Diagnosis. The new species is most similar to D. ulula ( Fig. 4D ), from which it differs by:

- the dark wings ( D. ulula is much paler, the basic background is yellowish, the pale spots are much more expressed);

- the expressed stepped bending on the costal edge of the valve (in D. tristis ( Fig. 5A ) and D. saldaitisi ( Fig. 5B ) the finely serrated surface on the costal edge of the valve in medium third; in D. ulula ( Fig. 5C ), the costal edge of valve is smoothly rounded; in D. saissanica ( Fig. 5D ) the proximal end of the process on the costal edge of the valve is sharp;

- the phallus strongly bent in the medium third (in D. ulula , the phallus is less curved). The new species also differs from D. saissanica , D. saldaitisi D. tristis , and D. ulula ( Figs 4C, 4E, 4F ,) by the well-expressed dark color of the wings. Genetically, the new species differs from most closely related D. ulula by at least 36 fixed nucleotide substitutions (p-distance is 5.5%) within the studied 658bp fragment of the mitochondrial COI gene.

COI barcode sequence of the holotype, 658 base pairs.

Description. Male. ( Fig. 4A ) Length of forewing 10 mm. Antenna bipectinate, equal to half of the forewing length, antenna crest 1.5 times of antenna rod diameter. Thorax and abdomen are densely covered with pale grey scales. Forewing grey with a poorly developed pale pattern of pale cream spots along the costal edge in the discal cell, and two spots in the cubital area (one at wing base, second in the discal area). Fringe mottled, dark at veins, pale between veins. Hindwing ground colour and hindwing fringe grey, unicolorous.

Female ( Fig. 4B ). Length of forewing 9‾ 11 mm. Antenna bipectinate, equal to half of the forewing length, an-tenna crest 0.5 times of antenna rod diameter. Thorax and abdomen are densely covered with pale grey scales. Wing pattern resembles that of males.

Female genitalia ( Fig. 5F ). Ovipositor long, papillae analis semicircular, anterior apophyses three times shorter than posterior apophyses, ostium aperture slit-shaped, narrow.

Male genitalia ( Fig. 5E ). Uncus triangle, apically blunt; gnathos arms short, thick; gnathos small, poorly sclerotized; valve basally sclerotized, caudal end membranous, lanceolately narrowing, stepped bending on the costal edge of the valve (in medium third); transtilla process short, basally very wide, apically narrowing, apex semicircular; juxta tiny, with a pair of short rod-shaped lateral processes; saccus semicircular, robust; phallus equal to 3/4 of valve length, thin, apically narrowing, strongly bent in the medium third, vesica aperture in dorso-apical position, equal to 2/3 of phallus length, vesica without cornuti.

Distribution. Kazakhstan (Eastern Kazakhstan Province), Russia (Altai Krai Province).

Etymology. Ulgen’—demiurge, the supreme deity in shamanism of Altaians, Khakas, and Shors.
