New species and new records of spiders (Aranei) in the south of Russia

Abstract

Three new species of spiders from the families Gnaphosidae and Titanoecidae are described from the south of the European part of Russia (Astrakhan Region, Dagestan). Talanites alexeevi Ponomarev, sp. n. is characterized by the lamellar embolus, the narrow embolar base with the acute tooth-like outgrowth directed ventro-apically, the double-apex median apophysis, the epigyne with rounded fovea at the posterior margin and the anterior epigynal triangular-shaped hood with the wide arcuate posterior margin, the transverse oval contiguous spermathecae. Talanites thorelli Ponomarev, sp. n. has the following diagnostic characters: the tibia of the palp is with two processes; the embolar base is narrow, not wider than its distal part; the inner apical margin of the embolus is transformed into a long point; the double-apex median apophysis. Titanoeca caspia Ponomarev, sp. n. differs from congeners by the following characters: the tibia of the palp has a large, wide, complicated outgrowth pro-laterally, extending far beyond the lateral margin of the cymbium; tegulum with the large embolic pocket; the anterior margin of the embolic pocket bears a distinct tubercle; the process of the tegulum is large, retro-laterally shifted; the embolar haematodocha is large, protruding; the epigyne is with the narrow transverse slightly curved sclerotized plate; spermathecae are large, single, with short copulatory ducts. A new faunistic data are given for 14 species of spiders from the families Dictynidae, Gnaphosidae, Lycosidae, Mimetidae, Segestriidae, Theridiidae, Thomisidae. The following seven species of spiders are recorded for the fauna of Russia for the first time: Anagraphis ochracea (L. Koch, 1867), Gnaphosa haarlovi Denis, 1958, Zelotes fulvaster (Simon, 1878), Alopecosa kuntzi Denis, 1953, Alopecosa spasskyi Ponomarev, 2008, Lasaeolla dbari Kovblyuk, Marusik et Omelko, 2012, Ozyptila rigida (O. Pickard-Cambridge, 1872).
