Figs 9–12 , 19–21 , 28–30 , 39–42 , 46–48 , 62–66 , 72–74 , 76, 79–80

Types. Holotype ♂ (ISEA, 001.7318) and paratypes 2♀ (ISEA, 0 0 1.7319, 001.7953): KAZAKHSTAN, Almaty Region, Burkhansartau Mt. Range (44°34’N, 79°57’E), scree, 3000 m, 27.06.2016. (A.A. Fomichev).

Etymology. The specific name is a patronym in honour of our friend and colleague Francesco Ballarin (Beijing, China), for his significant contribution to the taxonomy of Pardosinae in Central Palaearctic.

Diagnosis. Dzhungarocosa ballarini sp. n. differs from the sibling D. omelkoi sp. n. by the larger size and shape of copulatory organs. Male of this species has a digitiform paleal process, which is lacking in D. omelkoi sp. n., and less massive terminal apophysis ( Figs 46–48, 49–51 ). Females of the two species differ by the shape of septal base (wider than long in D. ballarini sp. n. vs as long as wide in D. omelkoi sp. n.) and spacing of septal pockets (spaced in D. ballarini sp. n. vs touching in D. omelkoi sp. n., Figs 65 , 74 and 60 , 71 respectively).

Description. Male (holotype). Total length 9.5. Carapace: 4.8 long, 3.9 wide. Colouration ( Fig. 9 ): carapace, sternum and labium black. Clypeus yellow with black stripe on its lower edge. Chelicerae dark-gray with yellow stripes. Endites yellow-gray with a yellow spot on the inner side. Palps: Fe, Ti and cymbium black, Pt yellow. Legs: all femora black with yellow spots, Pt–Ta I yellow, II–IV yellow-gray. Abdomen black with unclear pattern formed by gray hairs dorsally. Leg I joints: 4.45+2.0+4.35+4.45+1.85. Spination of leg I: Fe: d1-1-1 p0-0-2 r2-0-1; Pt: d1- 1 p1-0 r1-0; Ti: d1-0-1 p1-0-0 r1-0-0 pv6 rv6; Mt: p1-1-0 r1-1-0 v2-2 -0.

Palp as in Figs 19–21 , 28–30 , 39–42 , 46–48 . Tegular apophysis with long, claw-like anterior arm; anterior paleal process (Ap) digitiform; posterior process (Pp) triangular, its retrolateral part ridge-like; terminal apophysis broad (in anterior view) with outgrowths equal in size; embolus smoothly bent.

Female. Total length 8.6. Carapace: 4.5 long, 3.55 wide. Colouration ( Fig. 10 ): carapace dark-brown, almost black with a yellow spot in front of the fovea. Clypeus yellow, with a gray triangular spot in the middle. Chelicerae yellowish-brown. Sternum dark-gray with wide yellow edge. Labium and endites yellowish-gray. Legs and palps yellow with gray rings. Abdomen dorsally dark-gray with lighter cardiac mark, cream-colored ventrally. Leg I joints: 4.05+1.9+3.8+3.45+1.5. Spination of leg I: Fe: d1-1-1 p0-1-2 r0-1-1; Pt: d1-1; Ti: d1-0-1 p1-0-0 r1-0-0 pv6 rv6; Mt: p1-1-0 r1-1-0 v2-1 -0.

Epigyne as in Figs 62–66 , 72–74 . Septal stem thin, base of septum wider than long, pockets spaced ( Figs 65 , 74 ); base of septum wider than long in posterior view ( Fig. 66 ); head of receptacles slightly converging.

Size variation. Females vary from 8.6 to 10.5 in body length, carapace 4.5 long and 3.55–3.65 wide (n=2).

Distribution. Type locality only ( Figs 79–80 ).
