Chrysopera Hampson

Type species: combinans Walker, Sri Lanka.

The general appearance is similar to that in the
Avitta sequence of genera, except the male antennae are narrowly bipectinate (not much more than serrate). The basic facies is similar to that of Pantura rufifrons (see above), except the type species has a well defined paler patch distally on the forewing costa, and the hindwing apex is broadly yellow.

In the male abdomen, the eighth tergite is broad, with stronger sclerotisation in a weak W-shape. The sternite is trifid distally, with the central lobe better defined but shorter than the ones on each side. The genitalia appear superficially similar to those of Asta, Pantura and Heoeugorna, but lack a scaphium and have the tegumen distinctly shorter than the vinculum. The valves are more broadly attached to the rest of the capsule and have a basal hair-pencil; there is a small digitate process centrally. The juxta is a broad version of the inverted ‘V’ type, with the anellus set well within its apex. The uncus has a distinctly narrower apical spine.

The female genitalia have features somewhat intermediate between those of the previous two genera.

A New Caledonian species described in
Avitta by Holloway (1979) with facies much closer to Pantura rufifrons has male genitalia with all the features of Chrysopera and is therefore transferred to the genus as C. pectinata Holloway comb. n.

The larva of the type species is described below.
