Arachnologische Mitteilungen 55

Arachnologische Mitteilungen / Arachnology Letters 55: 1-9 Karlsruhe, April 2018 In the early twentieth century Chyzer & Kulczyński (1918) published the first comprehensive checklist of the spiders from Hungary, and already listed 742 species. More than 80 years later Samu & Szinetár (1999) updated the list accor- ding to the present borders of Hungary, thus their list con- tains 725 species. Since then many new additions have been reported for the fauna (e.g. Szűts et al. 2003, Pfliegler et al. 2012, Szinetár & Kovács 2013, Pfliegler 2014, Szinetár et al. 2014, 2015, Korányi et al. 2017) and several new species from the country were described (Szinetár & Samu 2003, Szinetár & Kancsal 2007, Szinetár et al. 2009, Kovács et al. 2015a). Presently, the Spiders of Europe database lists 800 spider taxa for Hungary (Nentwig et al. 2017), although the list is still far from complete. In this paper we report two further spider spe- cies which are new to the fauna of Hungary. We also provide a new data on the occurence and biology of some rare and interesting spider species. Material and methods The spiders were collected sporadically in various parts of Hungary, mainly in apple orchards (Bács-Kiskun, Pest, Sza­ bolcs-Szatmár-Bereg and Tolna counties) and city parks (Budapest, Gödöllő) from 2013 to 2016. Exact locations are indicated with some comments in the Results. A variety of collecting methods were used, including hand collecting, beating, cardboard bands and litter sampling. For collect- ing overwintering spiders from apple trees, we used corru- gated cardboard stripes (height 20 cm), which were placed around the tree trunks, at about 20 cm above ground usually in September. The bands and litter samples were collected during winter months, and for processing the litter samples we used Winkler extractors (Sakchoowong et al. 2007). Juve- nile specimens of Philodromus marmoratus Kulczyński, 1891 and Pulchellodromus ruficapillus (Simon, 1885) were kept alive and fed with Drosophila hydei Sturtevant, 1921, until its fi- nal moult.The collected and reared specimens were stored in 70 % ethanol. Individuals were examined in the laboratory of the Department of Entomology, Szent István University. Identification was made under a binocular stereo microscope (Leica MZ6). In case of female specimens the genitalia were dissected from the specimens, and the epigynes/vulvas were cleared with 20 % KOH.The specimens were identified using various keys (see in the Results section), and were deposited in the first author’s private collection. Philodromus marmoratus and P. ruficapillus habitus pictures were taken with a Nikon D3300 camera equipped with a Sigma 50mm 1:2.8 DG Macro lens. Iberina microphthalma (Snazell & Duffey, 1980), Porrhomma oblitum (O. P.-Cambridge, 1871) and P. ruficapil­ lus epigynes/vulvas were photographed with a Zeiss Imager A2 light microscope equipped with AxioCam MRc5, and in other cases the photographs were taken with a Sony XCD- SX90CR digital interface connected to a Zeiss Stemi 2000 stereomicroscope. The specimens’ parameters were measured with an ocular micrometer calibrated with a stage micrometer, and for post-processing work on the photographs, and for the preparation of the scale bars we used Adobe Photoshop CS3 software. Taxonomic names follow the nomenclature of the WSC (2017). Results and discussion As a result of our study the following ten new or rare spider species were recorded from Hungary: Araneidae Clerck, 1757 Cyclosa sierrae Simon, 1870 (Fig. 1) Determination.

This study reports the first records of two spider species for Hungary: Cyclosa sierrae Simon, 1870 (Araneidae) and Porrhomma oblitum (O. P.-Cambridge, 1871) (Linyphiidae). Cyclosa sierrae also represents the first record of this species from Central Europe. Further- more, we provide evidence about the occurence of Dysdera lata Reuss, 1834 and Philodromus marmoratus Kulczyński, 1891 in Hungary and for six further species we report new data: Brigittea vicina (Simon, 1873) (Dictynidae), Iberina microphthalma (Snazell & Duffey, 1980) (Hahniidae), Mermessus trilobatus (Emerton, 1882) (Linyphiidae), Pulchellodromus ruficapillus (Simon, 1885) (Philodromidae), Lasaeola prona (Menge, 1868) (Theridiidae) and Diaea livens Simon, 1876 (Thomisidae). Comments on the distribution, biology and taxonomy of the ten mentioned spider species are provided. Keywords: Cyclosa sierrae , distribution, Dysdera lata , first record, Philodromus marmoratus , Porrhomma oblitum Zusammenfassung. Einige seltene und bemerkenswerte Spinnenarten aus Ungarn (Arachnida: Araneae). Diese Untersuchung enthält die Neunachweise von zwei Spinnenarten für Ungarn: Cyclosa sierrae Simon, 1870 (Araneidae) und Porrhomma oblitum (O. P.- Cambridge, 1871) (Linyphiidae). Cyclosa sierrae wird damit auch erstmals für Mitteleuropa gemeldet. Weiterhin werden Dysdera lata Reuss, 1834 und Philodromus marmoratus Kulczyński, 1891 für Ungarn belegt und von sechs Arten werden neue Daten präsentiert: Brigittea vicina (Simon, 1873) (Dictynidae), Iberina microphthalma (Snazell & Duffey, 1980) (Hahniidae), Mermessus trilobatus (Emerton, 1882) (Linyphiidae), Pulchellodromus ruficapillus (Simon, 1885) (Philodromidae), Lasaeola prona (Menge, 1868) (Theridiidae) und Diaea livens Simon, 1876 (Thomisidae). Verbreitung, Biologie und Taxonomie der zehn Arten werden diskutiert.
