A new species of Incestophantes Tanasevitch, 1992 from the high mountains of the Caucasus Major (Arachnida: Aranei: Linyphiidae)

Abstract

The new species, Incestophantes shetekaurii sp.n., is described from the high mountains of the Caucasus Major (Georgia, 2500 m a.s.l.). This new species is similar to the European-West Siberian I. crucifer (Menge, 1866) and to the Crimean I. australis Gnelitsa, 2009, but differs noticeably in the details of the genitalia in both sexes. The generic position of Bolyphantes lagodekhensis (Tanasevitch, 1990), and its differences to I. shetekaurii sp.n., is briefly discussed and illustrated.
