassland several species could be identified as indicator species. While many xero- and photophiles live in the open grassland, the stenotopic psammophiles of inland dunes in the region were not found. The ruderal area houses a mix of grassland- and forest species.

A collection of spiders (Araneae) in Albanian coastal areas

A collection of spiders (Araneae) in Albanian coastal areas

Abstract

The present study unites data from several excursions in typical Mediterranean lowland ecosystems in Albania during the years 2006 to 2009. Spiders from several different habitat types along the coast were analysed in six districts: Saranda, Fieri, Kavaja, Durrësi, Tirana and Lezha. In total 299 adult specimens were collected. They belong to 82 species, 60 genera and 22 families. Six species are new to the Albanian fauna: Aculepeira armida (Audouin, 1826), Zygiella x-notata (Clerck, 1757), Histopona torpida (C. L. Koch, 1837), Malthonica campestris (C. L. Koch, 1834), Pellenes tripunctatus (Walckenaer, 1802) and Pseudeuophrys erratica (Walckenaer, 1826). With respect to zoogeography, the spider fauna is mainly characterized by the presence of many Palaearctic species.

Chelifer longimanus Kollar, 1848: a nomen nudum corresponding to Neobisium spelaeum (Schiödte, 1847) (Pseudoscorpiones: Chelonethi: Neobisiidae)

Chelifer longimanus Kollar, 1848: a nomen nudum corresponding to Neobisium spelaeum (Schiödte, 1847) (Pseudoscorpiones: Chelonethi: Neobisiidae)

Abstract

The manuscript name Chelifer longimanus Kollar, 1848, most often cited as Obisium longimanum Kollar, was first introduced in a note by Kollar (1848) that has been overlooked in the taxonomic literature on pseudoscorpions. No description or indication has been associated with this name, which is therefore a nomen nudum. It corresponds to the valid pseudoscorpion species Neobisium spelaeum (Schiödte, 1847), having been found at one of the type localities of the latter (Postojna Cave, Slovenia). Two specimens originally identified as O. longimanum (probably by V. Kollar) are present in the collections of the Naturhistorisches Museum Wien.

Faunistic spider collections in the Museum für Naturkunde Berlin: The collection of Erich Hesse

Faunistische Spinnensammlungen im Museum für Naturkunde Berlin: Die Sammlung von Erich Hesse

Abstract

The ‘Hesse collection’ of spiders (Araneae) and harvestmen (Opiliones) in the Museum für Naturkunde Berlin is documented. Biographical notes on Erich Hesse – a former arachnid curator at the museum (1921–1940) – are provided. The ‘Hesse collection’ was actually put together by other workers, and can be broadly divided into two parts. One comes from Bielinek (= Bellinchen) on the Polish side of the Oder Valley (West Pommerania); now part of the ‘Unteres Odertal’ National Park. This Bielinek material includes notable records of Heriaeus oblongus Simon, 1918 and Gibbaranea ullrichi (Hahn, 1835). The other part of the collection comes from Colbitz-Letzlinger Heide in Saxony-Anhalt, Germany. Notable here are Pistius truncatus (Pallas, 1772) and Philodromus buchari Kubcová, 2004; the latter representing the first record of this species for Saxony-Anhalt.

Nachträge zum „Katalog der schweizerischen Spinnen“ 4. Neunachweise von 2002 bis 2011

Supplement to the "Katalog der schweizerischen Spinnen" 4. New records from 2002 to 2011

Abstract

In the ”Checklist of the spiders of Central Europe” 945 species are listed for Switzerland. During the last few years numerous species have been found which represent new records for Switzerland and that, at least partly, have already been published. This 4th appendix to the catalogue of Swiss spiders presents fourteen species recorded for the first time in Switzerland: Carniella brignolii Thaler & Steinberger, 1988, Theridion cinereum Thorell, 1875, Diplocephalus foraminifer (O. P.-Cambridge, 1875), Panamomops affinis Miller & Kratochvíl, 1939, Troxochrota scabra Kulczyński, 1894, Pardosa fulvipes (Collett, 1876), P. sphagnicola (Dahl, 1908), Hahnia microphthalma Snazell & Duffey, 1980, Archaeodictyna consecuta (O. P.-Cambridge, 1872), Brommella falcigera (Balogh, 1935), Cheiracanthium campestre Lohmander, 1944, Drassodex drescoi Hervé, Roberts & Murphy, 2009, Thanatus firmetorum Muster & Thaler, 2003 and Xysticus viduus Kulczyński, 1898. Thirteen further species are presented that were already published elsewhere. The current number of species in Switzerland is thus 972. As special curiosities, five species are presented that will not yet be entered into the checklist but nevertheless may happen to be found in human surroundings.

The sejugal furrow in camel spiders and acariform mites

The sejugal furrow in camel spiders and acariform mites

Abstract

Camel spiders (Arachnida: Solifugae) are one of the arachnid groups characterised by a prosomal dorsal shield composed of three distinct elements: the pro-, meso- and metapeltidium. These are associated respectively with prosomal appendages one to four, five, and six. What is less well known, although noted in the historical literature, is that the coxae of the 4th and 5th prosomal segments (i.e. walking legs 2 and 3) of camel spiders are also separated ventrally by a distinct membranous region, which is absent between the coxae of the other legs. We suggest that this essentially ventral division of the prosoma specifically between coxae 2 and 3 is homologous with the so-called sejugal furrow (the sejugal interval sensu van der Hammen). This division constitutes a fundamental part of the body plan in acariform mites (Arachnida: Acariformes). If homologous, this sejugal furrow could represent a further potential synapomorphy for (Solifugae + Acariformes); a relationship with increasing morphological and molecular support. Alternatively, outgroup comparison with sea spiders (Pycnogonida) and certain early Palaeozoic fossils could imply that the sejugal furrow defines an older tagma, derived from a more basal grade of organisation. In this scenario the (still) divided prosoma of acariform mites and camel spiders would be plesiomorphic. This interpretation challenges the textbook arachnid character of a peltidium (or ‘carapace’) covering an undivided prosoma.

Geography-related sub-generic diversity within the Mediterranean trapdoor

spider genus Nemesia (Araneae, Mygalomorphae, Nemesiidae)

Geography-related sub-generic diversity within the Mediterranean trapdoor

spider genus Nemesia (Araneae, Mygalomorphae, Nemesiidae)

Abstract

Three different male and female super-specific types are distinguished according to variations in the morphology of the bulb and spermathecae within the genus Nemesia Audouin, 1826. Plotting the distributions of these sexual types on a map of the Mediterranean indicates the existence of geography-related sub-generic diversity in which the Nemesia fauna of the eastern Mediterranean differs markedly from that of the western Mediterranean. While the eastern Mediterranean Nemesia fauna is highly homogeneous, the fauna of the western Mediterranean is very diverse. The eastern and western Nemesia faunae appear to overlap in the central Mediterranean. Efforts to relate the specific bulb types to the particular types of spermathecae described here were only partly successful.

Spiders in Fauna Europaea: dual use of the database

Spiders in Fauna Europaea: dual use of the database

Abstract

The history and current work of the project Fauna Europaea is outlined. The different sources used for building up the database and the efforts to keep it updated are described. Available models of national checklists are discussed and the ideal checklist is described. The double use of the database as a matrix behind the official site of Fauna Europaea – as well as a directly visible document on the website of the European Society of Arachnology – are indicated and the differences in transparency, links to literature sources, and facilities such as distribution maps and calculations of numbers of scores per species or of species per country are discussed. The future of the project is briefly outlined. The need for a European identification tool for spiders is stressed.

Behavioural analysis of web building anomalies in the orb-weaving spider Zygiella x-notata (Araneae, Araneidae)

Behavioural analysis of web building anomalies in the orb-weaving spider Zygiella x-notata (Araneae, Araneidae)

Abstract

Among animal constructions, spider’s orb webs represent regular geometrical architecture models. Their construction is the result of successive, simple and reproducible behavioural patterns, often considered as stereotyped. It has recently been shown that spider’s building behaviours vary, which can alter web regularity. The final capture spiral results from the laying of successive threads between two radii, here termed ‘spiral units’. We defined a theoretical normal web, as a web in which each turn of the final spiral should be parallel to the preceding one. Weaving of the spiral units sometimes leads to anomalies in the orb web. Anomalies were identified and analysed in the orb-weaving spider Zygiella x-notata (Clerck, 1757). From video recordings of web construction, we noted the displacements of the legs and of the abdomen of the spider. We compared the frequency of displacements, and their duration, between the construction of spiral units that produce a normal turn and ones that produce an anomalous turn. The position of the legs on the web’s threads was also analysed. Results showed that anomalies were not the consequences of a modification in activity but more likely the result of the position on the radii of the fourth leg. These results suggest that spiders use local information to build the final capture spiral.

Tests for attraction to prey and predator avoidance by chemical cues in spiders of the beech forest floor

Tests for attraction to prey and predator avoidance by chemical cues in spiders of the beech forest floor

Abstract

Spiders leave draglines, faeces and other secretions behind when traveling through their microhabitat. The presence of these secretions may unintentionally inform other animals, prey as well as predators, about a recent and possible current predation risk or food availability. For a wolf spider, other spiders including smaller conspecifics, form a substantial part of their prey, and larger wolf spiders, again including conspecifics, are potential predators. We tested two hypotheses: that large wolf spiders may locate patches of potential spider prey through the presence of silk threads and/or other secretions; and that prey spiders may use secretions from large wolf spiders to avoid patches with high predation risk. We used large (subadult or adult) Pardosa saltans to provide predator cues and mixed dwarf spiders or small (juvenile) P. saltans to provide prey cues. Subadult wolf spiders were significantly attracted to litter contaminated by dwarf spiders or small conspecifics after 6 hours but no longer after 24 hours. In contrast, neither dwarf spiders nor small P. saltans showed significant avoidance of substrate contaminated by adult P. saltans. However, small P. saltans showed different activity patterns on the two substrates. The results indicate that wolf spiders are able to increase the efficiency of foraging by searching preferentially in patches with the presence of intraguild prey. The lack of a clear patch selection response of the prey in spite of a modified activity pattern may possibly be associated with the vertical stratification of the beech litter habitat: the reduced volume of spaces in the deeper layers could make downward rather than horizontal movement a fast and safe tactic against a large predator that cannot enter these spaces.

