Synaphosus sp.: Marusik & Logunov 1999: 240 (in part).
Types. MONGOLIA: Töv Aimag: holotype ♂ (ZMMU) and paratypes 5♂ 3♀ (ZMMU) Bayankhangai Somon, 47°20'N, 105°24'E, 1200 m, screes and cliffs in canyon, 21 – 25.05.1997 (YM). Ömnögovi Aimag: 3♂ 2♀ (ZMMU) Bayandalai Somon, Zoolen-Uul Mt. Range, 43°21'N, 103°11'E, 1700 m, pitfall traps and sweeping Oxytropis glabra, 27 – 30.05.1997 (YM); 3♀ (ZMMU) Noyon Somon, Noyon-Uul Mt. Range, 43°01.73'N, 102°05.90'E, 1900 m, vadi-small canyon in desert under stones, 30 – 31.05.1997 (YM). Bayankhongor Aimag: 1♂ 1♀ (ZMMU) Bayanlig Somon, Bor-Tolgoi, 44°06'N, 100°56'E, 1400 m, pitfall traps in desert and close to bushes, sweeping/ shaking bushes (Amygdalus, Caragana, Zygophyllum), 2–4.06.1997 (YM).
Etymology. The specific name is a patronym in honour of Vladimir I. Ovtsharenko (New York, USA), a well known expert in Gnaphosidae who revised the genus.
Diagnosis. The new species belongs to the syntheticus -group and most similar to S. taukum and S. saidovi sp. n. It differs from S. taukum by partially fused hoods of the pocket (entirely fused in S. taukum), oval shaped and vertically directed copulatory openings (slanting, furrow (elongate oval) like copulatory openings in S. taukum) and median loops of copulatory ducts touching each other (spaced in S. taukum) (cf. Figs 22‒24 and figs 43‒44 in Ovtsharenko et al. [1994]). Synaphosus ovtsharenkoi sp. n. well differs from S. saidovi sp. n. by pale colouration (cf. Figs 1 and 5) and copulatory openings located over pocket.

Coloration. Carapace and sternum yellow-brown. Chelicerae, maxillae and labium light-brown. Legs and palps yellow-brown, tibiae-tarsi darker than other segments.

Size variation. Males vary from 2.1 to 3.05 in the body length, carapace 1.1–1.33 long and 0.8–0.98 wide (n=10). Females vary from 2.6 to 3.4 in the body length, carapace 1.2–1.53 long and 0.83–1.08 wide (n=9). Distribution. Southwestern and Central Mongolia (Fig. 51). It is the easternmost species of the genus in Central Asia.
