250 years „Svenska spindlar / Aranei Svecici“

Abstract

On the occasion of the anniversary of C.A. Clerck's book "Swedish spiders" the paper deals with the beginnings of spider taxonomy, Clerck's life (1709-1765) and work, and P. Bonnet's successful campaign for the validation of species names given by Clerck.

Erstfund von Hahnia picta (Araneae, Hahniidae) in Deutschland – mit Angaben zu Habitatpräferenz und Verbreitung

First record of Hahnia picta (Araneae, Hahniidae) in Germany – with data on habitat preference and distribution

Abstract

A female of the dwarf sheet spider Hahnia picta Kulczynski, 1897 was found in an old castle park in Berlin (Germany). All published records as well as unpublished records from Austria are listed and mapped. This species is rarely recorded. Its distribution is confined to Europe. H. picta seems to live exclusively under the bark of old deciduous trees.

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.

Chthonius (Chthonius) heterodactylus (Pseudoscorpiones: Chthoniidae), eine neue Art für die Tschechische Republik

Chthonius (Chthonius) heterodactylus a new species of pseudoscorpion (Pseudoscorpiones: Chthoniidae) for the Czech Republic

Abstract

Chthonius heterodactylus Tömösváry, 1882 is recorded for the first time from the Czech Republic (Hranická chasm). The occurence of this Carpathian species in Central Europe is discussed and the positions of the type localities are corrected.
