Material examined. Holotype ♂: Peru, prov. Huánuco, Yuyapichis, ACP Panguana , 9°36′′ S / 74°56′′ W, September 2013, 220 m, leg. H. Thöny (GenPr- Heterocera MWM 36.986 ) ( MWM) ; Paratype 1 ♂: Peru, prov. Huánuco, Yuyapichis, ACP Panguana , 9°36′′ S / 74°56′′ W, September 2013, 220 m, leg. H. Thöny ( MWM) .

Description. Male. Length of fore wing 20 mm. Fore wing light-brown with S-shaped wide light-brown stripe from wing root to anal angle and series of brown spots of various shape, fringe brown, unicolorous. Hind wing dark-grey, almost without pattern, fringe brown unicolorous.

Male genitalia. Uncus relatively short, deeply bifurcated, each half of uncus with small tapered prong, directed medially; gnathos arms very short, thin, narrowing from base to apex; valve long, abdominal edge slightly curved, costal edge with deep cut on border between basal and medium thirds, long strongly curved spiky process in distal third, valve apically semicircular with long finger-like process; juxta very large with sharp subulate abdominal process; saccus tapered, apically blunt; phallus short, vesica without cornuti.

Female. Unknown.

Diagnosis. The new species clearly differs from all the known species in the shape of the valve: the slightly curved abdominal edge, the deep cut on the border between the basal and medium thirds of the costal edge, the long strongly curved spiky process in the distal third, the semicircular apex of the valve with a long finger-like process. The species is mostly close to D. bulgakovi Naydenov, Yakovlev, Penco & Sinyaev sp. nov. from which it differs by the long process on the apex of the valve.

Distribution. Peru (prov. Huánuco).

Etymology. The new species is named after the Russian playwright and short-story writer Anton Pavlovich Chekhov.
