Arachnologische Mitteilungen 57

Arachnologische Mitteilungen / Arachnology Letters 57: 8-20 Karlsruhe, April 2019 The genus Zodarion Walckenaer, 1833 has a Palaearctic dis- tribution and currently consists of 163 species (World Spider Catalog 2018). Especially the Mediterranean region appears to be rich in species of this genus. In the western part (Iberi- an Peninsula), 32 species have been reported (Bosmans 1994, Pekár et al. 2003, Pekár & Cardoso 2005). In the Central Me- diterranean region (France, Italy) 19 species have been repor- ted (Bosmans 1997) and in the Balkans 42 species (Bosmans 2009). In the present contribution, four new species are de- scribed including new distribution data for 43 other species. Material and methods Most of the material was collected by the first author du- ring different collecting trips to the Mediterranean region. The material from Sardinia is the result of a project on faunal studies in Sardinia and was collected by M. Verdinelli and A. Sassu.The material from Greece originates from fieldwork included in a faunistic project (SPIDOnetGR, ARISTEIA II Programme, NSRF 2007–2013) lead by M. Chatzaki. A few colleagues sent material for identification, and these data are included as well. Specimens were examined and illustrated using a Nikon SMZ1270 stereomicroscope. Further details were studied using an Olympus CH-2 stereoscopic microscope with a dra- wing tube. Photographs were taken with a Moticam 5MP ca- mera attached to a Realux stereoscopic microscope. Somatic morphology measurements were taken using a scale reticule in the eyepiece of the stereo microscope and are in mm. Mea- surements of the legs are taken from the dorsal side. Taxono- mic descriptions follow the format of Bosmans (1994, 1997, 2009). Left structures of palps are depicted. Eye measurements were based on the lens at its widest point. Female genita- lia were excised using sharpened needles. These where then transferred to clove oil for examination under the microscope. Male palps were detached and transferred to glycerol for ex- amination under the microscope. Later, palps and epigynes were returned to 70 % ethanol. Type material and important reference material is depo- sited in different museums as listed in the descriptions of the species, the other material is deposited in the collection of the collectors or in one of the collections listed below.

The following new Zodarion species are described from Italy: Zodarion pantaleonii Bosmans & Pantini spec. nov. and Z. pseu- donigriceps Bosmans & Pantini spec. nov ., both from Sardinia, Z. montesacrense Bosmans spec. nov. and Z. valentii Bosmans, Loverre & Addante spec. nov ., both from Puglia, Z. valentii also occurs in Sicily. Zodarion sp., described from Greece in 2009, is the unknown female of Zodarion zorba Bosmans, 2009. Zodarion gracilitibiale Denis, 1934 is new for Italy. New records for 43 other European Zodarion species are presented. Keywords : distribution, faunistics, Greece, Italy, new species, Zodarion Zusammenfassung. Neue Arten und Neunachweise Ameisen fressender Spinnen aus dem mediterranen Europa (Araneae: Zoda- riidae). Folgende neue Zodarion -Arten werden aus Italien beschrieben: Zodarion pantaleonii Bosmans & Pantini spec. nov. und Z. pseu- donigriceps Bosmans & Pantini spec. nov. , beide von Sardinien, Z. montesacrense Bosmans spec. nov. und Z. valentii Bosmans, Loverre & Addante spec. nov. , beide aus Apulien, Z. valentii kommt auch auf Sizilien vor. Zodarion sp., 2009 aus Griechenland beschrieben, ist das unbekannte Weibchen von Zodarion zorba Bosmans, 2009. Zodarion gracilitibiale Denis, 1934 ist neu für Italien. Neue Funde 43 weiterer europäischer Zodarion -Arten werden präsentiert.
