Type. Holotype ♀ ( ZMMU) MONGOLIA, Khovd Aimag, Bumbat-Khairkhan-Bogd Mt. Range, Degnuult Mt. (47°12'N, 93°08'E), stony alpine meadow, 3000-3200 m, 24.06.2017 (A.A. Fomichev).

Etymology. The specific name is a patronym in honor of our friend and colleague, Recep Sulhi Özkütük, a well-known Turkish arachnologist and a partner of the second author in several expeditions to Anatolia.

Diagnosis. Mongolicosa ozkutuki sp. n. is most similar to M. uncia Fomichev & Marusik, 2017 and M. pseudoferruginea (Schenkel, 1936) . From the former species, it differs in having the gradually tapering lateral arms of the septal base (vs. thickened and rounded lateral edges of the septal base). The new species differs from M. pseudoferruginea in having the longer receptacles and the shorter anterior part of the fovea (Af) (cf Fig. 8d‒f and figs 218‒219 in Marusik et al. 2004).

Description. Female (holotype). Total length 9.7. Carapace 3.7 long, 3.0 wide. Coloration: carapace and sternum black. Labium, endites, chelicerae and palps dark brown. Legs dark brown with almost black Fe. Leg IV darker than others. Abdomen black. Spination of Leg I: Fe d1-1-1 p0-0-2 r0-1-1; Ti p1-0-0 r1-0-0 v2-2 -2-2; Mt p0- 1-0 r0-1-0 v2-2.

Epigyne as in Fig. 8d‒f . Anterior 2/3 of fovea triangle-shaped, posterior arms of plate almost touching each other. Septum abruptly widening posteriorly, its base almost diamond-shaped. Receptacles not well-separated from copulatory ducts (Cd), converging, head of receptacles spaced by one diameter in the intact epigyne ( Fig. 8d ).

Male. Unknown

Habitat. The single specimen of the new species was collected from the stony alpine meadow at 3000‒3200 m elevation ( Fig. 9d ).

Distribution. Known from the type locality only. Bumbat-Khairkhan-Bogd Mt. Range is located in Great Lake Depression, being separated from the main range of Mongolian Altai by the lowland steppe or semidesert territories. The neighboring Dzhargalant-Khairkhan Mt. Range, which is separated by only a few kilometers from the Bumbat-Khairkhan-Bogd Mt. Range, is the type locality of another Mongolicosa species ( M. uncia ) ( Fig. 10 ).
