Contributions to the knowledge of the genus Horaeomorphus Schaufuss (Coleoptera Staphylinidae Scydmaeninae) in mainland China

摘要

Five new species of the ant-like stone beetle genus Horaeomorphus Schaufuss (Scydmaeninae: Glandulariini) from China are described: Horaeomorphus hainanicus >sp. n., Horaeomorphus biwenxuani >sp. n., Horaeomorphus pengzhongi >sp. n., Horaeomorphus hujiayaoi >sp. n. and Horaeomorphus punctatus >sp. n. The previously unknown male of Horaeomorphus chinensis Franz, 1985 is now discovered, and its aedeagus and metatrochanter are illustrated. The latter species is newly recorded from Zhejiang. Three females from Guangxi are also recorded, but their identity remains unconfirmed until associated males become available. A key to Horaeomorphus of mainland China is included.
