Oxoia smaragdiplena


Diagnosis.
This species has the narrowest wings of all the green Bornean notodontids. The central submarginal black streak on the forewing is the most distinctive feature.

Taxonomic notes. Kiriakoff (1968) included one other species in Oxoia, irrorativiridis Bethune-Baker from New Guinea. Consideration of similarities of wing pattern and genitalia characters indicates two further species should be included as follows: O. [Somera] triangularis Gaede comb. n. (Schintlmeister, in preparation), from Buru; O. [Panteleclita] viridipicta Kiriakoff (1974: 419) comb. n., from Sumatra. It follows from the second change that Panteleclita Kiriakoff becomes a junior synonym of Oxoia Kiriakoff, syn. n. Both these transferred species have a subapical process from the valve costa, a long spine in triangularis and a broad flap in viridipicta.

Geographical range. Peninsular Malaysia, Sumatra, Borneo, Philippines.

Habitat preference. The species is found infrequently in various types of lowland rain forest but also more rarely at altitudes up to 2000 m.
