Material examined. THAILAND: 3 males, 1 female, Thailand, Ban Sai Yok, 9.III.82, G. de Rougemont (GROG, JJRC) ; 2 females, Thailand, Khao Yai N.P., Haew Narok Falls, 19.XI.2004, leg. W. Rossi (VAHG, JJRC) ; 1 female, Ko Chang NP, 10.12.90, leg. Forster (NHMW) .

Diagnosis. This species is externally similar to D. crispus sp. nov., but can be distinguished by the shape of male sternite VIII, which is only emarginate in the middle of posterior margin. Compared to D. antennatus, this species also has a shallowly emarginate basal transverse carina in the male sternite VIII, but the medial emargination of male sternite VIII in this species is distinctly deeper. Besides, the antennae of this species distinctly elongate. These characters can separate it from D. antennatus .

Distribution. Malaysia (Selangor), Thailand. The published records from other countries (Seychelles, Mauritius, Réunion, Rodriguez, Andaman Is., India) have to be verified.