Maintenance of polymorphism in the orb weaving spider species Agalenatea redii (Araneae, Araneidae)

Maintenance of polymorphism in the orb weaving spider species Agalenatea redii (Araneae, Araneidae)

Abstract

The maintenance of polymorphism within populations may be the consequence of several elements of species life history such as use of space, activity rhythms, predation, parasitism and reproduction. The present study focuses on the latter aspect using an orb weaving spider, Agalenatea redii, which presents five different morphs of the opisthosoma pattern in the adult stage. Over the course of four years, from 2008 to 2011, adult spiders (males, females and pairs) were observed at different sites. In 2011, we also conducted a six-week survey of a single population, observing the number of spiders of each morph and the morph of paired spiders. We collected field data on the spatial and temporal distribution of spiders based on their sex and morph. Using a distance analysis, we compared the field distribution with a simulated one in which pairs were associated at random. The results showed that although there were changes over time and space in the proportions of females of the different morphs, as well as in the proportion of the pair associations, pairing according to morphs probably occurs at random.

Spiders (Araneae) of Chernivtsi Сity (Ukraine)

Spiders (Araneae) of Chernivtsi Сity (Ukraine)

Abstract

The spider fauna of buildings and other urban habitats (city parks, green areas of industrial enterprises, and housing estates) of Chernivtsi city was surveyed. In the period 2002-2011, 212 species belonging to 26 families were recorded. Previous studies found a total of 173 species of spiders belonging to 26 families from the territories which are now included in the city limits of Chernivtsi. Currently, the total spider species list for Chernivtsi includes 260 species of 30 families, of which 125 species (21 families) were recorded both by earlier researchers and by ourselves. The most important reasons for changes in urban spider assemblages are as follows: species habitat change, introduction of alien species, and description of new species unknown in the late 19th – early 20th centuries.

Assemblages of herb-dwelling spiders (Araneae) of various steppe types in Ukraine and Central Chernozem of Russia

Assemblages of herb-dwelling spiders (Araneae) of various steppe types in Ukraine and Central Chernozem of Russia

Abstract

A total of 107 spider species from 15 families were recorded in the herbaceous vegetation of the steppe ecosystems of Ukraine and the Central Chernozem region of Russia. Araneidae, Thomisidae, Salticidae and Theridiidae were the most species-rich. The species composition depended on the steppe type; adjacent forest habitats influenced steppe fauna in the forest-steppe and northern part of the steppe natural zone. The number of generalist, forest and wetland dwelling species in the steppe vegetation showed a tendency to decrease towards the south. Dominance of herb-dwelling spiders was specific to each steppe type; no single species was found to predominate in all the steppe habitats.

Badumna longinqua nach Europa eingeschleppt (Araneae: Desidae)

Badumna longinqua introduced into Europe (Araneae: Desidae)

Abstract

A female specimen of the cribellate spider species Badumna longinqua (L. Koch, 1867) was found in a 'do-it-yourself-store' in Berlin. The species is of Australian origin and has been introduced into New Zealand, Japan, Uruguay and California. This is the first record of a representative of the family Desidae from Europe. B. longinqua lives in and around houses and is apparently capable of establishing itself in Europe.

Identity and identification of Trogulus banaticus (Opiliones: Trogulidae) –

a neglected species in the Northern Balkans

Identity and identification of Trogulus banaticus (Opiliones: Trogulidae) –

a neglected species in the Northern Balkans

Abstract

Trogulus banaticus Avram, 1971 is characterised and recorded as new for Slovenia. This species was previously mistaken for T. coriziformis C. L. Koch, 1839 and T. graecus Dahl, 1903 which were later rejected from the Slovenian fauna. T. banaticus is compared with the similar, and partly sympatric, T. tingiformis C. L. Koch, 1847 with which it has often been confused. A table of distinguishing characters for both species is provided, and the ecology of T. banaticus and its general distribution are discussed.

Die Spinnenfauna (Arachnida: Araneae) stillgelegter Abbauflächen in einem Steinbruch in Bad Deutsch-Altenburg (Österreich: Niederösterreich)

The spider fauna (Arachnida: Araneae) of abandoned sites in a quarry in Bad Deutsch-Altenburg (Austria: Lower Austria)

Abstract

The epigeic spider fauna in a partially abandoned quarry in Bad Deutsch-Altenburg/ Donau (Austria: Lower Austria) was examined. Six study sites at different stages of abandonment were sampled using pitfall traps in a period from 27 March to 29 October 2006. In total, 79 species were caught comprising 845 adult individuals from 18 families. Twenty-eight species were classified as Red list taxa according to the Red lists of the Czech Republic and/or Slovakia. The poorly-known spider species Thanatus pictus L. Koch, 1881 and Xysticus embriki Kolosváry, 1935 are presented in more detail. Comparison of the six spider assemblages in the quarry with 16 geographically adjacent spider assemblages in the area of the “Parndorfer Platte” shows a clear succession within the ruderal study sites. These begin with the most recent to the oldest site, and continue to well-managed dry grasslands, further developing to scrub grasslands and hedges, and eventually to natural forests in the region.

Notes on the distribution of Oculicosa supermirabilis (Araneae, Lycosidae)

Notes on the distribution of Oculicosa supermirabilis (Araneae, Lycosidae)

Abstract

The distribution of the poorly known Central Asian wolf-spider Oculicosa supermirabilis Zyuzin, 1993 is clarified, discussed and mapped on the basis of both original and literature-derived data. The species is currently known from the Turan Lowland between the 41st and 43rd degrees of latitude north; its distribution coincides with that of the grey-brown desert soil and lies within the geobotanical sub-zone of southern deserts. Both sexes are also illustrated and diagnosed.

Notes on the biology of the unidentified invasive harvestman Leiobunum sp. (Arachnida: Opiliones)

Notes on the biology of the unidentified invasive harvestman Leiobunum sp. (Arachnida: Opiliones)

Abstract

Since about the year 2000 an unidentified, introduced harvestman of the genus Leiobunum has been rapidly invading Europe. The published records are from the Netherlands, Germany, Austria and Switzerland. A population of Leiobunum sp. in the Netherlands was studied frequently during the day and night. Its life cycle, hunting strategy, diet and accompanying harvestman species were recorded, and mating, male-male fights and ovipositing behaviour studied, as well as the spider species preying on this Leiobunum species. Food items were collected, indicating that its food consists of a wide range of live as well as dead invertebrates including spent spider prey scavenged for at ground level. Vegetable matter like berries, as well as bird droppings were also consumed. The mating strategy is very complex. A male guards an egg depositing female and he defends her against other advancing males, resulting in male-male fights. The guarding male frequently mates. Also courtship behaviour has been observed, including nuptial feeding with a fluid, probably originating from the accessory penal glands and delivered by the male into the female’s stomotheca via sacs located on the distal part of the penis truncus. Eggs are deposited in holes and crevices of walls.

Cheiridium tetrophthalmum Daday, a new synonym of Larca lata (Hansen) (Pseudoscorpiones, Larcidae)

Abstract

Cheiridium tetrophthalmum Daday, 1889 is removed from the synonymy of Geogarypus minor (L. Koch, 1873), and treated as a junior synonym of Larca lata (Hansen, 1884). The distribution of Larca lata and Geogarypus minor is documented, and L. lata is recorded from Hungary for the first time.

Wie viele Arten von Milbenkankern (Opiliones, Cyphophthalmi) gibt es in Österreich?

How many species of mite-harvestmen (Opiliones, Cyphophthalmi) are there in Austria?

Abstract

For the last 60 years, the mite-harvestman Cyphophthalmus duricorius Joseph, 1868, a soil-dwelling sironid, has been considered to be the only representative of the opilionid suborder Cyphophthalmi in Austria. However, novel data from recent collections confirm the presence of at least two further Austrian cyphophthalmid species. (1) Siro cf. crassus Novak & Giribet, 2006 occurs in at least one location in SW Styria near the Slovenian border and hence represents a member of a second genus of Austrian sironids. (2) A further morphologically distinct sironid (“Sironidae gen. et sp. nov.?”) – so far undescribed and systematically not placed in detail – was collected in the borderland between Styria and Carinthia. All three species can be found in a small area of a few square-kilometers; although no syntopic occurrence was recorded.

Abundant and rare spiders on tree trunks in German forests (Arachnida, Araneae)

Abundant and rare spiders on tree trunks in German forests (Arachnida, Araneae)

Abstract

The spider fauna active on the bark of trees in forests on eight sites in different regions in Germany was investigated. Trunk eclectors at about 2-4 meters height on living trees were used in different regions of Germany (SW Bavaria, Hesse, Brandenburg) between 1990 and 2003. In Hesse eclectors were also used on dead beech trees (standing and lying). In this study data, mainly from beech (Fagus sylvatica) and spruce (Picea abies), from May to October are compared – whole year samples (including winter) are only available from Hesse. A total of 334 spider species were recorded with these bark traps, i.e. about one third of the spider species known from Germany. On average, each of the eight regions yielded 140.5 (± 26.2) species, each single tree 40.5 (± 12.2) species and 502 (± 452) adult spiders per season (i.e. May to Oct.). The 20 most abundant species are listed and characterised in detail. Six of the 20 species were not known to be abundant on bark, three prefer conifers and three beech/broadleaf. Even in winter (December-March) there was a remarkably high activity on the trunks. However, only a few species occur exclusively or mainly in winter. Finally, the rarity of some bark spider species is discussed and details (all known records in Germany, phenology) of four of them are presented (Clubiona leucaspis, Gongylidiellum edentatum, Kratochviliella bicapitata, Oreonetides quadridentatus). The diversity and importance of the spider fauna on bark in Central Europe is still underestimated.

