Description. FEMALE (holotype). Body, including gnathosoma, 285 long (335 in paratype), 160 wide (180). Propodonotal shield with widely rounded posterior margin, length 69 (50), maximum width 56 (52). Setae si 36 long (30), subequal to se 30 long (35). Distance se–se 69 (60), about 4.5–5 times greater than si–si, 15 (11). Bursa copulatrix opening dorsal. Sternum 16 long (18). Posterior projections of coxal fields I distinctly developed, about 10 long, 17 wide. Distance between distal ends of apodemes II 18 (22). Two pairs of weakly developed folds present ventrally on propodosoma posterior to coxal fields II. Distance 4a–4a 29 (20), subequal or 1.9 times longer than ps3–ps3, 15 (18). Alveoli of setae h1 and h3 absent. Legs III and IV subequal in length, about 115 and 130 long, respectively (excluding pretarsus). Setae cG I filiform, 9–10 long, cG II microspines, about 3 long. Setal lengths: 1a 13 (10), c3 14 (14), cp 34 (28), h2 145 (130), vF I 21 (20), vF II 35 (30), mG I–II 27 (29), gTI–II about 4, solenidia ϕI–II 9 (8), ω 1 I–II 8 (10).

MALE (paratype). Body, including gnathosoma, 280 long, 145 wide. Propodonotum as in female. Propodonotal shield 50 long, 53 maximum wide. Setae si 35 long, subequal to se, 30 long. Distance se–se 52, 5–6 times greater than si–si, 9. Sternum 15 long. Posterior projections of coxal fields I distinctly developed, 9 long, 17 wide. Distance between distal ends of apodemes II 17. Two pairs ofweakly developed folds present ventrally on propodosoma posterior to coxal fields II. Posterior end of aedeagus situated at level of setae g. Length and width of postgenital shield subequal, about 22. Distance g–g 13, about 3 times greater than ps3– ps3, 4. Alveoli of setae h1 and h3 absent. Legs III and IV subequal in length, about 110 and 125 long, respectively (excluding pretarsus). Setae cG I filiform, 9 long, cG II microspines, about 2 long. Setal lengths: 1a about 13, c3 13, cp 26, h2 125, vF I 18, vF II 19, mG I 22, mG II 25, gTI–II about 3, solenidia ϕI–II about 9, ω 1 I–II about 10.

Type material examined. Female holotype ( SIZ 52 /66.8), female ( SIZ 50 /66.8) and male ( SIZ 50 /66.8.1) paratypes ex Alticola argentatus (Severtzov) (Critetidae), KIRGHIZIA: Kuvaki pass, Kok-Tundy tract, 40°50'N, 73°37'E, 2200 m, date unknown, coll. A. Kharadov.

Type deposition. Holotype and both paratypes are deposited in SIZ.

Host range and distribution. This species is known only from the type host, Alticola argentatus, from Kirghizia .

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.

Remarks. This new species is closely related to Y. ascanicus . In both sexes of these two species setae cG I are filiform, setae cp are more than 1.5 times longer than c3, the posterior projections of coxal fields I are about 1.9 times wider than long; in males the basal part of the aedeagus is situated at the level of setae 4a. It differs from Y. ascanicus by the following characters. In both sexes of Y. alticola setae cp are 2 times longer than c3. In both sexes of Y. ascanicus setae cp are 1.6–1.8 times longer than c3.
