| Summary: | Dzhungarocosa omelkoi sp. n. Figs 5–8, 16–18, 25–27, 35–38, 49–51, 57–61, 69–71, 77–80 Types. Holotype ♂ (ISEA, 001.7316) and paratypes 1♂ 3♀ (ISEA, 001.7317) KAZAKHSTAN, Almaty Region, watershed of Ermenesai and Koksai Rivers (44°43’N, 79°19’E), stony alpine meadow with screes, 2900–3000 m, 3.07.2016 (A.A. Fomichev). Paratypes: 3♂ 2♀ (ZMMU) same locality (44°43’N, 79°18’E), mountain stony tundra with screes, 3000–3100 m, 3.07.2016 (A.A. Fomichev). Etymology. The specific name is a patronym in honour of our friend and colleague Mikhail M. Omelko (Vladivostok, Russia), for his noteworthy contribution to the study of Acantholycosa and related genera. Diagnosis. The new species differs from the sibling D. ballarini sp. n. by smaller size and shape of copulatory organs. Males of D. omelkoi sp. n. have no digitiform anterior paleal process, present in D. ballarini sp. n. (Figs 47, 50). The two species also differ by the shape of terminal apophysis, which is more massive in D. omelkoi sp. n. (Figs 46–48, 49–51). Females of the two sibling species differ by the proportion of septal base, which is as long as wide in D. omelkoi sp. n. vs wider than long in D. ballarini sp. n. (Figs 57, 62); by the distance between septal pockets (touching each other in D. omelkoi sp. n. vs spaced in D. ballarini sp. n., Figs 60, 65) and the shape of posterior part of septal base (Figs 61, 66). Description. Male. Total length 8.7. Carapace: 4.0 long, 3.15 wide. Colouration (Fig. 5): carapace, sternum and labium black. Clypeus yellow with a black stripe on its lower edge. Chelicerae black with yellow stripes. Endites brown-gray with a yellow spot on the inner side. Palps: Fe, Ti and cymbium black, Pt yellow. Legs: I and II: Fe dark-gray, yellow apically, Pt–Ta yellow; III and IV yellow-gray. Abdomen black, without any pattern. Leg I joints: 3.65+1.6+3.55+3.85+1.65. Spination of leg I: Fe: d1-1-1 p0-1-3 r0-1-1; 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 16–18, 25–27, 35–38, 49–51. ... |
