Material.

MONGOLIA, Khovd Aimag: holotype ♂ (ISEA), Arshantyn-Nuruu Mountain Range, 46°16'46"N, 91°16'53"E, 1560 m, mountain stony steppe, under stone, 14.05.2012 (A.A. Fomichev).

Etymology.

The specific name derived from Khovd Aimag, adjective.

Diagnosis.

The new species is related to Gnaphosa esyunini sp. n., Gnaphosa jucunda Thorell, 1875 and Gnaphosa ustyuzhanini by having a strong spine in the embolic base and a filamentous embolus with a serrated prolateral edge. From Gnaphosa ustyuzhanini (Figs 17-18) and Gnaphosa jucunda it can be distinguished by the prolaterally directed strong embolic spine. In addition Gnaphosa jucunda has a thick, not filamentous embolus (cf. Ponomarev and Kovblyuk 2009: figs 19-20) and smaller median apophysis. Gnaphosa khovdensis sp. n. differs from Gnaphosa esyunini sp. n. by the smaller embolic spine located on the retrolateral side of the embolus and smaller body size.
