On synonymy of linyphiid spiders of the Russian fauna. 3 (Arachnida: Aranei: Linyphiidae)

摘要

The following new synonyms are established: Alioranus avanturus Andreeva et Ty-schchenko, 1970, syn.n. = A. chiardolae (di Capori-acco, 1935), comb.n. ex Gongylidiellum Simon, 1884; Gnathonarium sibirianum (Keyserling, 1886), syn.n. and G. columbianum(Emerton, 1923), syn.n. = G. taczanowskii (O. Pickard-Cambridge, 1873), non G. suppositum (Kulczynski, 1885); Pelecopsis steppen-sis Gnelitsa, 2008, syn.n. = P. laptevi Tanasevitch et Fet, 1986; Porrhomma kulczynskii Starqga, 1974, syn.n. = P. boreale (Banks, 1899). The synonymy of G. famelicum (Keyserling, 1886) with G. suppositum (Kulczynski, 1885) is reaffirmed. Abundant material of G. dentatum (Wider, 1834) is revised, some of the samples from the Russian Far East being actually referred to G. suppositum, but some others, from Kamchatka (the Geysers Valley), as well as from the continental parts of the Russian Far East and central Siberia, which combine the characters of both G. dentatum and G. suppositum, are probably hybrids between these similar taxa. All records of Вathyphantes similis Kulczynski, 1894 from Russia are misidentifi-cations and actually refer to B. gracilis (Blackwall, 1841). All Palaearctic records of Wabasso quaestio (Chamberlin, 1949) appear to represent W. replicatus (Holm,1950). Tapinocyba incerta Kulczynski, 1916, recorded by Tullgren [1955] in Sweden, actually refers to Tapinocyboides pygmaeus (Menge, 1869), thus the distributional pattern of this species, now Sibiro-cyba incerta, can be regarded as Siberian. Agyneta birulaioides Wunderlich, 1995 is being reported from Europe for the first time, due to its record in the steppe habitats of Kherson Area, Ukraine. Mecynar-gus minutipalpis Gnelitsa, 2011, from the Kalmyk Republic, and Tibioploides stigmosus (Xia et al., 2001), from the Kurile Islands, are new to the Russian fauna. Mecynargus longus (Kulczynski, 1882) is removed from the Russian list.
