Figs 1−2

Material. Holotype, male, Tajikistan, Darvaz Mts. , Khaburabot pass, 3100 m, 17.vii.2018, leg. I. Pljushtch (slide # AN038; Zoological Institute, Sankt-Petersburg, Russia).

Description. Male. Antenna twice shorter than fore wing, bipectinate, setae 2−2.5 longer than antenna stem in diameter (in medium third). Length of fore wing 9 mm. Fore wing grey with small lightochre spots in discal cell and on border between veins, fringe mottled (grey at veins, light coloured between veins). Hind wing grey, without pattern, fringe grey unicolorous.

Male genitalia. Uncus triangular, apically acute; gnathos arms of medium length; gnathos poorly structured; valve lanceolate with poorly sclerotized apical tip, costal margin of valve (on border between medium and distal third) semicircular process with uneven edge; transtilla process short, triangular, basally very thick, apically blunt; juxta saddle-like, basally wide, with small lateral processes; saccus small, semicircular; phallus 1/4 shorter than valve, thick, almost straight, narrowing to apex, vesica aperture in dorso-apical position, about 1/3 of phallus in length, vesica without cornuti.

Female unknown.

Diagnosis. The new species clearly differs from all the central Asian species of the genus in the very dark colour and the thick, almost straight phallus.

Distribution. Tajikistan, Darvaz Mts.

Etymology. The new species is named after a friend and teacher of the first author of this article, the well-known entomologist Dr. Igor Pljushtch, who, with his erudition and breadth of views, instilled in me the ability for self-development.

Notes. Dyspessa igoripljushtchi sp. nov. is the highest mountain species of the genus.
