A study on the genus Compsidolon Reuter, 1899 from China (Hemiptera: Heteroptera: Miridae: Phylinae), with descriptions of three new species.

Compsidolon Reuter from China with eleven species is reviewed here. Three of them, C. ailaoshanensis, C. flavidum, and C. pilosum are described as new to science. C. eximium (Reuter) is recorded from China for the first time. Compsidolon punctulatum Qi and Nonnaizab, 1995 is treated as a junior synonym of Compsidolon nebulosum (Reuter, 1878). A key to Chinese species of Compsidolon Reuter is given. Photographs of dorsal habitus, scanning electron micrographs of metathoracic scent-gland, and illustrations of male genitalia are also provided. All type specimens are deposited in the Institute of Entomology, Nankai University, Tianjin, China.
