Differential diagnosis. For distinguishing characters from D. pulcher see below.

Bionomy. Found in primary forests, as well as park and Damar garden. It was twice collected on tree trunks, one of Lansium domesticum (Meliaceae) . Mating was observed in August (Sabah), October (West Sumatra), and November ( Sarawak). Distant (1903) wrote: ‘This species is not uncommon in August and September on the trunks of trees in the jungle on Bukit Besar (2,500 ft). The very young larvae have something of resemblance to small specimens of the ant Oecophylla smaragdina , while the adults might be mistaken at a casual glance for newly-hatched larvae of the mantis Hymenopus bicornis , though they are not generally found in the same situations.’

Distribution. Myanmar ( Distant 1904); Thailand: Pattani ( Distant 1903), Satun ( Stehlík & Jindra 2003); Malaysia: Melaka ( Stål 1870), Natoena Besar [= Great Natoena Island] ( Blöte 1931), Pahang (new record), Sabah (new record), Selangor (new record), Sarawak (new record); Indonesia: Bali (new record), Java ( Stål 1863, Walker 1873, Breddin 1905a, Blöte 1931), Sulawesi (new record), Sumatra ( Breddin 1901a, Blöte 1931, Schmidt 1932, Schouteden 1933), Timor ( Blöte 1931). Fabricius (1803) described this species from China, but it has never been found in China afterwards, so the type locality seems to be given in error (see Kerzhner 2001); I agree with this statement. Distant (1904) reported this species also from Borneo [= Kalimantan], which is confirmed here (records from Sarawak and Sabah). On the other hand, records from Philippines (e.g., Walker 1873, Distant 1904, Schmidt 1932) clearly concerns other species, especially D. pulcher .
