Habitus as in Fig.
Head wider than long, widest across eyes; punctation coarse and sparse; interstices glossy. Mandibles without distinct sexual dimorphism. Eyes distinctly convex. Antenna as in Fig.
Pronotum nearly oviform, strongly convex in cross-section; punctures somewhat sparser and shallower than those of head.
Elytra trapeziform; punctation coarse, defined and dense. Hind wings reduced. Metatarsomere I as long as combined length of metatarsomeres II and III.
Abdomen distinctly broader than elytra; punctation coarse; interstices with very shallow microsculpture; posterior margin of tergite VII without palisade fringe.

The type locality is situated in the Micang Shan to the north of Nanjiang, northern Sichuan. The specimens were sifted from leaf litter in a mixed deciduous forest at an altitude of 1,800 m.
The species is dedicated to Wang Xu, who collected some of the type specimens.
As can be inferred from the highly similar sexual characters, the new species is allied to the geographically close
