Cochylis discerta Razowski, 1970: 431. TL: Mongolia (Cantral [Tov] Province, 11 km S Zosijn Davaa Pass).

Material examined.

CHINA: Shanxi Province: 1 ♀, Xiyao Village, Ningwu County (39°00'N, 112°18'E), 1475 m, 21.vii.2011, leg. Shulian Hao and Jiayu Liu. Inner Mongolia: Mt. Helan, Azuoqi (38°48'N, 105°52'E), 2200 m, 10.viii.2011, leg. Lixia Li and Yinghui Mou. Gansu Province: 2 ♂♂, 2 ♀♀, Sunan Autonomous County (38°50'N, 99°36'E), 2251 m, 16.viii.2007, leg. Feng Yang and Hanguang Gao.

Description.

Adult ( Fig. 2 ) with wingspan 10.0-14.5 mm.

Female genitalia ( Fig. 13 ). Papilla analis gradually narrowed posteriorly, about 1/3 length of apophysis posterioris. Apophysis anterioris about 3/5 length of apophysis posterioris. Sterigma a heavily sclerotized ring. Antrum heavily sclerotized, about 1/4 length of corpus bursae, anterior 1/3 curved in hook shape; ductus bursae extremely short, membranous. Corpus bursae elongate oval, membranous, densely suffused with tiny spines; ductus seminalis arising from posterior part of corpus bursae.

Diagnosis.

This species can be distinguished from its congeners by the broad transtilla and the absence of a median process in the male genitalia ( Fig. 7 ), and the ring-shaped sterigma and heavily sclerotized antrum in the female genitalia. Cochylis discerta Razowski, 1970 is very similar to Cochylis psychrasema (Meyrick, 1937), but Cochylis discerta can be distinguished by the ventral margin of the valva without a distal process in the male genitalia and the ductus bursae about 1/3 length of the corpus bursae in the female genitalia. In Cochylis psychrasema , the ventral margin of the valva bears a long spine-shaped process in the male genitalia and the ductus bursae is about 1/7 length of the corpus bursae in the female genitalia.

Distribution.

China (Gansu, Inner Mongolia, Shanxi), Mongolia.

Note.

The female is described here for the first time.
