Geographic range

Mainland China (Guangdong, Guangxi, Hainan, Hong Kong, Tibet, Yunnan), Vietnam.

New record for Guangdong and Hainan.

Ecology

Collected in primary and secondary forest, at elevations from 50 to 1190 m.

Comments

This species has been recorded from west to east: Tibet and Yunnan Province of mainland China, northern region in Vietnam, Guangxi Province and Hong Kong. The new records in Guangdong and Hainan presented here fill in the previous gap between Hong Kong and its remaining native range. Its presence in Laos seems also likely.
