Type species (by original designation) Langsdorfia bellaria Dognin, 1911 .

Description. Adults ( Figs 1−4 ) of relatively big size, wingspan 40−60 mm. Antenna bipectinate, crest processes two-three times longer than antenna rod diameter. Antenna about ½ of fore wing in length. Fore wing elongated, apically sharp. Contrast undulated pattern of dark spots with curly contours at root, postdiscally and submarginally. Hind wing short, apically sharp, semi-transparent, pattern poorly expressed. Fringe on all wings mottled (dark at veins, light between veins).

Male genitalia ( Figs 5−7 ). Uncus long, clavately extended in distal third, apically sharp; tegumen robust; gnathos arms reduced; valve robust, apically semicircular or lanceolate, costal edge basally with large long harpe with smooth edges, gradually narrowing from base to apex, valves on preparation laid out at an angle of 180º relative to each other; juxta scaphoid, with pair of relatively long lateral processes; saccus small, tapered, phallus shorter than valve, thin, slightly curved, vesica aperture in dorso-apical position, about ¼ of phallus in length, vesica without cornuti.

Female. Unknown.

Diagnosis. The new genus clearly differs from all the known representatives of Hypoptinae externally: in general, the specimens are relatively bigger, with semi-transparent hind wings. In the male genitalia, the apomorphic feature is the completely reduced gnathos.

Composition. The new genus includes three species: Laberlia bellaria ( Dognin, 1911) , L. illapai Yakovlev, Naydenov, Penco sp. nov., and L. apusorum Yakovlev, Naydenov, Penco sp. nov.

Distribution ( Fig. 8 ). Andean part of Colombia, Ecuador, and Peru.

Biology. The moths were attracted to light.

Etymology. “ Laberlia ” is an anagram of the species name “bellaria ”.
