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.
