description
Description. Female (holotype). Total length 6.9. Carapace 3.5 long, 2.85 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 d 1 - 1 - 1 p 0 - 0 - 2 r 0 - 1 - 1; Ti p 1 - 0 - 0 r 1 - 0 - 0 v 2 - 2 - 2 - 2; Mt p 0 - 1 - 0 r 0 - 1 - 0 v 2 - 2. Epigyne as in Fig. 8 g ‒ i. Fovea pear-shaped, its anterior part as long as the posterior one, the posterior arms of plate touching each other. Septum abruptly widened in the posterior part of fovea, forming a diamond-shaped base. Receptacles (Re) well distinguishable from the copulatory ducts (Cd), converging, head of receptacles spaced by one diameter in the intact epigyne (Fig. 8 g). Male. Unknown. Size variation. Females vary from 6.6 to 6.9 in body length, carapace 3.3 ‒ 3.5 long, 2.7 ‒ 2.85 wide (n = 3). Habitat. The new species inhabits the humid and very cold mountain stony tundra and moraines at elevations of 3300 ‒ 3770 m (Fig. 9 e ‒ f).
description
Types. Holotype ♀ (ZMMU) MONGOLIA, Bayan-Ölgii Aimag, Cengel-Khairkhan-Nuruu Mt. Range, Cengel- Khairkhan Mt. (48 ° 38 ' 36 " N, 89 ° 10 ' 22 " E), moraine, 3300 ‒ 3400 m, 15.07.2017 (A. A. Fomichev). Paratypes: 2 ♀ (ZMMU) same locality (48 ° 39 ' N, 89 ° 10 ' E), mountain stony tundra, 3620 - 3770 m, 15.07.2017 (A. A. Fomichev).
diagnosis
Diagnosis. Mongolicosa cherepanovi sp. n. is most similar to M. glupovi Marusik, Azarkina & Koponen, 2004 in the shape of the epigyne septum. The new species differs from M. glupovi in having the pear-shaped fovea, the longer anterior part of the fovea and strongly converging receptacles vs. the almost round fovea, with a very short anterior part (as long as the anterior pocket width) and almost parallel receptacles (cf. Fig. 8 g ‒ i and figs 208 ‒ 212 in Marusik et al. 2004).
distribution
Distribution. Known from the type locality only. Cengel-Khairkhan-Nuruu Mt. Range is one of the highest mountain ranges of the Mongolian Altai (Fig. 10).
etymology
Etymology. The specific name is a patronym in honor of Mr Alexander Cherepanov, a friend of the senior author and a driver in several expeditions to Mongolia, and who brought the 2017 expedition to the type locality of this species.
