A new species of Xysticus C.L. Koch, 1835 (Aranei: Thomisidae) from South Siberia

Abstract

A new species, Xysticus lehtineni sp.n., is described from South Siberia on the basis of both sexes. It is closely related to X. baltistanus (Ca-poriacco, 1935) known from northern Pakistan to northeastern Asia. The two species clearly differ in size, abdominal pattern, spination and in the shape of the copulatory organs (male palp and female epigy-ne). Most of the records of X. baltistanus from Tuva refer to this new species.
