( Figs 7–8 , 23 , 32 )

Caviria chrysoscela Collenette, 1934a: 114 .

Leucoma chrysoscela: Collenette, 1938: 220 ; Chao, 2003: 288; Wang et al., 2015: 583.

Stilpnotia chrysoscela: Chao, 1978: 55 .

Diagnosis. The species is very superficially simiar to L. ochripes , but can be distinguished from the latter by tarsi pale yellow, with white band terminally; pectionations of antennae dark-brown. The species is also similar to L. impressa ( Snellen, 1877) in male genitalia, but can be easily separated from the latter by the right valva longer than the left one, without bifurcation at cucullus.

Material examined. 1♂, Nanling National Nature Reserve, Ruyuan County, Shaoguan City , Guangdong, 11– 14. V.2018, leg. M. Wang. 1♀, Chebaling National Nature Reserve, Shixing County, Shaoguan City , Guangdong, 28–31. V.2019, leg. M.

Distribution. China (Zhejiang, Fujian, Jiangxi, Guangxi, Guangdong, Hainan), Vietnam.

Remarks. The female genitalia of this species are illustrated here for the first time. The anterior apophysis is almost as long as posterior apophysis, the ostium is relatively small, the ductus broad basally, narrow distally, and the bursa with a stripe-like signum.
