Measurements in Table 8.

Distribution. China (Guizhou).

Notes. The left foreleg of the holotypic male is a regenerated leg and measurement and description are only given to the right foreleg. The egg description, illustrations and measurements are insufficiently provided because the extracted eggs removed from the abdomen of the paratypic female are in an immature stage.

Etymology. This species is named in honour of Peng Zhong [specialist of Staphylinidae (Coleoptera) , Shanghai, China] who helped me in many ways during the collecting trips in Guangxi and Guizhou, China.
