monoleuca was recorded by Chey (1994) singly in secondary forest near Brumas in the lowlands of Sabah. There is also further material in FRC Sepilok. from disturbed hill forest with cultivation at Apin‐Apin (700m) at Ulu Bundu near Tambunan. The forewings are very dark brown, grading a more steely black towards the apex. There is irregular, fine, blackish, dentate fasciation that is highlighted whitish, together with the reniform and orbicular, over the costal third; the postmedial flexes strongly basad from adjacent to the reniform towards the costa. There is a conspicuous white spot subapically on the costa.

Bell (MS) and Gardner (1946) described the biology, and the following account is drawn mostly from the former. The larva is cylindrical, tapering slightly at each end. A8 has a pair of acute, medium‐sized, conical tubercles dorsally. The prolegs are yellowish, the setae on black dots, those on A3 and A4 slightly smaller than the rest. The head is orange, the setae based on moderate to large black spots. The body surface is dull, the segments well defined, with primary setae only. The spiracles are black, as is most of the body, though there is thick marbling of grey in transverse lines. There is a longitudinal white line dorsally. Further supra- and subspiracular whitish lines enclose an orange band. Another variant was dark green, almost blackish in places, marbled with pinkish yellowish white.

The host plant recorded was Cordia.