On some new or rare spider species from Lesbos, Greece (Araneae: Agelenidae, Amaurobiidae, Corinnidae, Gnaphosidae, Liocranidae)

Abstract

In this paper, three new spider species are described from the Greek Aegean island Lesbos: Tegenaria maelfaiti sp. nov. (Agelenidae), Amaurobius lesbius sp. nov. (Amaurobiidae) and Agroeca parva sp. nov. (Liocranidae), as well as the unknown male of Arabelia pheidoleicomes Bosselaers, 2009 (Corinnidae). Diagnostic features and notes on ecology and distribution of these species are given. Two new records for the island are provided, such that currently 300 spider species are known from Lesbos.

The faunistic diversity of cave-dwelling spiders (Arachnida, Araneae) of Greece

The faunistic diversity of cave-dwelling spiders (Arachnida, Araneae) of Greece

Abstract

Until today, from Greek caves a total of 109 species of spiders belonging to 25 families are known. One species, the linyphiid Porrhomma convexum (Westring, 1861) was recorded here for the first time in Greece. The 109 species are distributed in caves of different geographic territories as follows: Thrace – 8 species, Macedonia – 18, Epirus – 1, Thessaly – 6, Central Greece – 3, Attiki-Saronic Islands – 24, Peloponnese – 15, Evoia-Vories Sporades – 1, Eastern Aegean Islands – 5, Cyclades – 3, Dodecanese – 6, Ionian Islands – 23, Crete – 47. The largest fraction of troglobite species were encountered mainly in the territories of Crete – 15 species (5 of which are anophthalmic), the Ionian Islands – 4, Thrace – 2 (both anophthalmic), the Attiki-Saronic Islands – 2 (both anophthalmic), the Peloponnese – 2 (one anophthalmic), and Macedonia, Thessaly, and the Cyclades – each with 2 species. The richness of the troglobitic spiders in these regions strengthens the assumption that they were major centres of speciation and evolution for the species of this group. According to their current distribution, the established 109 species can be classified into 12 zoogeograpical categories, grouped into 4 complexes (widely distributed, European, Mediterranean, endemics). The largest number of species belong to the endemic complex (53.2 %) and are also the most characteristic and reflect the local character of the cave-dwelling spiders.

A survey of spiders (Araneae) inhabiting the euedaphic soil stratum and the superficial underground compartment in Bulgaria

A survey of spiders (Araneae) inhabiting the euedaphic soil stratum and the superficial underground compartment in Bulgaria

Abstract

In 2005 a team of Bulgarian zoologists started a project aiming to study the invertebrates inhabiting the deeper soil stratum (euedaphon) and the Superficial Underground Compartment (SUC) in Bulgaria. In the course of a four-year sampling, a total of 52 species of spiders were caught from 19 collecting sites and 9 geographical regions. They belong to the following families: Scytodidae (1), Segestriidae (1), Dysderidae (8), Nesticidae (1), Anapidae (1), Theridiidae (1), Linyphiidae (20), Agelenidae (3), Cybaeidae (1), Dictynidae (2), Amaurobiidae (2), Liocranidae (3), Corinnidae (1), Zodariidae (1), Gnaphosidae (5), and Salticidae (1). The family Anapidae, with the species Zangherella relicta (Kratochvíl, 1935) is recorded from three sites in the Pirin and Slavyanka mountains, and this represents the first record of the family, genus and species in Bulgaria. In spite of the active investigations of the epigean and cave spiders in these regions over the years Z. relicta was not found and it seems it occurs only in deeper subterranean habitats and nowhere else. Comparative study of almost topotypic specimens of Z. relicta from Montenegro with those collected from Bulgaria showed no variation in the shape of palp and female vulvae. Until the true identity of Z. apuliae (Caporiacco, 1949) from Italy is revealed, it remains unclear whether Z. relicta and Z. apuliae are conspecific, as it remains unclear whether the older records of Z. apuliae from the Balkan Peninsula refer to this species or to Z. relicta. Pelecopsis mengei (Simon, 1884) (Linyphiidae) and Scotolathys simplex Simon, 1884 (Dictynidae) are also reported from Bulgaria for the first time, the latter being also new to FYR of Macedonia. A faunistic overview of the spiders found in these underground environments is made, along with remarks on the distribution and ecology of some rare and interesting species. The presence of cave-dwelling and superficial spiders in the sampled sites indicates that SUC and euedaphon are inhabited by different ecotypes, e.g. litter- (tanathostromic), soil- (edaphic) and cave-(troglobitic) which at some places co-occur.

The first fossil cyphophthalmid harvestman from Baltic amber

The first fossil cyphophthalmid harvestman from Baltic amber

Abstract

The first fossil cyphophthalmid harvestman (Opiliones: Cyphophthalmi) from Palaeogene (Eocene) Baltic amber is described. This is only the third fossil example of this basal harvestman lineage; the others being from the probably slightly younger Bitterfeld amber and the much older, early Cretaceous, Myanmar (Burmese) amber. Although incomplete and lacking most of the appendages, the new Baltic amber fossil can be identified as a female. The somatic characters preserved, especially spiracle morphology and the coxo-genital region, allow it to be assigned with some confidence to the extant genus Siro Latreille, 1796 (Sironidae). This fossil is formally described here as Siro balticus sp. nov. It resembles modern North American Siro species more than modern European ones, and can be distinguished principally on its relatively large size and the outline form of the body.

Spiders in a hostile world (Arachnoidea, Araneae)

Spiders in a hostile world (Arachnoidea, Araneae)

Abstract

Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders. Kleptoparasites are found among spiders as well as among Mecoptera, Diptera, Lepidoptera, and Heteroptera. Predators are found within spiders’ own population (cannibalism), among other spider species (araneophagy), and among different species of Heteroptera, Odonata, and Hymenoptera. Parasitoids are found in the orders Hymenoptera and Diptera. The largest insect order, Coleoptera, comprises a few species among the Carabidae which feed on spiders, but beetles are not represented among the kleptoparasites or parasitoids.

Endemic harvestmen and spiders of Austria (Arachnida: Opiliones, Araneae)

Endemic harvestmen and spiders of Austria (Arachnida: Opiliones, Araneae)

Abstract

A comprehensive overview of plant, fungus and animal species of Austria revealed a total of 748 endemic and subendemic species, including, 11 harvestman and 46 spider species. Altogether two endemic harvestmen (Nemastoma bidentatum relictum, Nemastoma schuelleri) and 8 endemic spiders (Abacoproeces molestus, Collinsia (caliginosa) nemenziana, Mughiphantes severus, Mughiphantes styriacus, Pelecopsis alpica, Scotophaeus nanus, Troglohyphantes novicordis, Troglohyphantes tauriscus), beside 9 subendemic harvestman and 38 subendemic spider species have been recorded from Austria. Hot-spots of endemism in the Eastern Alps are the north-eastern (Ennstaler Alps) and southern Calcareous Alps (Karawanken, Karnische Alps) and the Central Alps (Hohe Tauern, Gurktaler Alps, Ötztaler and Stubaier Alps). Most of the endemic arachnid species occur from the nival down to the montane zone. Important habitats are rocky areas, caves and woodlands. High absolute numbers and percentages of endemics can be found within the harvestman families Cladonychiidae, Ischyropsalididae and Nemastomatidae and in the spider genera Lepthyphantes s. l. and Troglohyphantes. The conservation status of these highly endangered taxa – 85 % of the spider species and 100 % of the harvestman taxa are endangered in Austria – is poor.

Ground-living spiders (Araneae) at polluted sites in the Subarctic

Ground-living spiders (Araneae) at polluted sites in the Subarctic

Abstract

Spiders were studied around the Pechenganikel smelter combine, Kola Peninsula, north-western Russia. The average spider density was 6-fold greater and the density of Linyphiidae specimens 11.5-fold higher at slightly polluted sites, compared with heavily polluted sites. Altogether, 18 species from 10 families were found at heavily polluted sites, the theridiid Robertus scoticus clearly dominating (23.3 % of identifiable specimens), also Neon reticulatus (9.6 %), Thanatus formicinus (9.6 %) and Xysticus audax (8.2 %) were abundant. The most numerous among 58 species found at slightly polluted sites were Tapinocyba pallens (18.5 %), Robertus scoticus (13.7 %), Maso sundevalli (9.5 %) and Alopecosa aculeata (8.2 %). The family Linyphiidae dominated at slightly polluted sites, 64 % of species and 60 % of individuals; compared with heavily polluted sites, 23 % and 38 % respectively.

Ground spider communities in experimentally disturbed Mediterranean woodland habitats

Ground spider communities in experimentally disturbed Mediterranean woodland habitats

Abstract

The protected Mediterranean woodland habitats in Israel are undergoing tree encroachment, resulting in loss of open patches with herbaceous vegetation. We suggested that this process results in a ground spider community dominated by shade-loving species. At three Mediterranean woodland sites located along a rainfall gradient, we examined the effects on the ground-spider community of experimental removal of the woody vegetation in 1000 m2 plots by cutting and overall plant biomass reduction by grazing and browsing by livestock. Pitfall traps were placed in replicated plots of four treatments (control, cutting, grazing/browsing, and cutting together with grazing/browsing) and in two different habitat patch types (open, woody). ANOVA and multivariate analyses were performed on family abundance by treatment and habitat patch type. Tree-cutting reduced the number of families in plots at two of the three sites. Grazing did not have a significant effect on the number of families or on the ground spider community composition. The spider community of cut-woody patches was more similar to that of open patches than to that of uncut woody patches. Most spider families separated along an axis of open versus woody patches, with woody habitat families predominating at all sites. Families typical of open habitats were positively associated with cut-woody patches as well. The overall effect on ground spider diversity of such manipulations may depend on the scale of habitat changes.

