ABSTRACT. Records from Orenburg Region are provided for 100 spider species. Eight species: Pachygnatha clerckoides Wunderlich, 1984, Alopecosa psammophila Buchar, 2001, Coelotes turkestanicus Ovtchinnikov, 1999, Dictyna szaboi Chyzer, 1891, Zodariellum nenilini (Eskov in Eskov et Marusik, 1995), Thanatus imbecillus L. Koch, 1878, T. mikhailovi Logunov, 1996, and Chalcoscirtus paraansobicus Marusik, 1990, are reported from Russia for the first time; the 17 other species represent new records to the Urals. Two species, Atypus muralis Bertkau, 1890, and Latrodectus tredecimguttatus (Rossi, 1790), are confirmed as present on the basis of newly collected material. The females of Drassodes rostratus Esyunin et Tuneva, 2002, and Xysticus ulkan Marusik et Logunov, 1990, are described for the first time. Alopecosa trabalis (Clerck, 1758) is redescribed on the basis of fresh material from the South Urals. Pardosa troitskensis Esyunin, 1996, is synonymised with P. maisa Hippa et Mannila, 1982. The taxonomic status of "Pardosa" nebulosa (Thorell, 1872) is discussed. Some misidentifications in the previously published lists of Orenburg spiders are corrected.
