Material. Holotype, male, Vietnam, Central Highlands Region, Kon Tum Province, Dak Glei district , 1 km NW Dak Man village, N15°13ʹ24.4ʹʹ; 107°43ʹ50.6ʹʹ, H – 1080 m, 11−26.v.2017, leg. A. Korshunov (Zoological Institute, St. Petersburg, Russia), slide AN010 coll. RV Yakovlev.

Description. Male. Length of fore wing 22 mm. Antennae belt-like, not pectinate. Bundle of red scales on forehead. Fore wing light-grey with fine reticulated dark-grey pattern on all area of wing, discally pattern more dense. Fringe light-grey between veins, grey at veins. Hind wing dark-brown, without pattern.

Male genitalia. Uncus triangle, apically acute, basally wide; tegumen robust; gnathos arms thin, long; gnathos compact, strongly sclerotized; valve relatively long, lanceolate, distal third poorly sclerotized, costal margin (on border between sclerotized and membranous part) with process shaped as two strongly sclerotized lamellar lobes, valve apically semicircular; transtilla process thick, hook-like, apically sharp; juxta tiny with long thin lateral processes diverged at acute angle; saccus semicircular, robust; phallus long, thin, poorly curved throughout all length, vesica aperture about half of phallus in length, in dorso-apical position; vesica without cornuti.

Female unknown.

Diagnosis. The new species clearly differs from the known species of the genus in the very sharp apex of the uncus and in the process on the costal edge of the valve shaped as strongly sclerotized double plate.

Etymology. We name the new species in honor of the famous Russian botanist, president of the Russian Botanical Society Leonid V. Averyanov (St. Petersburg), a prominent specialist in the flora of Indochina.
