Ivanova (slide # AN104; Zoological Institute , Sankt-Petersburg , Russia ). Description . Male. Antenna twice shorter than fore wing, bipectinate, setae 2.5−3 times longer than antenna stem in diameter (in medium third). Length of fore wing 11 mm . Fore wing light-yellow, with ochre spot at apex of discal cell, costal margin of wing with dense sputtering of ochre scales, frame thin, light-brown, with small light-brown spots at veins, fringe mottled (ochre at veins and light between veins). Hind wing ochre-yellow without pattern. Figures 1−8. Dyspessa , adult males, and male genitalia: 1. D. igoripljushtchi sp. nov. , holotype; 2.

D. sochivkoi , male genitalia (slide GenitalPräparat Heterocera 28.262). Male genitalia. Uncus long, poorly narrowing to apex, apex sclerotized; gnathos arms of medium length; gnathos poorly structured; valve poorly sclerotized in distal third, apically semicircular, costal margin of valve (on border between medium and distal third) with very developed bump with uneven surface (height of bump slightly exceeds width of valve); transtilla process triangle, apically blunt; juxta tiny, with two small leaf-like lateral processes; saccus semicircular, of medium size; phallus equal to valve in length, thin, poorly curved on border between proximal and medium third, narrowing to apex, vesica aperture in dorso-apical position, about half of phallus in length, vesica without cornuti. Female unknown. Diagnosis . The new species is most close to D. curta ( Figs 5−6 ) and D. sochivkoi ( Figs 7−8 ), from which it differs in the light-coloured wings and the distinctive bump on the costal margin of the valve. Distribution . Tajikistan , Khozratishokh Range. Etymology . The new species is named after Oleg Pak, a well-known explorer of Lepidoptera fauna of Central Asia and Afghanistan .
