Female. Unknown.

Etymology. The specific epithet is derived from the Latin word palmatus (palm-shaped), indicating the character of right surstylus.

Specimens examined. Holotype, ♂, Guangxi, Wuming, Mt. Daming (800 m), 10-Aug-2011, Jianfeng Wang . Paratypes, 1♂, Guangxi, Wuming, Liangjiang (460 m), 11-Aug-2011, Jianfeng Wang ; 1♂, Guangxi, Mt. Maoer (1800 m), 14-May-2004, Guangchun Liu .

Distribution. China (Guangxi).

Remarks. With the characters of the palmate right surstylus and lacking inner teeth of each surstylus the new species can be distinguished from all other described species of the genus. In the keys of Disney (1990) and Michailovskaya (2000) the species will not run out to any species.
