 Material. Holotype, male, Kirgizia, Tash-Kumyr, 600 m, 19.vi.2004, leg. M. Danilevsky; slide AN 120 (ZISP).   
Paratypes. 9 males, 5 females, same locality and data (ZISP, RYB); 1 male, Kirgizia, Ketmen-Tyube, 800 m, 17.vi.2004, leg. M. Danilevsky (RYB); 5 females, Kyrgyzstan, Toktogul Dam, 41°44ʹN 72°51ʹE, 915 m, 28.vi.2008, P. Ustjuzhanin (RYB); 1 male, S. Kirg. [izia], Fergana Mt. R., Bekechal Ravine, on light, 950 m, 41°32ʹN 72°30ʹE, 4.vi.2008, leg. D. Milko (IBBK).  
 Description. Male. Length of fore wing 9 mm in holotype, 8.5− 10 mm in paratypes. Antenna slightly longer than half of fore wing in length, bipectinate, setae 2.5 times longer than antenna stem in diameter. Thorax and abdomen densely covered with light-brown scales. Fore wing brown, with sputtering of light-brown scales basally and along costal edge, without pattern, border thin, ocher, fringe brown. Hind wing brown, without pattern, border thin, ocher, fringe brown.   
Male genitalia. Uncus relatively short, tapered, slightly narrowing from base to apex, apex semicircular; gnathos arms thin, of medium length; gnathos small; valve narrow, apical third membranous, apex lanceolate,costal edge of valve (on border between medium and distal thirds) with small semicircular crest with smooth edge; transtilla process basally wide, sharply narrowing to apex, apical third of process very thin, curved, apex acute; juxta tiny, with pair of small oval lateral processes; saccus tiny; phallus about 4/5 of valve in length, phallus of the same thickness from base to middle of length, from middle smoothly narrowing to apex, vesica aperture in dorso-apical position, about 2/5 of phallus in length, vesica without cornuti.  
Female. Slightly bigger than male, length of fore wing 11−15 mm, antenna filiform, about ½ of fore wing in length, wing pattern analogous to that of male, ovipositor very long. Genitals not examined.  
 Diagnosis. The new species differs sharply from all the known Central Asian species of the genus Dyspessa in the poorly modified wing pattern. Additionally, an important character is the relatively long antenna in the males (longer than 1/2 of fore wing). There are also important distinguishing features in the male genital structure: the transtilla process sharply narrows to the apex, the apical third of the process is very thin, curved, the apex is acute.   
 Distribution. South-Western Kyrgyzstan (Ferganskyi Mt. Range) (Fig. 10).   
 Etymology. The new species is named after the famous Kyrgyz entomologist Dmitry Milko (Bishkek), an excellent expert on the Central Asian entomofauna.