Spatial and temporal structure of the spider community in the clay semi-desert of western Kazakhstan

Spatial and temporal structure of the spider community in the clay semi-desert of western Kazakhstan

Abstract

The spatial and temporal structure of spider communities was studied in the clay semi-desert of the north-western Caspian Lowland, western Kazakhstan (49°23' N, 46°47' E). The soils and vegetation are complex, being composed of a mosaic of desert and steppe plant communities. Besides the native associations, there are plantations of different tree species. The ground-dwelling spider assemblages in the native habitats are the most diverse. The number of species inhabiting forest plantations is three times as small. Gnaphosidae is the leading family in the ground layer. They show high abundance and diversity levels during the whole season. Thomisidae, Lycosidae, Philodromidae, and Salticidae are abundant as well. The species diversity of herbage-dwelling spiders in different open native habitats is very similar. The spectrum of dominant families (Thomisidae, Oxyopidae, Araneidae, and Salticidae) and the seasonal dynamics of their ratio in desert and steppe associations have much in common. Spider assemblages of native and artificial habitats are characterised by change from multispecies polydominant spring-summer communities to impoverished imbalanced autumn ones. Seasonal changes in the species structure of mature spider groupings in native habitats are well pronounced, while the impact of seasonal conditions is even stronger than between-habitat differences. Complexes of typical species with different levels of habitat preference are revealed.

Regional variations in agrobiont composition and agrobiont life history of spiders (Araneae) within Hungary

Regional variations in agrobiont composition and agrobiont life history of spiders (Araneae) within Hungary

Abstract

Agrobiont spider species are well adapted to arable systems, which have fairly uniform vegetation structure and pest assemblages over continent-wide areas. We wanted to study, whether agrobiont spider subassemblages and the life history of the most prominent agrobiont, Pardosa agrestis, show any regional variation within Hungary, where only modest climatic differences exist between the NW and SE parts of the country. We studied agrobiont species of spider assemblages in 27 alfalfa and 21 cereal fields with suction sampling and pitfalls. The similarity structure of these agrobiont sub-assemblages (Sørensen distance measure) was congruent with the geographic distance matrices (Eucledian distance), as tested by Mantel tests. However, if we considered sub-assemblages consisting of the non-agrobiont species, this congruency was always higher. Thus, agrobionts responded only moderately to geographical variation if we compare them to non-agrobiont species. We studied the generation numbers and the occurrence of the first adult individuals in P. agrestis; the most common agrobiont spider in Hungary. This comparison involved comparing fields along a NW – SE gradient during 6 sampling years in pairwise comparisons, where in each year a northern and a southern population was compared with a minimum distance of 126 km in between. In generation numbers there was no difference; we found two generations across Hungary. In contrast, the first occurrence of adult individuals was on average 15 days earlier in both generations in the more southern populations. Thus, it can be concluded that agrobionts show a fairly stable and relatively low magnitude response over country-sized geographical ranges.

Cryptachaea blattea, eine weitere nach Deutschland eingeschleppte Spinnenart (Araneae: Theridiidae)

Cryptachaea blattea, a further spider species introduced into Germany (Araneae: Theridiidae)

Abstract

Cryptachaea blattea (Urquhart, 1886) has been recorded for the first time from Germany (Nordstemmen, rural district of Hildesheim, Lower Saxony). One male was found by means of pitfall traps in a tree and shrub nursery. The species was most likely introduced with plants or cargo. Information about its appearance, habitat, and distribution are given.

Spinnen (Arachnida, Araneae) im Winter - kleinräumige Unterschiede als Folge tageszeitlicher Temperaturschwankungen

Spiders (Arachnida, Araneae) in winter - differences in the appearance of species in small-scale spaces as a response to daily temperature fluctuations

Abstract

Pitfall traps were positioned for the investigation of the spider fauna at the northern and southern slopes of three mountain ridges (Chilchberg, Riedberg, and Buechenberg, municipalities Nunningen and Zullwil, canton Solothurn, Switzerland) within the Swiss Jura Mountains. The temperature in the upper litter was measured at three hour intervals. Independent of the weather more or less clear differences between northern and southern slopes could be observed. Maximum day temperature fluctuations of 15.8 °C were measured.

There were no significant differences in spider communities based on quantitative comparison methods. However, a qualitative analysis showed major differences in species composition. More than 50% of all species per investigation area showed clear preferences for the northern or the southern slope, with more then two thirds of the individuals only found on either the north or south slopes.

The previously unknown male of Steatoda ephippiata (Thorell, 1875) is described from recently collected material in Tunisia. Some new distribution records for the species are added and all known records are mapped.

The canopy spiders (Araneae) of the floodplain forest in Leipzig

The canopy spiders (Araneae) of the floodplain forest in Leipzig

Abstract

The canopy spiders of the floodplain forest in Leipzig have become a focus of ecological studies in recent years. In 2006 we sampled 30 tree canopies in the ‘Burgaue’ nature reserve with pyrethrum knock-down fogging, recording 502 adult spiders belonging to 48 species and 11 families. Based on these data and the results of a previous fogging study, the studied spider community was dominated by forest and forest-edge species with a preference for the shrub and canopy strata as well as by spiders of the web spider feeding guild. The community structure was typical for arboreal spider communities from northern temperate forests but very different from communities in the tropics. Species richness and evenness were similar to the old growth near-primary Białowieża Forest in Poland. The checklist of 96 canopy spider species of the floodplain forest of Leipzig includes 54 additions to the spider fauna of Leipzig and vicinity by recent canopy studies and eight first canopy records for Leipzig from our field work. The theridiid Dipoena torva (Thorell, 1875) was recorded for the first time in Saxony. The floodplain forest of Leipzig sustains a large and species-rich arboreal spider community and is thus a valuable habitat for a large proportion of endangered species (12%).

Abstract

The first record of the very rare linyphiid spider Ceraticelus bulbosus (Emerton, 1882) from Germany is presented. Furthermore records of Agroeca dentigera, Agyneta arietans, Bathyphantes setiger, Brommella falcigera, Crustulina sticta, Erigone dentigera, Meioneta mossica, and Pardosa morosa and other rare spiders are reported.

Diversity and distribution of spiders (Arachnida: Araneae) in dry ecosystems of North Rhine-Westphalia (Germany)

Diversity and distribution of spiders (Arachnida: Araneae) in dry ecosystems of North Rhine-Westphalia (Germany)

Abstract

The present study provides a robust data set for ecological planning and conservation of dry ecosystems in western Germany in general and North Rhine-Westphalia in particular. We summarised all available data from recent publications that dealt with spiders in dry ecosystems of North Rhine-Westphalia. Additionally, so far unpublished results of a detailed investigation regarding spiders in sand habitats of the Westphalian Bay that was conducted between 2006 and 2008 are presented. The analysis focussed on the habitat types according to Annex I of the EU Habitats Directive and related habitats. The investigation areas were scattered in the federal state of North Rhine-Westphalia. The data set comprised a total of 84436 individuals from 371 species and 28 families. Overall, an endangerment status is assigned to 68 species. Of these, 12 spiders are in imminent danger of becoming extinct. Two species, Erigonoplus globipes and Meioneta simplicitarsis, are believed to be extinct in North Rhine-Westphalia. Seven species (Dictyna major, Mastigusa arietina, Micaria formicaria, Styloctetor romanus, Thanatus striatus, Theridion uhligi and Xysticus ferrugineus) are new to the arachnofauna of North Rhine-Westphalia.

Nachweis fünf neuer Webspinnenarten (Araneae) für Schleswig-Holstein und Anmerkungen zu seltenen Arten in Niedersachsen

First records of five spider species (Araneae) in Schleswig-Holstein and remarks on species rarely found in Lower Saxony (Germany)

Abstract

Five species were recorded for the first time in Schleswig-Holstein, northern Germany: Psilochorus simoni (Berland, 1911) (Pholcidae), Ero aphana (Walckenaer, 1802) (Mimetidae), Panamomops mengei Simon, 1926 (Linyphiidae), Archaeodictyna consecuta (O. P.-Cambridge, 1872) (Dictynidae). Nigma walckenaeri (Roewer, 1951) (Dictynidae) is not considered to be rare, but a record is published from this region for the first time. A new northernmost distribution point for Theridion boesenbergi Strand, 1914 (Theridiidae) was recorded. Notes on other species rarely found in Schleswig-Holstein and Lower Saxony are also provided.

Zur Identifikation einer nach Deutschland eingeschleppten Kammspinnenart (Araneae: Ctenidae: Phoneutria boliviensis)

Identification of a wandering spider introduced into Germany (Araneae: Ctenidae: Phoneutria boliviensis)

Abstract

Data and a drawing of the epigyne of Phoneutria boliviensis (F.O. Pickard-Cambridge, 1897), recently recorded from Germany, are presented. The specimen was introduced with cargo (bananas) from Brazil. Characters of the single female are illustrated to facilitate identification in the future, since in the two recent revisions of the genus no drawing of the epigyne of P. boliviensis was included. Another case of introduction from 1998 of an unidentified subadult Phoneutria specimen, probably P. boliviensis too, with bananas from Ecuador is documented.

Neue Nachweise der Gerandeten Wasserspinne Dolomedes plantarius in Brandenburg (Araneae: Pisauridae)

New records of the great raft spider Dolomedes plantarius in Brandenburg (Araneae: Pisauridae)

Abstract

The great raft spider, Dolomedes plantarius (Clerck, 1757), is a rare and endangered species in Germany and other European countries. Current data on its distribution and ecology are briefly reviewed. Five new (or overlooked) localities for this spider from the Spreewald-region of Brandenburg in eastern Germany are provided, together with an updated distribution map. One record, based on the authors’ own collections, is described and figured in detail, with the egg-carrying female discovered in reeds at the edge of a fairly large body of open water. Both direct and indirect protective measures for the habitats of this species in the Spreewald-region are recommended.

