On a new Eurasian species of Dictyna Sundevall, 1833 (Aranei: Dictynidae), with taxonomic notes on poorly known Palaearctic Dictyna species

A new species Dictyna sinuata sp.n. (male) is described from the steppe zone of Orenburg Area, Russia. This species belongs to the arundinacea species group and is closely related to the North American D. bostoniensis Emerton, 1888, from which it can readily be distinguished by the shape of conductor, the smaller body size, and the body coloration. New combinations are proposed for five species names (all ex. Dictyna): Nigma albida (O. Pickard-Cambridge, 1885) comb.n., Sudesna flavipes (Hu, 2001) comb.n., Bannaella lhasana (Hu, 2001) comb.n., Nigma nangquianensis (Hu, 2001) comb.n. and Brigittea varians (Spassky, 1952) comb.n. Dictyna xinjiangensis Song, Wang et Yang, 1985, syn.n., is synonymized with Brigittea varians (Spassky, 1952). The earlier synonymy is confirmed: Dictyna felis Bosenberg et Strand, 1906 = Dictyna paitaensis Schenkel, 1953 syn.rev. Four species of Dictyna known from the females are to be treated as insertae sedis: "Dictyna" linzhiensis Hu, 2001, "Dictyna" namulinensis Hu, 2001, "Dictyna" tristis Spassky, 1952 and "Dictyna" zhangmuensis Hu, 2001.
