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). GoogleMaps

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 View FIGURE 8 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 View FIGURE 8 . 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 View FIGURE 8 ).

Male. Unknown

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

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 View FIGURE 10 ).
