A total of 732 spiders were collected, belonging to 21 families, 44 genera and 65 species. Altogether 14 species were discovered as new to the fauna of the Villányi Hills: Dipoena inornata (O. P.-Cambridge,1861); Alopecosa aculeata (Clerck, 1757); Alopecosa solitaria (Herman, 1876); Liocranum rutilans (Thorell, 1875); Gnaphosa lugubris (C. L. Koch, 1839); Zelotes aurantiacus Miller, 1967; Zelotes latreillei (Simon, 1878); Zelotes subterraneus (C. L. Koch, 1833); Zora nemoralis (Blackwall, 1861); Zora silvestris Kulczynski, 1897; Thanatus formicinus (Clerck, 1757); Xysticus sabulosus (Hahn, 1832); Xysticus ulmi (Hahn, 1832) and Talavera aequipes (O. P.-Cambridge, 1871 ). Thus, the number of spider species described from the Villányi Hills has increased to 201. The present paper includes a comprehensive species list of the Villányi Hills. Keywords: ground-dwelling spiders, Villányi Hills Introduction Spider faunal studies in the Villányi Hills were done by KOLOSVARY (1935) on Nagy-Hill, by LOKSA (1966) on Tenkes Hill, and by KOLOSVARY (1935), LOKSA (1966), KÉKESI and SEGESDI (1979), LOKSA (1984, 2002), SZINETÁR et al. (1998), SZINETÁR and LAJOS (2000) on Szársomlyó Hill. The first remarkable paper was published in 1935, in which KOLOSVARY (1935) summarized former spider faunal research in the region of Nagyharsány and Csamóta. A total of 10 species were listed. Xysticus embriki was described as a species new to science, and the presence of Nemesia pannonica in South Baranya was confirmed. In his analysis of Carpathian bush-forests Loksa (1966) presented 70 spider species to be present on Tenkes, Villányi Hills. KÉKESI and SEGESDI (1979), lead by Imre Loksa performed soil-zoological investigations on Szársomlyó Hill. In their thesis dissertation they listed 95 spider species (unpublished data). With specimens of Nemesia pannonica collected from Szársomlyó Hill, István Loksa (1984, 2002) carried out complex studies into the biology of the species. SZINETÁR et al. (1998) collected empty snail shells in 12 Hungarian localities to find out which spiders occupy them for the winter period. Altogether 5 species were reported from Szársomlyó Hill, of which Pellenes nigrociliatus was the absolutely dominating species. Based on the processing of material collected between 1995—2000 on Szársomlyó Hill, SZINETÁR and LAJOS (2000) reported 119 species, of which 4 were new to Hungarian fauna. Another species, Pelecopsis loksai (SZINETÁR and SAMU 2003), new to science, was also discovered in this collecting period. Fig. 1. Map of the study sites in the Villányi Hills
