The spider genus Tracbelas L. Koch, 1872 (Aranei: Corinnidae) in Russia

摘要

Three species of Trachelas are recorded from Russia: T. minor O. Pickard-Cambridge, 1872, T. japonicus Bosenberg & Strand, 1906 and T. tanasevitchi sp.n. (Bolshekhekhtsyrski Reserve Khabarovsk Prov., female). All species are described and illustrated.Trachelas L. Koch, 1872 is a fairly large genus with 86 species distributed almost worldwide [Plat-nick, 2010] and is apparently absent only from Australia and New Zealand. Recently, all Palaearctic representatives of this genus were revised in three independent studies [Bosselaers et al., 2009; Feng et al., 2009; Kovblyuk & Nadolny, 2009]. Bosselaers et al [2009] revised all eight species from the Mediterranean region and described one new species from the Iberian Peninsula. The paper of Feng et al. [2009] revised all Chinese members of the genus (six species altogether) and described two new species. Kovblyuk and Nadolny [2009] surveyed two species occurring in Crimea and Caucasus. The latter paper demonstrated that Trachelas was not a monophyleticgenus and described a new genus, Paratrachelas, for two species. Bosselaers et al (2009) also suggested that Trachelas is not a monophyletic genus. Taking into account new discoveries and transfers, the actual diversity of Trachelas is 87 species, 12 ofthem from the Palaearctic.