On Roeweriella balcanica, a mysterious species of Marpissa from the Balkan Peninsula (Araneae, Salticidae)

On Roeweriella balcanica, a mysterious species of Marpissa from the Balkan Peninsula (Araneae, Salticidae)

Abstract

The taxonomic position of the poorly known species Roeweriella balcanica Kratochvíl, 1932 from Croatia is discussed. The species is illustrated and re-described on the basis of the female holotype. The genus Roeweriella Kratochvíl, 1932 (type species: R. balcanica Kratochvíl, 1932 by monotypy) is synonymized with Marpissa C.L. Koch, 1846, and therefore the new combination, Marpissa (Marpissa) balcanica (Kratochvíl, 1932) comb.nov., is proposed.

Hypsocephalus dahli is a junior synonym of Microneta pusilla (Araneae, Linyphiidae)

Hypsocephalus dahli is a junior synonym of Microneta pusilla (Araneae, Linyphiidae)

Abstract

Comparison of the detailed species-specific original drawings of Microneta pusilla Menge, 1869 with the holotype of Hypsocephalus dahli (Lessert, 1909) and the record of one female close to the type locality of Microneta pusilla in Gdańsk, Poland indicate that Hypsocephalus dahli is a junior synonym of Microneta pusilla. Hypsocephalus pusillus (Menge, 1869) is therefore proposed as the valid name for this species. Here we discuss the taxonomic status of both species and present a distribution map that accounts for records in Poland.

Hygropetric and litter-inhabiting spiders (Araneae) from the Abruzzo Apennines (Central Italy)

Hygropetric and litter-inhabiting spiders (Araneae) from the Abruzzo Apennines (Central Italy)

Abstract

We present the results of a study of spider material extracted by means of Berlese apparatus from wet mosses and by litter sieving in broadleaf woods within several natural reserves of the Abruzzo region (Central Italy). The main aim of the work is to contribute to the knowledge of the spider fauna of the Apennines; currently one of the lesser known in Italy. In total, 520 individual spiders, belonging to 49 species and 14 families were collected. The most abundant and diverse family was Linyphiidae, with 278 individuals belonging to 22 species. Altogether we provide 28 new records for the Abruzzo region, including two species of Theridiidae, 20 of Linyphiidae, four of Hahniidae and two of Thomisidae. We also present additional unpublished records of several rare, litter-inhabiting species collected by litter sieving in the same area. Data on habitat preferences and details on the Italian distribution of the rarest species are presented.

Taxonomic notes on Agroeca (Araneae, Liocranidae)

Taxonomic notes on Agroeca (Araneae, Liocranidae)

Abstract

Agroeca gaunitzi Tullgren, 1952 is stated here to be a junior synonym of A. proxima (O. P.-Cambridge, 1871). The illustrations of the male palp attributed to A. proxima in papers by Tullgren of 1946 and 1952 in fact show A. inopina O. P.-Cambridge, 1886. The record of A. inopina from Finland, quite outside its known distribution range, was based on a misidentification. It is argued that the type species of the genus Agroeca Westring, 1861 should be A. proxima (O. P.-Cambridge, 1871), not A. brunnea (Blackwall, 1833) as currently applied. Protagroeca Lohmander, 1944 is placed as an objective synonym of Agroeca Westring, 1861.

Erstnachweis der Wolfspinne Alopecosa barbipes (Araneae: Lycosidae) in Nordrhein-Westfalen

First record of Alopecosa barbipes (Araneae: Lycosidae) in North Rhine-Westphalia, Germany

Abstract

In September 2005, one male specimen of the wolf spider genus Alopecosa was discovered and photographed in heathland near Haltern, North Rhine-Westphalia, Germany. It was identified as A. barbipes (Sundevall, 1833), as it showed the species- and sex-specific tibial hair-brush absent in the sibling species A. accentuata. Three years later, two other specimens of A. barbipes were collected in the same area. These findings indicate that the species is more widespread than originally thought. Some details concerning the distribution of A. accentuata and A. barbipes and the problem of synonymy are discussed.

Spiders (Araneae) from the Panský diel (Starohorské vrchy Mts, Slovakia)

Spiders (Araneae) from the Panský diel (Starohorské vrchy Mts, Slovakia)

Abstract

Spiders were collected at the massif 'Panský diel' near the city of Banská Bystrica (Central Slovakia). We recorded 252 spider species for the territory and one new species for Slovakia. Although the summit reaches an altitude of 1.100 m a.s.l., more or less thermophilous species apparently prevail here, especially at lower moderate sites. On the other hand, only several typical oreophilous species were documented. Many recorded species are scarce or even very rare. This indicates the very high value of this territory from both a genetic and an environmental perspective.

Chthonius (Ephippiochthonius) poeninus – ein „Schweizer Endemit“ in den Allgäuer Alpen (Pseudoscorpiones: Chthoniidae)

Chthonius (Ephippiochthonius) poeninus – a “Swiss endemic species” in the Allgäu Alps (Pseudoscorpiones: Chthoniidae)

Abstract

In the course of a long term survey on the effects of grazing on the diversity of alpine grasslands, the false scorpion Chthonius (Ephippiochthonius) poeninus Mahnert, 1979 was recorded for the first time outside of Switzerland. The preferred habitat at the locality Alpe Einödsberg (Germany, Bavaria) differs strongly from previous findings. Our data suggest an association with Nardus grasslands (Geo montani-Nardetum), whereas earlier records originated from leaf litter, moss and mouldy trunks. Furthermore, the new records between 1540 m and 1973 m above sea level are the first from the subalpine region of the Alps (hitherto C. poeninus was known from 550 m to 1450 m). In the study region, extensive grazing seems to have a positive effect on the abundance of the species, while it is missing from intensively grazed pastures.

A glimpse of the tropics – spiders (Araneae) in the greenhouses of the Botanic Garden Berlin-Dahlem

A glimpse of the tropics – spiders (Araneae) in the greenhouses of the Botanic Garden Berlin-Dahlem

Abstract

In a survey of the spider fauna in greenhouses of the Botanic Garden Berlin-Dahlem, 30 spider species were recorded. Two species are new to Europe: Theotima minutissima (Petrunkevitch, 1929) and Heteroonops spinimanus (Simon, 1891). T. minutissima is the first member of the family Ochyroceratidae reported from Europe. Oecobius navus Blackwall, 1859 is new to Central Europe. Triaeris stenaspis Simon, 1891, is recorded from Germany for the first time. Zodarion italicum (Canestrini, 1868) is new to eastern Germany. Despite the discovery of some species previously unknown to Germany, the spider fauna in the Botanic Garden consisted mainly of wellknown synanthropic species and common inhabitants of greenhouses. Several alien spiders recently found in greenhouses, garden centers and houses were not recorded in the Botanic Garden. The species composition of the exotic spider fauna in greenhouses seems to depend chiefly on the specific modes of acquisition of plants and plant substrate.

Spinnen ökologischer Ausgleichsflächen in den Schweizer Kantonen Aargau und Schaffhausen (Arachnida: Araneae) – mit Anmerkungen zu Phrurolithus nigrinus (Corinnidae)

Spiders from ecological compensation areas in the Swiss cantons Aargau and Schaffhausen (Arachnida: Araneae) – with remarks on Phrurolithus nigrinus (Corinnidae)

View issue in browser

Abstract

The spider fauna of open habitats adjacent to arable land was investigated in northern Switzerland. The three habitat types were (1) herbaceous edges of fields (Sa), (2) fallow land sowed with flowers (BB), and (3) grass borders of fields (GS). Four funnel pitfall traps (10 cm diameter) were used to catch spiders in three stripe-types in two geographical regions in two years over 5 weeks in May and June: in total 12 sets of data. Spider species typical for open habitats were dominant, mostly lycosids (6 of the 10 most active species). The results were analysed together with environmental factors using a canonical correspondence analysis (CCA) and spiders were compared with carabid beetles (Coeloptera: Carabidae). Geographical region, though not very distant, had the largest influence on both spiders and carabids. The age and type of the habitats had a stronger influence on spiders than on carabids. In spiders a larger part of the total variance was explained by the analysed factors. Finally we discuss briefly a remarkable spider species. A review of all known records of Phrurolithus nigrinus in Switzerland and Germany, together with adjacent regions in France, is given. Its phenology is indicated, its habitat discussed and the overall distribution within Europe is listed.

Zur Ausbreitung humanmedizinisch bedeutsamer Dornfinger-Arten Cheiracanthium mildei und C. punctorium in Sachsen und Brandenburg (Araneae: Miturgidae)

Dispersal of two moderately venomous spiders Cheiracanthium mildei and C. punctorium in Saxony and Brandenburg (Araneae: Miturgidae)

View issue in browser

Abstract

In the summers of 2006 and 2007 presumed bites of Cheiracanthium spiders triggered mass hysteria in Austria and some regions of Germany, including northern Saxonia. Here we report the first records of Cheiracanthium mildei L. Koch, 1864 from Saxony and new records of C. punctorium (Villers, 1789) from Saxony and Brandenburg. C. punctorium is probably a native species in southern Germany. It shows a moderate area expansion that could be driven by global warming. Further records in north-western Saxony are to be expected. By contrast, C. mildei has to be regarded an invasive alien species that has rapidly spread into Central Europe from the Mediterranean. Leipzig is the north-easternmost locality in Europe reached so far, a further 230 km away from Nuremberg, the leading edge in 2006. A number of records in different districts of Leipzig suggest that the species is already established in the town. We also report verified bites of both species. The mild to moderate symptoms are in accordance with recent literature reviews.

