Type species: perornata Warren, New Guinea.
The facies of both wings is striking, consisting of pale straight
antemedial and postmedial bands that are edged with iridescent golden scales and
set in a rich buff ground. There is also a narrow band of iridescent gold along
the distal margins of both wings. The forewing fasciae are flexed sharply basad
subcostally. The male antennae are slightly serrate, strongly ciliated. The
abdomen in both sexes has the apodemes of the second tergite moderately
developed, though not nearly as long as in Carbia and allies.
The male genitalia have the uncus small, hooked, and the subscaphium is
sclerotised. The valves are long, narrow, the labides broad, meeting centrally
to give a bilobed or quadrilobed, finely setose structure. There is a prominent
furca. The aedeagus is short, broad, with the vesica generally scobinate, with a
rather convolute cornutus.
The female has a very broad ostium that opens directly with a rather
sheath-like bursa, sclerotised and fluted over the basal two-thirds and
extensively spined but more membranous in the distal part.
The genus consists of only two species with an unusually disjunct
distribution (New Guinea; Sundaland).
