A review of spiders of the genera Trachyzelotes Lohmander, 1944 and Marinarozelotes Ponomarev, gen. n. (Aranei: Gnaphosidae) from the southeast of the Russian Plain and the Caucasus

Abstract. The species composition and taxonomy of Trachyzelotes Lohmander, 1944 s. l. from the Russian Plain and the Caucasus (8 species) are reviewed. The new genus Marinarozelotes Ponomarev, gen. n. (type species: Melanophora barbata L. Koch, 1866) is described. This genus differs from other Zelotinae by the following characters of the copulative organs: large distally rounded base of the embolus; terminal apophysis is obliquely oriented or distally rounded; loop-like embolus; epigina with an M-shaped median ridge. New combinations are established: Marinarozelotes adriaticus (Caporiacco, 1951), comb. n., Marinarozelotes ansimensis (Seo, 2002), comb. n., Marinarozelotes baiyuensis (Xu, 1991), comb. n., Marinarozelotes barbatus (L. Koch, 1866), comb. n., Marinarozelotes bardiae (Caporiacco, 1928), comb. n., Marinarozelotes chybyndensis (Tuneva et Esyunin, 2002), comb. n., Marinarozelotes cumensis (Ponomarev, 1979), comb. n., Marinarozelotes fuscipes (L. Koch, 1866), comb. n., Marinarozelotes glossus (Strand, 1915), comb. n., Marinarozelotes holosericeus (Simon, 1878), comb. n., Marinarozelotes huberti (Platnick et Murphy, 1984), comb. n., Marinarozelotes jaxartensis (Kroneberg, 1875), comb. n., Marinarozelotes kulczynskii (Bösenberg, 1902), comb. n., Marinarozelotes lyonneti (Audouin, 1826), comb. n., Marinarozelotes malkini (Platnick et Murphy, 1984), comb. n., Marinarozelotes manytchensis (Ponomarev et Tsvetkov, 2006), comb. n., Marinarozelotes miniglossus (Levy, 2009), comb. n., Marinarozelotes minutus (Crespo, 2010), comb. n., Marinarozelotes mutabilis (Simon, 1878), comb. n., Marinarozelotes ravidus (L. Koch, 1875), comb. n., Marinarozelotes stubbsi (Platnick et Murphy, 1984), comb. n. The distribution patterns in the southeast of the Russian Plain and the Caucasus are analyzed for Trachyzelotes pedestris (C.L. Koch, 1837), Marinarozelotes adriaticus, M. barbatus, M. chybyndensis, M. cumensis, M. jaxartensis, M. malkini, M. manytchensis. A key to species of the genera Trachyzelotes and Marinarozelotes Ponomarev, gen. n. occurring in the studied region is given. Marinarozelotes lyonneti is excluded from the list of species of the region.
