Keywords: Hydrophilidae, new species, China, Oriental, Palaearctic


Representatives of the subgenus Helochares (s. str.) Mulsant, 1844 of China are revised. One new species, H. (s. str.) songi sp. nov., is described from Guangxi, China. All species known from China are redescribed. A diagnosis and a differential diagnosis are provided for each species. Helochares fuliginosus d’Orchymont, 1932 is recorded for the first time from China and Cambodia. Additional distribution records of H. atropiceus Régimbart, 1903 and H. pallens (MacLeay, 1825) are provided from China. The habitus and aedeagus of all species are illustrated, and a key for the identification of Chinese species of the subgenus is provided.
