ABSTRACT. Five new synonyms are established for the Russian fauna of Linyphiidae: Agyneta bialata (Tao, Li et Zhu, 1995), syn.n. = A. birulai (Kulczyński, 1908); Agyneta parasaxatilis Marusik, Hippa et Koponen, 1996, syn.n. = A. pseudosaxatilis Tanasevitch, 1984; Diplocephalus cristatus angusticeps Holm, 1973, syn.n. = D. c. cristatus (Blackwall, 1833); Minyrioloides trifrons affinis (Schenkel, 1930), syn.n. = M. trifrons (O. Pickard-Cambridge, 1863); Lepthyphantes tes Marusik, Hippa et Koponen, 1996, syn.n. = Oryphantes geminus (Tanasevitch, 1982). The synonymy of Bathyphantes biscapus Kulczyński, 1926 with B. humilis (L. Koch, 1879), B. simillimus (L. Koch, 1879) with B. eumenis (L. Koch, 1879) and B. insulanus Holm, 1960 with B. pogonias Kulczyński, 1885, are confirmed. The earlier synonymy of B. biscapus and B. keeni (Emerton, 1917), as well as of B. castor Chamberlin, 1925 and B. pogonias Kulczyński 1885, are rejected. The female of B. jeniseicus Eskov, 1979 is shown to be that of B. eumenis. The female of B. jeniseicus and the male of B. humilis are described for the first time. All the records of B. iviei Holm, 1970 and B. keeni from Russia are based on misidentifications; thus both species are to be excluded from the Russian and Palaearctic faunas. Numerous previous misidentifications of many species are corrected. Caviphantes pseudosaxetorum Wunderlich, 1979 is recorded from the Russian fauna for the first time; Gongylidiellum orduense Wunderlich, 1995, Mecynargus foveatus (Dahl, 1912), Russocampus polchaninovae Tanasevitch, 2004 and Silometopus incurvatus (O. Pickard-Cambridge, 1873) are added to the Caucasian fauna; on the contrary, G. murcidum Simon, 1884 are to be excluded from the Caucasian fauna. The record of Minyrioloides trifrons (O. Pickard-Cambridge, 1863) from the Tien-Shang Mts actually refers to M. maritimum Crocker et Parker, 1970; the latter species early known as W-European is hence a new record to Central Asia.