Die Pseudoskorpion-Fauna (Arachnida: Pseudoscorpiones) eines Auwaldes bei Ingelheim am Rhein, unter besonderer Berücksichtigung der Auswirkungen des trocken-warmen Winters 2006/2007

The pseudoscorpion-fauna (Arachnida: Pseudoscorpiones) of a floodplain close to Ingelheim/Rhine, with special reference to the effects of the dry-warm winter 2006/2007

View issue in browser

Abstract

From the beginning of May 2005 to September 2007 the pseudoscorpion fauna in a hardwood floodplain forest of the Rhine valley near Ingelheim was investigated. Altogether 587 individuals representing two species from two families were captured using pitfall traps, trunk eclectors and by litter sieving. The warm, dry winter 2006/2007 exhibited a strong influence upon the activity of Neobisium carcinoides (Hermann, 1804). This winter event was followed by an extreme drought in April 2007, which affected the activity maximum of the corticolous species Chernes hahnii (C.L. Koch, 1839). In 2005 and 2006 the activity maximum of C. hahnii was observed in July, whereas in 2007 maturity was achieved earlier in May. Furthermore 31 individuals of N. carcinoides were captured in trunk eclectors. This climbing behaviour correlates with the presence of Lepidocyrtus lignorum (Collembola: Entomobryidae) on the trunks.

Leiobunum religiosum: neu für Deutschland (Arachnida: Opiliones)

Leiobunum religiosum (Arachnida: Opiliones): first record for Germany

View issue in browser

Abstract

L. religiosum Simon, 1879 was found at Mayen near Koblenz (Rhineland-Palatinate), Germany. This is the first record for Germany and is about 500 km from the known distribution area of the species in the southwestern Alps. The German population seems to be restricted to the ancient Roman quarry “Mayener Grubenfeld” where it is confined to stone walls and cave systems with balanced microclimatic conditions. Genital morphological structures were found to be very fragile, were easily deformed and therefore apparently variable. Difficulties in using these characters for taxonomy are discussed. Ecology, provenance and conservation status of the newly discovered population are considered.

From 2002 to 2003 a total of 11,194 mature spiders from 141 species and 20 families was caught by pitfall trapping and hand sampling. Among them are 18 species listed in the Red Data Book of North Rhine-Westphalia, four species are rare or previously rarely recorded. Most of the spiders are habitat generalists that extend their occurrence into all types of habitats, while the number of species which are stenotopic to sand habitats is noticeably low (n = 13). The spider data were analysed with Principal Component Analysis (PCA). It is possible to distinguish spider communities of neighbouring forested habitats from species groups of open habitats, but there is no uniform spider community which is characteristic for semi-dry grassland.

Spiders (Araneae) of the family Oonopidae in the Czech Republic

Spiders (Araneae) of the family Oonopidae in the Czech Republic

Abstract

The oonopid spiders (Oonopidae), Tapinesthis inermis (Simon, 1882) and Triaeris stenaspis Simon, 1891, are recorded for the Czech Republic for the first time. T. inermis was redetermined from misidentified material and T. stenaspis was discovered in a greenhouse.

Ein Beitrag zur Phänologie von Larinioides sclopetarius (Araneae: Araneidae)

A contribution towards the phenology of Larinioides sclopetarius (Clerck, 1757) (Araneae: Araneidae)

Abstract

We investigated a colony of Larinioides sclopetarius, the bridge spider, situated at a bridge-like dam in the city of Duisburg, Germany. The study ran from March until October 2004. The mean population density (all size classes) was 26.2 ind./m². The absolute maximum was found in July (71.3 ind./m²). Most of the spiderlings were found from June to October with mean densities up to 30.9 ind./m² in July, indicating that breeding of L. sclopetarius started in summer. Adult males and females occurred in spring, although the highest abundances (up to more than 3 individuals of each sex per m²) were found in summer and autumn. The adult sex ratio averaged over the study period was 1:1.2 (males:females). Some comparisons with other araneids, both solitary and social species, are drawn and discussed.

Spider (Arachnida: Araneae) distribution across the timberline in the Swiss Central Alps (Alp Flix, Grisons) and three morphologically remarkable species

Spider (Arachnida: Araneae) distribution across the timberline in the Swiss Central Alps (Alp Flix, Grisons) and three morphologically remarkable species

Abstract

We collected 6251 adult epigeic spiders from the dwarf-shrub heath to subalpine coniferous forest on Alp Flix (CH, canton Grisons, 1950 m) between May 2005 and May 2006 using pitfall traps. Total species richness and activity density of all species decreased from the open land to the forest, although this pattern varied according to family. The distribution of the 102 species found indicates that the small area around a single tree at the timberline provides habitats for both open land and forest spider species as well as some possible timberline specialists. Five species were new to the canton Grisons: Centromerita bicolor, Centromerita concinna, Hilaira excisa, Meioneta alpica and Tallusia experta. Three species showed remarkable morphological characteristics and were analysed in more detail. We found males of Pelecopsis radicicola without the characteristic longitudinal depression on the raised carapace. It is shown that the males of Meioneta alpica have a considerably variable lamella characteristica, which is nevertheless distinct from the sister species Meioneta ressli. Because we found intermediate forms of the head region described for Metopobactrus prominulus and M. schenkeli, respectively, M. schenkeli is considered a syn. nov. of M. prominulus. This study shows that the known distribution and taxonomic status of various spider taxa in the Central Alps are still incomplete and further work on arthropods in remote areas should be strongly encouraged.

An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)

An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)

Abstract

Since about the year 2000 a hitherto unidentified species of the genus Leiobunum C. L. Koch, 1839, has rapidly invaded central and western Europe. Records are known from The Netherlands (probably the country of first occurrence in Europe), Germany, Austria and Switzerland. This introduced species, until now, mainly inhabits walls of buildings and rocky environments. Adults characteristically aggregate during daytime into groups of up to 1.000 individuals. The species is described and details on its present distribution, habitat preference, phenology and behaviour are presented.

Erste Nachweise sowie Kenntnisse zur Biologie von Cyclosa oculata (Araneae: Araneidae) in der Schweiz

First records and data about the biology of Cyclosa oculata (Araneae: Araneidae) in Switzerland

Abstract

The orb-web spider Cyclosa oculata (Walckenaer, 1802) was found at eleven localities in north-western Switzerland. All records were from wildflower strips ("Buntbrachen") with a relatively high proportion of dried vegetation from the previous year, a relatively low vegetation height and a low proportion of grasses in the vegetation. C. oculata built its vertical orb-web near the ground, deep in the vegetation. Among ecribellate orb-web spiders in Central Europe, C. oculata is unique because it sometimes builds rudimentary webs on which it stays, because it builds its cocoons into the web, and because its stabilimentum is long-lasting and consists largely of debris. Based on our observations, we deduce that the stabilimentum of C. oculata serves as camouflage.

Zelotes tenuis (Araneae: Gnaphosidae) neu für Österreich

Zelotes tenuis (Araneae: Gnaphosidae) first record for Austria

Abstract

The first record of the Mediterranean spider Zelotes tenuis (L. Koch, 1866) in Austria (Burgenland, Leithaprodersdorf ) was made in a small meadow strip which is situated between a moist ditch and a small grassy road verge. The site is partly shaded by adjacent trees and shrubs. Notes are given on the records, zoogeography and ecology of Z. tenuis.

Emblyna brevidens (Araneae: Dictynidae) in the Mazurian Lake District (NE Poland) – rediscovered in Poland

Emblyna brevidens (Araneae: Dictynidae) in the Mazurian Lake District (NE Poland) – rediscovered in Poland

Abstract

Research was carried out on lake islands in the Mazurian region of NE Poland in 2004. During the study, 8546 specimens of 190 spider species were caught by Barber traps. One male of Emblyna brevidens (Kulczynski, 1897) was found on an island of Lake Wigry (Wigry National Park). This site was situated on the edge of a peat bog with Salicetum pentandro-cinereae, surrounded by wet alder forest. For the first time complete diagnostic drawings and measurements for both sexes of E. brevidens from Poland are given.

Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): neu für Deutschland und die Tschechische Republik

Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): first records for Germany and the Czech Republic

Abstract

N. bidentatum Roewer, 1914 was found at two places in Germany: first on the island “Harriersand” in the Weser river (Lower Saxony), second on the banks of the river Elbe in the Elbsandsteingebirge (Saxony). Adjacent to the latter locality an occurrence in the Czech Republic could be located close to the German/Czech border in the floodplain of the river Elbe as well. These records are the first for Germany and the Czech Republic. They enlarge the distribution area of N. bidentatum remarkably in both a northern and a western direction. The two populations show conspicuous differences in the form of the male cheliceral apophysis, which assigns them to the subspecies bidentatum Roewer, 1914 (in Lower Saxony) and sparsum Gruber & Martens, 1968 (in Saxony and the Czech Republik respectively). Differences, morphological characters and variability of the populations are illustrated. Relationships, abundance, ecology and provenance are discussed. N. dentigerum Canestrini, 1873 is recorded in Saxony for the first time. New records of N. triste C. L. Koch, 1835 and N. lugubre (Müller, 1776) are given.

Arachnologie im Senckenberg: von Wider bis Wiehle

Arachnology at Senckenberg: from Wider to Wiehle

Abstract

The development and present status of arachnology at the Senckenberg-Museum (Frankfurt) are critically reviewed. Extended periods of care and maintenance were followed, from 1955 onwards, by flourishing decades, including considerable enlargement of the collections. One of the most complete libraries in the field originated from this time. Progress culminated in the arrangement of meetings and finally of international congresses, including the foundation of what is now the International Society of Arachnology (formerly C.I.D.A.). Data on some relevant authors such as Roewer and Wiehle are included.

Zoropsis spinimana (Araneae: Zoropsidae) neu für Deutschland

Zoropsis spinimana (Araneae: Zoropsidae) first record in Germany

Abstract

The first two records of Zoropsis spinimana (Dufour, 1820) in Germany are presented together with a further discovery of the species in Central Switzerland. A spreading of the species from South to North along traffic routes is supposed and climate change is suggested as a possible reason for the species establishing itself in Central Europe.

A new feature for the separation of Trochosa spinipalpis and T. terricola males (Araneae, Lycosidae)

A new feature for the separation of Trochosa spinipalpis and T. terricola males (Araneae, Lycosidae)

Abstract

A new feature on the tip of the palp, which enables the separation of male Trochosa spinipalpis (F. O. P.-Cambridge, 1895) from T. terricola Thorell, 1856, is described. T. terricola exhibits a hairless strip on the tip of the palp, while T. spinipalpis lacks this feature and has long hairs on the whole palp.

