Figs 1–4 , 13–15 , 22–24 , 31–34 , 43–45 , 52–56 , 67–68 , 75, 79–80

Types. Holotype ♂ (ISEA, 001.7314) and paratypes 4♂ 2♀ (ISEA, 0 0 1.7315, 001.7952) KAZAKHSTAN, Almaty Region, upper reaches of Aksu River, near Akambai River origins (45°03’N, 79°40’E), scree, 3000–3300 m, 23.06.2016 (A.A. Fomichev).

Etymology. The specific name is a patronym in honour of our colleague Zhi-Sheng Zhang (Chongqing, China), a well known expert in taxonomy of Lycosidae and other spider families.

Diagnosis. The new species differs from congeners by the shape of copulatory organs. Males of D. zhishengi sp. n. have triangular anterior arm of tegular apophysis ( Fig. 15 , claw-like in other species) and straight embolus ( Fig. 24 , bent in other congeners). Females differ from the congeners by the wide septal stem, wider than posterior part of septum ( Fig. 52 , stem much thinner than the base of septum in congeners).

Description. Male (holotype). Total length 8.1. Carapace: 4.0 long, 3.3 wide. Colouration ( Fig. 1 ): carapace black with elongated yellow spot around the fovea. Clypeus yellow, with black stripe on its lower edge. Chelicerae black with yellow stripes. Sternum and labium black. Endites brown-gray with yellow spot on the inner side. Palps: Fe and Pt—black with yellow spots, Ti and cymbium black. Legs bright-yellow with black rings. Abdomen black with indistinct pattern formed by gray hairs. Leg I joints: 3.75+1.65+3.5+3.9+1.7. Spination of leg I: Fe: d1-1-1 p0- 1-2 r2-0-1; Pt: d1-1 r1-0; Ti: d1-0-1 p2-0-0 r1-0-0 pv4 rv5; Mt: p1-1-0 r1-1-0 v2-2 -0.

Palp as in Figs 13–15 , 22–24 , 31–34 , 43–45 . Tegular apophysis with almost triangular anterior arm (Aa) ( Fig. 15 ); paleal processes triangular, posterior process (Pp) not subdivided in 2 parts ( Fig. 43 ); conductor (Co) sharply pointed ( Fig. 45 ); terminal apophysis (Ta) with triangular (spine-like) anterior (dorsal) outgrowth, posterior outgrowth larger, rounded on the tip ( Fig. 45 ); embolus straight ( Fig. 43 ).

Female. Total length 10.4. Carapace: 4.7 long, 3.9 wide. Colouration ( Fig. 2 ): carapace black with elongated yellow spot around the fovea and yellow stripes near edges. Clypeus, sternum, labium and endites like in male. Chelicerae yellow basally and dark-brown apically. Legs and palps black with yellow rings. Abdomen black with indistinct pattern formed by golden hairs dorsally, yellowish-gray ventrally. Leg I joints: 4.35+2.0+3.95+3.85+1.75. Spination of leg I: Fe: d1-1-1 p0-1-2 r0-1-1; Pt: d1-1 r1-0; Ti: d1-0-1 p1-0-0 r1-0-0 pv4 rv5; Mt: p0-1-0 r0-1-0 v2-2 -0.

Epigyne as in Figs 52–56 , 67–68 . Stem of septum wider than posterior 1/3 of septum, stem with two ridges; septal pockets located almost in middle part of septum, pockets separated by 2/3 of pocket width. Head of receptacles directed anteriorly, not converging.

Size variation. Males vary from 7.9 to 8.9 in body length, carapace 4.0–4.3 long and 3.1–3.45 wide (n=5). Females vary from 10.2 to 10.4 in body length, carapace 4.4–4.7 long and 3.65–3.9 wide (n=2). Distribution. Type locality only ( Figs 79–80 ).
