Dasypolia (Dasypolia) volynkini G. Ronkay, L. Ronkay, Gyulai & Pekarsky, 2014 , Fibigeriana Supplement 2: 146, pl. 29, figs 5, 6, gen. fig. 7 (Type locality: " Kazakhstan, Sary-Su river, 200 m, 230 km E Kzyl-Orda").

Type material examined: Paratypes: 2 females, SE Kazakhstan, Alma-Ata area, 3 km SE Arkharly Pass, 1070 m, 44º13'36.33'' N, 77º43'53.64'' E, 2–3.x.2010, leg. Taranov B.T. & Egorov P.V., slide AV0963f Volynkin (Coll. A. Volynkin, Barnaul). Additional material examined: 1 male, 12–13.iv.2014, SE Kazakhstan, Almaty area, 10 km E of Kerbulak, Sholak Mts., h= 800 m, 43°55'7.66"N, 77°47'18.45"E, Egorov P.V. & Rakhimov R.D. leg., slide AV 1332m Volynkin (Coll. A. Volynkin, Barnaul); 1 male, 19–20.iv.2014, SE Kazakhstan, Almaty area, Zhetyzhol Mts., 9 km NW of Ulken-Sulutor (old Krasnogorka) village, h= 1250 m, 43°20'32.70"N, 75°06'44.40"E, Egorov P.V. & Rakhimov R.D. leg. (Coll. A. Volynkin, Barnaul).

Diagnosis of male. Male wingspan 24–25 mm. The male of D. volynkini ( Fig. 2 ) has the ground colour and the wing pattern same as in the female, but male antennae are serrate and fasciculate. The male genitalia of D. volynkini ( Fig. 6 ) are close to D. minuta ( Figs 1, 5 ) and Dasypolia akkeregeshena Ronkay, Ronkay, Gyulai & Pekarsky, 2014 ( Figs 3, 7 ) but differ from D. minuta by the shorter and broader uncus, the larger dorso-medial process of juxta, the more rounded vinculum, narrower and apically more rounded harpe, and the medially broader vesica; from D. akkeregeshena differ by the somewhat longer dorso-medial process of juxta, the more rounded vinculum, the basally broader valva, the terminally narrower harpe, the differently shaped dorso-medial sclerotized plate of the distal segment of aedagus, and the medially broader vesica. From the third species of the species-complex, Dasypolia zolotuhini Ronkay, Ronkay, Gyulai & Pekarsky, 2014 ( Figs 4, 8 ) differ clearly by the apically broader uncus, the flattened and broader harpe, the reduced costal extension, the differently shaped dorso-medial sclerotized plate of the distal segment of aedagus, and the larger and stronger sclerotised carinal plate.

Description of male genitalia ( Fig. 6 ). Uncus moderately long, broad, obtuse apically; tegumen short, penicular lobes moderately broad; vinculum short, U-shape. Juxta shield-like, with two narrow latero-apical and one large dorsomedial processes. Valva elongated, basally broad, distally much narrowed, apically rounded; sacculus broad, setose; costa broad and strongly sclerotised, costal extention broad and very short; clasper moderately broad, curved; harpe moderately broad, curved, apically club-like broadened. Aedeagus elongated, narrow; carinal plate strongly sclerotised, with several thorns; vesica membranous, tubular, curved ventrally, broadened medially.

Bionomics and distribution. The species is known from southern Kazakhstan (the type-locality, Sary-Su river valley) and several localities in southeastern Kazakhstan (northeastern part of the Tien Shan mountain massif). As well as other members of the D. minuta species-complex ( Ronkay et al. 2014), D. volynkini has overwintering males (the both known males were collected in mid April), which is unusual for the nominate subgenus. In southeastern Kazakhstan all specimens were collected at low altitudes (800–1250 m.). The species inhabits dry low mountains, in Arkharly pass the paratypes were collected in habitat with predominance of Spiraea , Ephedra , Atraphaxis and Prunus shrubs, and various herbs, e. g., Ferula and Poaceae ; in Sholak mountains ( Fig. 9 ) the habitat dominated by Salsola , Atraphaxis and Prunus shrubs; in Zhetyzhol mountains ( Fig. 10 ) the habitat dominated by Rosa shrubs and various grasses ( Poaceae , etc.).
