Description. Male. Length of fore wing 17 mm. Fore wing grey with dense dark-grey reticulated pattern throughout all wing, poorly expressed dark spots in root area and discally, fringe grey, unicolorous. Hind wing white with dense dark-grey reticulated pattern, more expressed postdiscally and submarginally, fringe mottled dark-brown at veins (in thick bundles), light-brown between veins.

Male genitalia. Uncus robust, distally split to middle by deep notch, halves of uncus strongly widened; gnathos arms very short, thin; costal edge of valve slightly curved, with tapered finger-like process apically, abdominal edge strongly curved, outer edge semicircular; juxta large, scaphoid, with long sharp subulate abdominal process; saccus tapered, long, apically slightly sharpened; phallus shorter than valve, vesica without cornuti.

Female. Unknown.

Diagnosis. Externally, the species is mostly close to D. morosa ( Schaus, 1911) , D. ostrovskyi Naydenov, Yakovlev, Penco & Sinyaev sp. nov., D. pushkini Naydenov, Yakovlev, Penco & Sinyaev sp. nov. and D. rubtsovi Naydenov, Yakovlev, Penco & Sinyaev sp. nov. from which clearly differs by the tapered finger-like process apically on the costal edge of the valve.

Distribution. Venezuela.

Etymology. The new species is named after the Russian poet, writer, critic and publisher Nikolay Alexeyevich Nekrasov.
