A revisional study of the Chinese species of Amphiops Erichson (Coleoptera, Hydrophilidae, Chaetarthriini)

Abstract

A review of the genus Amphiops occurring in China is provided. A new species, Amphiops coelopunctatus sp. nov., is described from Hainan, China. Based on a study of the type material, Amphiops yunnanensis Pu, 1963, is proposed as a junior synonym of Amphiops mirabilis Sharp, 1890. Amphiops pedestris Sharp, 1890 and Amphiops annamita Régimbart, 1903 are confirmed as synonyms of Amphiops mater Sharp, 1873. Amphiops coomani d’Orchymont, 1926 is reported from China for the first time. Amphiops globus Erichson, 1843, previously reported from Macau, is found to be a misidentification. An identification key to Chinese species of the genus is provided.
