Dendrophleps cretacea sp. n.  

Dendrophleps cretacea (paratype)

24-26mm. This is a larger species than semihyalina (20mm), but with generally similar facies. In both wings M2 and M3 have a much shorter stalk (1mm or less) than in semihyalina, where the common stalk is about 2mm long. The veins are darkened distally in the Bornean semihyalina specimen but not so in cretacea or typical N.E. Himalayan semihyalina. The antennae are blackish as in semihyalina but are relatively slightly larger. The forelegs are orange, ringed narrowly with white at the distal end of each tarsal segment as in semihyalina. In the male genitalia, differences are slight, the apex of the right valve being slightly extended and upcurved. In the abdomen, the tergites are more darkly sclerotised than in semihyalina. Females are not known but might be expected to resemble large Leucoma.