Abstract

The genus Araeoncoides Wunderlich, 1969, containing a single species A. berolinensis Wunderlich, 1969, is revised and transferred to the genus Moebelia Dahl, 1886 (nov. syn.). The female is described for the first time. All six known records are reported. Distribution, habitat and phenology are discussed. Until now, records are known exclusively from Germany.

Weberknechte (Arachnida: Opiliones) in Mischbeständen aus Fichte und Buche im Vergleich zu Fichten- und Buchenreinbeständen – eine Studie im Solling

Harvestmen (Arachnida: Opiliones) in mixed and pure stands of spruce and beech – a study in the Solling mountains

Abstract

In the Solling mountains (Southern Lower Saxony, Germany) a block design study was carried out in 18 old (> 90 yrs) and middle-aged (58 - 89 yrs) spruce, beech, and mixed forest stands (spruce/beech), arranged in six blocks, each consisting of a spruce, a beech, and a mixed forest stand, to investigate the effect of the forest stand type on the diversity and structure of epigeic macrofauna communities. In each age class, the fauna was sampled for one year by means of soil core samples, ground photo eclectors, and pitfall traps. The results for the harvestmen presented in this contribution focus on pitfall trap catches. In each age class, the numbers of individuals of the harvestmen species and the species density as well as the cover and diversity of the ground vegetation were significantly highest in the more open spruce or spruce and mixed forest stands, according to a nonparametrical twofactorial analysis of variance. Important extrinsic factors influencing the diversity and structure of the harvestmen communities are habitat diversity, stratification of the vegetation, and space for locomotory activity. Additionally, in the present study information about the phenology of the harvestmen species is given. In the Solling mountains 16 harvestmen species have been recorded to date.

On Pardosa schenkeli (Araneae, Lycosidae) and its presence in Germany and Poland

On Pardosa schenkeli (Araneae, Lycosidae) and its presence in Germany and Poland

Abstract

The wolf spider Pardosa schenkeli Lessert, 1904 was since long regarded as occurring in Germany and Poland but is excluded from the recent checklist of spiders found in these countries. Re-examination of material collected in Germany and Poland, respectively, verifies its presence in both countries. Characters for distinguishing P. schenkeli and its ally P. bifasciata (C.L. Koch, 1834) are given and illustrated.

Stammbewohnende Weberknechte (Arachnida: Opiliones) in einem Fichten- einem Misch- und einem Buchenbestand im Solling

Stem-inhabiting harvestmen (Arachnida: Opiliones) in a spruce, a mixed, and a beech stand in the Solling mountains

Abstract

In the Solling mountains (Southern Lower Saxony, Germany) the fauna was sampled for one year with stem eclectors in adjacent spruce, mixed (spruce/beech), and beech stands. The tree age was more than 90 years. Four sampling treatments were established: eclectors on spruce stems in the spruce stand (1), on beech stems in the beech stand (2), and on spruce (3) and beech stems in the mixed stand (4). The following harvestmen species, with 1601 individuals in total, were found: Mitopus morio, Oligolophus tridens, Platybunus bucephalus, Leiobunum blackwalli, and Leiobunum rotundum. The number of individuals was highest on spruce stems in the more open spruce stand, mainly due to Mitopus morio, whereas number of species was highest on beech stems in the mixed stand. Both the number of individuals and species were lowest on beech stems in the beech stand. Here, additional information about the phenology of the harvestmen species is given.

Morphological separation of the Central European Trochosa females (Araneae, Lycosidae)

Morphologische Unterscheidung der der mitteleuropäischen Trochosa-Weibchen (Araneae, Lycosidae)

Abstract

Adult females of the five Central European wolf spiders Trochosa hispanica Simon, 1870, T. robusta (Simon, 1876), T. ruricola (DeGeer, 1778), T. spinipalpis (F.O.P.-Cambridge, 1895), and T. terricola Thorell, 1856 were morphologically analysed. We defined sets of continuous and binary (presence/absence) variables. Continuous data of various epigynal and carapace dimensions were subjected to Principal Component Analysis (PCA). Using the PC loadings each individual was plotted along the PC axis in order to find gaps(overlaps between the species. The binary data sets were subjected to Hierarchical Cluster Analysis (HCA) in order to find characters that clearly separate the five Trochosa species. Using PCA only individuals of T.robusta and T.ruricola and of T.robusta and T.hispanica could be separated from each other. Using HCA all five species could clearly be separated by epigynal and vulval characteristics."

Zum Vorkommen von Atypus affinis und Atypus piceus (Araneae: Atypidae) auf einer Sukzessionsfläche im flurbereinigten Rebgelände des Kaiserstuhls

The distribution of syntopic Atypus affinis and Atypus piceus (Araneae: Atypidae) in a succession area of vine-yard slopes in the Kaiserstuhl (south-western Germany)

Abstract

The orthognath spiders Atypus affinis Eichwald, 1830 and A. piceus (Sulzer, 1776) are morphologically and biologically similar. One of the few sites where both species live syntopically is located in the Kaiserstuhl Mountains in south-west Germany. This has been shown in a continuous 22 year long-term study of the recolonisation of vineyard slopes after large-scale land consolidation. The males of both species differ in size and the annual timing of their surface activity. The recolonisation history of A. affinis and A. piceus was recorded. As typical K-strategists, their population sizes have increased slowly. Today they are still growing. Atypus species can be used as models regarding problems of nature conservation, since they are particularly endangered by large-scale and catastrophic habitat changes as a result of their long generation time. In the Kaiserstuhl such catastrophic events could include fire management, which has recently been permitted again for the preservation of the slopes.

Drassodes lapidosus und Drassodes cupreus (Araneae: Gnaphosidae) – eine unendliche Geschichte

Drassodes lapidosus and Drassodes cupreus (Araneae: Gnaphosidae) – a never-ending discussion

Abstract

According to Platnick (2006) the taxa Drassodes lapidosus (Walckenaer, 1802), the type species of the genus Drassodes (Westring, 1851), and Drassodes cupreus (Blackwall, 1834) are two valid species. However Grimm (1985) merged them into one taxon. Different taxonomists have separated these species by the positions of the teeth in the frontal margin of the chelicerae and by the proportions of the palpal segments in males. Females are separated by the proportions of different features in the epigyne. The altitude at which they occur is used for separation, too. The aim of this paper is to discuss whether these characteristics really allow the separation of these two taxa. In order to solve these taxonomical problem, 116 male and 108 female specimens from Central Europe were examined. The variation of the mentioned characters is shown. Spearman's rho correlations and factor analyses are presented. The results show that there are transitions between the two taxa D. lapidosus and D. cupreus and, thus, they cannot be separated using the diagnostic features currently available.

Spinnen aus Baumkronen-Klopfproben (Arachnida: Araneae), mit Anmerkungen zu Cinetata gradata (Linyphiidae) und Theridion boesenbergi (Theridiidae)

Spiders from branch-beating samples in tree crowns (Arachnida: Araneae), with remarks on Cinetata gradata (Linyphiidae) and Theridion boesenbergi (Theridiidae)

Abstract

In winter 2000/01 and in June 2001 branch-beating methods were used for sampling spiders in canopies of spruce (Picea abies) and Douglas-fir (Pseudotsuga menziesii) in SW-Bavaria (Germany). Differences in spider assemblages between the two species are discussed with particular emphasis on the dominant species and taxa. For the rare species Theridion boesenbergi Strand, 1904 remarks on their occurence in Bavaria, Germany and Europe are given. For Cinetata gradata (Simon, 1881) we present an update to the entire known distribution including a new map. For both species new records are specified and discussed concerning habitat preference, phenology and distribution. Both species seem to be obligate tree colonisers, C. gradata primarily in the canopy stratum. Adults of C. gradata are to be found during all months of the year; T. boesenbergi exhibits an abundance peak in June, males are known to occur from May to August and females the whole year round. The distribution of both species is restricted to Europe, excluding the northern and western parts (Arctic and Atlantic climate) and the Mediterranean zone.

Abundanz und Vikarianz epigäischer Weberknechtarten (Arachnida: Opiliones) in einem Auwaldgebiet des Mainzer Beckens

Abundance and vicariance of epigeic opilionids (Arachnida: Opiliones) of an inundation forest in the "Mainzer Becken", Germany

Abstract

From the beginning of November 2003 to January 2004 the opilionid fauna was collected in a floodplain forest of the Rhine valley west of Mainz. Altogether 1643 individuals were captured in pitfall traps; these belong to six species representing three families. The thermophilous species Astrobunus laevipes, Nemastoma dentigerum and Trogulus martensi are noteworthy for this habitat. Results on the phenology of three stenochronous species over the sample periods are presented, and both activity abundance and dominance were measured. Additionally survival strategies for flooding periods are proposed and vicariance and concurrence with related species are discussed.

Neue Nachweise bi- und unisexueller "Populationen" von Megabunus lesserti (Opiliones: Phalangiidae) in den Nordostalpen

Bisexuals surrounded by all-female clones: new records of Megabunus lesserti (Opiliones: Phalangiidae) in the north-eastern Alps

Abstract

New data on the sex ratio of 16 populations of the endemic harvestman Megabunus lesserti Schenkel, 1927 in the northeastern Alps confirm the previously assumed pattern of geographic parthenogenesis. Bisexuals inhabit a small area between the eastern margin of the Northern Calcareous Alps and the Ennstaler Alps, which was covered by ice during the last (Würm) glaciations. Postglacially recolonized areas are occupied by parthenogenetic clones. Some all-female samples were found in close geographic proximity to bisexual populations. Apparently isolated occurrences at the western (Ammergau Alps) and southwestern (Carinthian) limits of the range proved to consist exclusively of females. A single male recorded in the Karwendel Mts. near Innsbruck is interpreted preferentially as a case of spanandry, being a fatherless "mistake" without any significant function.

