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.
