Diagnosis. Regarding to the similar shape of male sternite VIII, similar structure of the aedeagus and the spermatheca, this species is related to D. bisegmentatus and D. bilobatus sp. nov. In this species, the pronotum is more elongate and the aedeagus possesses longer parameres, which distinguished it from D. bilobatus sp. nov.. Compared to D. bisegmentatus , this species is without an elevation between eyes in males, and the inner structure of the aedeagus is different.

Distribution. Myanmar, Thailand, Malaysia. Published records from other regions of Indonesia (Sumatra, Java, Kalimantan [Borneo]), China (Taiwan) and Nepal have to be checked.
