Diagnosis. This species is externally similar to D. lombokensis sp. nov., D. bogorensis sp. nov. and D. punctipennis . This species has shorter antennae, and first segments of protarsi strongly dilated, distinguishing it from D. punctipennis . Compared to D. lombokensis sp. nov. and D. bogorensis sp. nov., this species only has a shallow emargination on posterior margin of male sternite VIII, and the aedeagus of this species has parameres distinctly longer.

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