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

Five new species of the ant-like stone beetle genus Horaeomorphus Schaufuss (Scydmaeninae: Glandulariini) from China are described: H. hainanicus sp. n., H. biwenxuani sp. n., H. pengzhongi sp. n., H. hujiayaoi sp. n. and H. punctatus sp. n. The previously unknown male of H. 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.
