Egogepa crassata Wang and Li , sp. n.

(Figs. 3, 6)

Type material: Holotype: ɗ, CHINA: Mêdog County (29º13' N 95º18' E), Tibet Zangzu Autonomous Region, 1100 m, 14.viii.2003 (Xinpu Wang and Huaijun Xue), genitalia slide no. WXP03266.

Diagnosis. The new species is similar to Egogepa zosta by having a specialized “scent organ” in the hindwing and lacking the coecum penis. It can be separated from the latter by the complete and distinct medial fascia, the long uncus, the slender socius, and the lateral process of the gnathos.

Description. Adult (Fig. 3): Wingspan 13.0 mm. Labial palpus short, length about 1.0 times diameter of compound eye; frons, antenna, and tegula yellowish; thorax pale brown. Forewing expanded distally, lacking costal fold; apex short and blunt; termen obliquely straight. Ground color of forewing whitish yellow, with scattered dark brown scales; pattern elements dark brown: basal blotch and subapical blotch indistinct; medial fascia extending from middle of costa to dorsum, broad posteriorly; cilia pale yellowish. Hindwing and cilia pale gray, with a large cluster of broad scales between anal and cubital veins (= scent organ?). Legs whitish yellow, with some brown scales.

Male genitalia (Fig. 6): Tegumen broad and short, lateral sclerite large, boot-shaped. Uncus long, thick, slightly expanded from middle, pointed apically, densely covered by a group of sclerotized sockets of bristles or scales; socius slender; gnathos with strong lateral processes. Transtilla bandlike, broadened laterally. Valva broad, expanded distally; costa long, well developed; sacculus strongly sclerotized, narrow, long. Aedeagus short, narrow, weakly sclerotized, slightly narrowed beyond middle; coecum penis lacking, caulis small; no cornutus in vesica.

Female: Unknown.

Distribution. China (Tibet).

Etymology. The specific name is derived from the Latin word crassatus (= crassus), referring to the long uncus.
