Diagnosis. See
the generic description. The triangular shape of the forewing apical black and
red zone is diagnostic.
Geographical
range. Sundaland.
Habitat preference. Only
one specimen has been taken in recent surveys, day-flying at 150m during the
Mulu survey. Older material seen is from Kuching, Pontianak and Sandakan.
Biology. The
larvae were described by Piepers & Snellen (1904). They are bright ochreous
in ground colour, covered densely with white hairs. Over all except the head and
anal portion, the body has a greenish tinge, with T3 and A7 being black dorsally
and bearing several small, spiny verrucae. From T2 backwards, each segment has a
transverse line of yellowish white. The larvae were stated to be found on the
leaves of Mangifera (Anacardiaceae), but with no indication of what they
actually fed on.
