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.

Description.

Male. Total length 8.5. Carapace: 4.05 long, 3.05 wide. Coloration: carapace and legs brown. Chelicerae dark brown. Sternum, labium and maxillae brown. Abdomen grayish-brown. Spinnerets light brown. Spination: I: Fe d1-1-0, p0-1-1; Ti v0-1-1; Mt v2-1-0. II: Fe d1-1-0, p0-1-1; Ti p1-0-0, v1-1-2; Mt v2-1-0. III: Fe d1-1-0, p0-1-1, r0-1-1; Pt p1, r1; Ti d1-0-0, p2-2-0, r2-1-1, v2-2-2; Mt d0-2-0, p 1-1-0, r1-1-0, v2-2-0. IV: Fe d1-1-0, p0-1-1, r0-1-1; Pt r1; Ti p2-2-0, r2-1-1, v2-2-2; Mt d0-2-0, p1-1-0, r1-1-0, v2-2-0. Leg article length. I: 3.15+1.7+2.65+2.3+1.65. II: 3.0+1.6+2.4+2.3+1.65.

Palp as in Figs 1-5, tibial apophysis relatively short (shorter than tibia) with sharply pointed tip bent downward; median apophysis relatively small, as long as tibia; embolus unmodified, whip like, base of embolus located on posterior 1/3 of bulbus; upper part of embolic base with beak-shaped spine; prolateral edge of embolus serrated.

Female unknown.
