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.
