specks: nocturnus Hampson.
genus contains one large species with facies as described below. The abdomen of
the male is almost twice as long as the hindwings. A second species, C. socia
de Joannis from Tonkin, has not been examined.
male abdomen has a number of striking features. The basal sternite is long,
narrow, with no trifine hair pencil, as illustrated in Fig. 10. The eighth
sternite and the eighth tergite are both divided into two wing-like processes,
those of the tergite triangular; those of the sternite consist of two sclerites
with, distally between them as they splay apart, a more membranous zone that
bears a mass of long, fine hairs. The sternite has prominent, long lateral rods.
In the genitalia themselves the uncus is also completely divided, the tegumen
has finely hairy triangular processes on each side, and the valve is lightly
sclerotised, slightly S-shaped, without a corona. The aedeagus vesica is
elongate ovoid, finely scobinate.
the female genitalia the apodemes and ovipositor lobes are slender, the eighth
segment a simple sclerotised ring, and the ductus long, unsclerotised. The bursa
is set asymmetrically on the ductus like the foot of a large scobinate sock.
