The Leptusa fauna of China

Including ten newly described species and a new synonymy, the Leptusa fauna of China, Taiwan, and Hong Kong now includes 73 species and three subspecies in twelve subgenera, with three species not assigned to any of the available subgenera. In view of the number of new species and of the fact that some species have not yet been revised, it appears likely that additional species and synonymies remain to be discovered in the future.

The distributions of two of the newly described species are somewhat doubtful. One of them, L. auriculata , was collected in several localities in Diangcang Shan and one in Emei Shan, and the other, L. emeiana , was found in several localities in Emei Shan and one in Diancang Shan. The respective specimens were collected by the same entomologist in mountain ranges separated by a considerable distance in the same year, suggesting that these records may be partly based on mislabeled material.
