Barsine kanchenjunga Volynkin & Černý , sp. nov.

( Figs 4 , 33 )

Type material. Holotype ( Figs 4 , 33 ): ♁, [NE India] “ Sikkim, Mt. Kanchenjunga Himal , 27°30’N, 88°20’E, 2600 m, 9–10.VIII.1995, leg, Afonin & Sinajev”, slide MWM 33583 Volynkin (Coll. MWM / ZSM).

Diagnosis. Forewing length is 13.5 mm in males. Barsine kanchenjunga differs externally from the related B. inflexa and B. victoria by its larger size, broader forewing with more elongated apex, postmedial line being angled opposite the cell (in B. inflexa and B. victoria that is W-like curved opposite the cell), less enlarged connection of antemedial and medial lines, and pale ochreous hindwing (whereas in B. inflexa and B. victoria hindwings have pinkish suffusion). The male genitalia of B. kanchenjunga resemble those of B. victoria , but differ by the medial part of uncus being straight (that is evenly curved in B. victoria ), longer and broader tegumen, less curved costa, longer medial costal process, distal costal process situated more dorsally, smaller distal membranous lobe of valva, narrower and longer sacculus, longer and much narrower distal saccular process, less curved aedeagus, larger subbasal diverticulum of vesica bearing broader cluster of smaller cornuti surrounded by granulation (in B. victoria the subbasal diverticulum bears a compact cluster of more robust cornuti), smaller cornuti on the medial diverticulum, the absence of a ventral medial diverticulum, the presence of the medial area of granulation, and the larger distal diverticulum bearing longer cluster of more robust cornuti basally and medially.

The female is unknown.

Distribution. The species is known only from its type locality, Mount Kanchenjunga in the Indian State of Sikkim.

Etymology. The species name refers to its type locality, Mount Kanchenjunga.
