Diagnosis. This species resembles D. bilobatus sp. nov. and D. antennatus in the size, antennae, the shape of male sternite VIII and the female spermatheca. This species can be distinguished from D. bilobatus sp. nov. by longer parameres and different inner structure of the male aedeagus. In comparison with D. antennatus, this species possesses a round elevation between eyes in males, while D. antennatus is lacking such elevation. Besides this, the inner structure of aedeagus is also different from D. antennatus.
Distribution. China (Hainan, Yunnan), Thailand, Myanmar.
