Two new Stemonyphantes Menge, 1866 from Kazakhstan (Aranei: Linyphiidae: Stemonyphantinae)

摘要

Two new species of the linyphiid spider genus Stemonyphantes Menge, 1866 are described: S. karatau sp.n. from the West Tien-Shang Mts, Kazakhstan, and S. taiganoides sp.n. from eastern Kazakhstan and the southern part of western Siberia. S. karatau sp.n. is similar to S. curvipes Tanasevitch, 1989, known from the northern Tien-Shang Mts; S. taiganoides sp.n. is close to the southern Siberian S. taiganus (Ermolajev, 1930). The latter species is recorded for the first time since its description, with detailed figures of the genitalia of both sexes provided.