Mittel- und nordeuropäische Weberknechte aus dem Senckenberg Museum Frankfurt (Arachnida: Opiliones)

Central and North European harvestmen from the Senckenberg Museum Frankfurt (Arachnida: Opiliones)

Abstract

About 1100 individuals belonging to 32 opilionid species (300 series), mainly of German origin, were identified based on material provided by, and stored at, the Senckenberg Museum, Frankfurt (Main). A list of all species with habitat information is included. Comments on two remarkable species (Oligolophus hanseni, Odiellus spinosus) are given. The comments include the importance of some series as reference material from MARTENS (1978), additions to regional faunas and the expansion of the known distribution of some thermophilous species.

Die Zönose der Araneae in Kiefern- und Birkenforsten rekultivierter Tagebaukippen in Sachsen und Brandenburg

The spiders (Araneae) of pure pine and birch stands on restored open dump sites in Saxony and Brandenburg (Germany)

Abstract

The spider communities of four restored, afforested pure stands of first generation pine, birch and birch-robinia in the postmining landscape and one natural pine forest of the Lower Lusatia (Germany: Saxony and Brandenburg) were investigated. From 1997-98 a total of 6,368 spiders were caught using stemeclectors and pitfall traps. More than 50% of the specimens collected were juveniles. The remaining individuals were identified and represent 123 from 23 families. Among them are several taxa listed in the Red Data Lists of Germany (n = 16), Brandenburg (n = 13) and Saxony (n = 14). One species, Clubiona leucaspis is rare for Germany and new to Saxony. When comparing afforested stands of pine on postmining areas with natural ones the species Coelotes terrestris (Amaurobiidae) was observed exclusively in the latter. The absence of this species on restored sites seems to indicate a disturbance of the soil up to almost 60 years after the end of restoration. According to pitfall trapping in three pine forests the increasing biomass of spiders indicates a high predation rate at the oldest site, whereas the highest species diversity was found on younger, rehabilitated sites.

Zimiris doriai (Araneae: Prodidomidae) – erstmals nach Deutschland eingeschleppt

Zimiris doriai (Araneae: Prodidomidae) – introduced to Germany

Abstract

Two specimens of Zimiris doriai Simon, 1882 have been found in a container shipped from Vietnam. The family Prodidomidae has not been recorded yet from Germany, and is characterised by 1. the anterior position and the elongated shape of the anterior-lateral spinnerets and 2. by their strongly procurved posterior eye row. Characters for identifying the species are presented.

Cicurina japonica (Araneae: Dictynidae) – eine nach Mitteleuropa eingeschleppte Kräuselspinnenart

Cicurina japonica (Araneae) – a dictynid spider introduced into Central Europe

Abstract

This paper presents the first two European records for the dictynid species Cicurina japonica (Simon, 1881), originally distributed in East Asia. The many specimens caught in the former freight railway station of the "Deutsche Bundesbahnen" (DB) in Basel allow us to present some ideas about the ecology of the species.

Regional variation of habitat tolerance by some European spiders (Araneae) – a review

Regional variation of habitat tolerance by some European spiders (Araneae) – a review

Abstract

The data presented by Hänggi et al. (1995) and Bolaños (2003) on the habitats of a large number of European spiders are examined, most of which appear to show non-specific preferences. The abundance and frequency peaks of the 384 species graphs (HÄNGGI et al. 1995) can be explained by assuming that habitat tolerance varies with geographical location. This can be demonstrated on a local level within a particular country or throughout the European range of a species. Examples are described. Many published ecological studies of spider faunas seem to have assumed that the habitat preferences of a species is a fixed characteristic wherever they occur but evidence is presented to show that this may apply to only a few species. A number of examples are described showing how preferences change with latitude and longitude within Europe. It is proposed that most species can be categorised as stenotopic, mesotopic or eurytopic, although there is a gradual change from one group to another, with no clear boundaries. Supporting evidence for regional variation in habitat tolerance is scarce. More studies are required of individual species throughout their European distribution and detailed descriptions of their habitats in different parts of their range. Definitions of micro-, macro- and minor habitats are presented as useful tools for field studies of spider faunas. It is also recommended that future faunal surveys should use the same system of habitat classification so that the results are comparable with other studies. The most appropriate method is described by BUCHAR & RUŽICKA (2002) but could be made more precise by the use of scientific measuring equipment for light/shade, dryness/humidity and temperature. Finally the importance of checking the validity of some published records is stressed because misidentifications are sometimes frequent.

Ergänzungen und Berichtigungen zum "Verzeichnis der Spinnen (Araneae) des nordwestdeutschen Tieflandes und Schleswig-Holsteins" von Fründ et al. (1994)

Additions and corrections to the 'Catalogue of spiders (Araneae) of the north-west German Lowland and Schleswig-Holstein' by Fründ et al. (1994)

Abstract

85 literature sources and 61 spider species have to be added to the "Catalogue of spiders of the north west German Lowland and Schleswig-Holstein", published in 1994. Nine species have to be omitted from the original list. Currently, the total number of spider species in the region is 653, including at least 21 doubtful records. This overall large regional species pool obviously results from the large size of the area included and its landscape diversity with coastal zones as well as lowlands with both anthropogenic and natural habitats of different natural landscapes.

Ein seltener Parasitoid der Wolfspinne Pardosa alacris (Araneae: Lycosidae): Ogcodes gibbosus (Diptera: Acroceridae)

A rare parasitoid of the wolf spider Pardosa alacris (Araneae: Lycosidae): Ogcodes gibbosus (Diptera: Acroceridae)

Abstract

The emerging of an acrocerid fly from an adult female of the wolf spider Pardosa alacris (C.L. Koch, 1833) was observed near Karlsruhe (Baden-Württemberg, Germany). This record supports previous results suggesting that acrocerids infect the spider's body, and not the egg sac. A short review of the life history of acrocerids and the development of their larvae is provided, casting doubt on the infection of spider cocoons by these parasitoids

Neue Funde von Atypus muralis (Araneae: Atypidae) in Sachsen-Anhalt

New records of Atypus muralis (Araneae: Atypidae) in Saxony-Anhalt (Germany)

Abstract

The paper presents new records of the spider Atypus muralis Bertkau, 1890 in the valleys of the rivers Saale and Unstrut in the south of Saxony-Anhalt in Middle Germany. All specimens were males, caught by pitfall traps in xerothermic steppic grasslands on steep slopes. The geographic distribution of Atypus muralis in the eastern parts of Germany and habitat traits are discussed with special reference to regional climate, vegetation type and soil conditions. The phenology of aboveground activity of Atypus muralis males is shown.

Zur Kenntnis der Pseudoskorpion-Fauna von Ostdeutschland (Arachnida, Pseudoscorpiones)

On the knowledge of the pseudoscorpion fauna of East Germany (Arachnida, Pseudoscorpiones)

Abstract

Based on the examination of over 23,000 specimens, distribution, frequency/dominance, morphometric data and ecology of the East German false scorpions are presented. Most samples were collected by the authors, the rest are from Museums and other persons. 38 species were recorded. The preferred habitats and strata of the most species are described. Phoresy was observed for Allochernes peregrinus, Lamprochernes chyzeri, L. nodosus and Pselaphochernes scorpioides. Nine species live in ant nests. Zoogeographic aspects of the species assemblage are discussed in the world wide context. Distribution limits of four species run across the area of investigation.

Larinioides sclopetarius, eine parasoziale Spinne Mitteleuropas?

Larinioides sclopetarius, a parasocial spider of Central Europe?

Abstract

Larinioides sclopetarius is one of very few Central European spiders known to be found in colonies in which the orb-webs are attached to each other. Indiviuals of different generations cooperate at least in web-building, i.e. they share the same framework or irregular "web carpet". This behaviour is called parasocial and up to now it has been studied mainly in subtropical and tropical species. Parasocial (colonial) life can lead to total degeneration of the orb-webs and is the result of increased tolerance, which depends on local superabundance of prey. Initial surveys in Essen (Germany) showed that groups of 60 to 200 individuals do not seem to be exceptional. More detailed studies on the group-living of L. sclopetarius are needed.

Bodenbesiedelnde Spinnen (Arachnida, Araneae) eines Kiefernforstes bei Stücken in Brandenburg, Deutschland

Ground living spiders (Arachnida, Araneae) of a pine forest near Stücken in Brandenburg, Germany

Abstract

Ground inhabiting spiders were investigated during the vegetation periods of , 1998 and 2000 in four pine forests of Brandenburg, Germany. 1995 three of them were managed in different ways and one area served as a control. In total 105 different species were found and the lowest number of species was found on the control area. Due to the management the pine forests got opened and xerophilous species could settle the areas. In total a heterogeneous species community was found on each area. From year to year high rates of species turnover were measured even for the dominant species (> 5 % of all collected individuals per area and year). Some endangered species in Brandenburg were collected as well.

Untersuchungen zur Spinnenfauna (Araneae) an Mittelgebirgsbächen und zur Besiedlung neu entstandener Uferstrukturen

The spider community (Araneae) of low mountains streams and investigations on the colonization of newly-developed gravel bars

Abstract

In 2000 and 2001 the spider communities along ten low mountainous streams in Thuringia, Hesse and Lower Saxony were studied. Pitfall traps were set along a perpendicular transect extending from close to the water's edge to a distance of about 10-30 m away. Additonally, hand collectionwithin defined areas and time-frames was carried out. In order to investigate colonization patterns experimentally, coarse substrate was exposed simultating newly-developed bars. In total 164 species were detected. 138 species were caught only in the pitfall traps of which 75 (54%) species were caught not only in grassland but also in other floodplain habitats. 19 speciese were restricted to unvegetated banks or open stream bars. 12 species had a significantly higher abundance along restored sections compared to sections which are still regulated, and therefore would be positively influenced by increased fluvial dynamics whereas no species showed a significantly reduced abundance in response to restoration. Oedothorax agrestis, Pirata knorri and Pirata latitans are regarded as typical for the riparian spider community of low mountainous streams.
