Diagnosis and taxonomic note. This species is sexually dimorphic as in flabrifera, the females being much paler and yellower than the males and with more elongate, ovate forewings, but there is a black marginal zone to the forewing underside that is more pronounced than in chilomorpha. Males also have the antennae slightly swollen over several flagellomeres each side of and including the tenth. The synonymy recognises this dimorphism, nodicornis being based on the male and rotundipennis on the female.

Geographical range. Borneo, Peninsular Malaysia, Burma, N.E. Himalaya.

Habitat preference. One female was taken in hill dipterocarp forest at 150m on G. Mulu, a male and female at 600m in forest at Poring on G. Kinabalu, and a male at 300m in the Ulu Temburong forest of Brunei.
