Abstract
Seven species of the subgenus Duolandrevus (Eulandrevus) Kirby, 1906 have been recorded from China prior to this study. Their morphology is similar, and genitalia can be used for distinguishing different species in earlier research. We describe one new species, D. (E.) obsidianus He sp. nov. from Guangxi. The new species is similar to related species in gross morphology, but showed differences in genitalia with epiphallic lateral lobes bifurcated apically in right angle. The songs and COI genes are first compared in this study, and the results support the validity of the new species. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
