Clethrorasa
Hampson
Type
species: pilcheri Hampson.
This
is a small Oriental genus containing species with striking pale cream forewings
with a black discal mark and single and paired marks of the same colour round
the margin. The thorax is similarly marked. The hind-wings and abdomen are grey,
marginally or apically the cream colour of the forewings.
The
male abdomen has trifine hair pencils. The eighth sternite has short, weak
lateral rods. In the male genitalia the sacculus lacks a harpe but has (in one
species) a distal obtuse angle that overlaps a process extending obliquely from
the costa to end in a spine at the ventral margin at three quarters. This
process occurs in both species. The aedeagus vesica is tubular, bearing
numerous, evenly spaced, short, broad, thorn-like cornuti.
In
the female genitalia the ductus bursae is simple, short, evenly sclerotised,
overlapped by finely folded basal lobes from the bursa, which narrows before
expanding into the main part of its volume, an elongate, corrugate, lightly and
finely scobinate sock.
