Frisilia sulcata Meyrick, 1910

( Figs 7 , 11 , 18 )

Frisilia sulcata Meyrick, 1910a: 437 . TL: India (Khasi Hills). TD: NHMUK.

Material examined. CHINA, Xizang: 3³, Shenhu, Jilong Town , Jilong County, 2772 m, 11.VII.2019, leg. MJ Qi & JQ Deng, slide No. YS 20008; 4³, Chongse Village , Jilong Town , Jilong County , 2640 m, 14.VII.2019, leg. MJ Qi & JQ Deng, slide No. YS 19469 .

Adult ( Figs 7 , 11 ). Wingspan 17.0‒18.0 mm.

Diagnosis. This species is similar to F. cornualis and F. neacantha Wu & Park, 1999 in the male genitalia. It can be distinguished by the cucullus with a ventrobasal process, and the aedeagus with two plate-shaped cornuti ( Fig. 18 ). In the latter two species, the cucullus lacks a ventrobasal process, and the cornuti are horn-shaped in F. cornualis ( Park 2008: 22, fig. 51) and absent in F. neacantha ( Wu & Park 1999: 4, fig. 10).

Distribution. China (Xizang), India, Nepal.

Remarks. This species is recorded for the first time in China.
