Abstract

A diagnosis and an illustrated description of Mongolicosa uvs Esyunin et Ustinova sp. n. from the Uvs Province of Mongolia is provided, based on both sexes. The new species belongs to the pseudoferruginea group and appears to be especially similar to M. glupovi Marusik, Azarkina et Koponen 2004, yet differing in having a wide septal stem of the epigyne and an elongated terminal apophysis of the male palp.
