( Figs 1-4 )

Type material: Holotype, male ( ZISP, gen.pr. Nr. 1929), TAJIKISTAN, Khozratishoh Mt. Range , Shuroabad distr., 8 km ESE Shuroabad, Tiryay Mts., 1635 m, 37°49'20"N, 70°07'40"E, 15.vii.2018, O. Pak . Paratype, 1 female ( ZISP, gen.pr. Nr. 1930), same locality and data .

External characters

Wingspan 19 mm. Head covered with clinging grey scales, forehead tapered; labial palpi light-grey, short, directed upwards. Antennae more or less ringed with brown-white scales, shortly ciliated. Thorax and tegulae covered with clinging light-grey scales. Fore wing grey-brown with four dark spots of scales along costal edge and medially. Hind wing grey unicolorous.

Male genitalia

Valves symmetric, elongated, narrow-oval, widened in medium part, apically narrow; costal arms of equal length, with finger-like processes on apices. Uncus narrow, straight. Tegumen wide. Sternum VIII with Vshaped notch, forming two equal prongs basally wide, distally narrow. Aedeagus arched, with process in medium part.

Female genitalia

Papillae anales narrow-triangle. Posterior apophyses thin, straight, twice longer than papillae anales. Anterior apophyses short, wide. Lamina vaginalis consists of two wide lobes, forming narrow notch in medium part. Antrum narrow, tubulate, strongly sclerotized, ductus bursae short, slightly wider than antrum; bursa copulatrix poorly sclerotized, oval. Sternum VII with auricular appendages laterally.

Differential diagnosis. In the male genitalia, in the shape of the tegumen and uncus and in the general structure of the valves and aedeagus, the new species is close to A. iranica , but clearly differs in the wider valve and another structure of the processes on the costal edge of the valves. Moreover, in the new species the aedeagus is more curved and has a process in the medium part, while in A. iranica it is less curved and has no similar process. The prongs on sternum VIII in the new species are of equal length, while in A. iranica they are different in length and shape. In the female genitalia, in the shape of the lamina vaginalis, auricular appendages on the lateral sides of sternum VII and presence of the anterior apophyses, the new species is close to A. falkovitshi Zagulajev, 1986 , but reliably differs in the narrow tubulate antrum.

Flight period. July.

Distribution. Tajikistan (Khozratishoh Mountains Range).

Etymology. The species is named after the Ukrainian entomologist Oleg Pak who collected the new species in Tajikistan.
