Abstract

The genus Microichthyurus Pic, 1919, from China and its adjacent areas is reviewed. M. robusticeps Pic, 1923 (Laos and Vietnam), is redescribed. Nine new species are described from southern China, including M. falcatussp. nov., M. quadratussp. nov., M. crassicornissp. nov., M. nigersp. nov., M. tertiussp. nov., M. guangxiensissp. nov., M. flavipennissp. nov., M. bimaculatussp. nov., and M. strictipennissp. nov. These species are illustrated with habitus and genital segments of both sexes, as well as aedeagi. Four species groups are defined, and each is provided with a key for species identification and a distribution map.
