Taxonomy of genus Orophyllus Beier, 1954 (Orthoptera: Tettigoniidae: Pseudophyllinae).

Only one species, Orophyllus montanus occurring in southern China is placed in Orophyllus. In this study, we studied samples from Hainan, Guangdong, Guangxi, Guizhou, Sichuan and Zhejiang enabling us to provide new information on this genus. Gene tree was constructed by COI gene. The results showed that there were new taxa other than the type species, namely O. grandivalvatus sp. nov. (), O. nigrisartorius sp. nov. (), O. supeciliarilamellatus sp. nov. (), O. guttatus sp. nov. () All materials were deposited in Biological History Museum of East China Normal University (ECNU) and the Shanghai Entomological Museum, Chinese Academy of Sciences (SEM).
