Staphylinidae is one of the largest family in Coleoptera. They occupy a wide variety of habitats and have a wide range of food-habits. They are essentially carnivorous (insect feeder), but some groups have become evolved as mycophagous, coprophagous, carpophagous, pollinophagous and so on. Some species have adapted to a parasitism of mammals. Their prosperity is inevitably causing direct interaction between them and mankind.Oxytelus is one of genera of the subfamily Oxytelinae in the family Staphylinidae. It was established by Gravenhorst in1802, and designated Staphylinus piceus Linnéas the type species for the genus. Up to the present 198 species of the genus have been known from the world. They distributed cosmopolitan. There are 12 species known in China, of which 5 in the Mainland, 4 in Taiwan, 3 both in the Mainland and Taiwan.In China, however, taxonomic study on this genus is relatively behind and only some of scholars separately studied on this field. Up to the present, systematic works concerning Chinese Oxytelus has not been made. Nearly 90% of the Chinese known species were described by foreign scholars and the type specimens were deposited in foreign countries. For these reasons, it became difficulty for us to study Chinese Oxytelus fauna.This study was based on the examinations of over 800 specimens, which were collected from a lot of places in China such as Zhejiang, Guizhou, Shaanxi, and so on. The results of my research is summarized as follows:This paper was the first systematic study of the genus Oxytelus of China.In the present paper, 22 Chinese species of the genus were recognized, of which 12 species were described as new to science.All the species were described in detail, and their sexual characters were illustrated. The color photos for every species were also provided. The history review, collecting techniques, and major diagnostic characters of the genus were discussed.The key to the species of the genus was presented.A catalog of the genus Oxytelus of world was given.A database of all the known species of the genus Oxytelus in the world was built.
