Ganisa Walker
Type species: postica Walker.
The species are like small Eupterote but with a strong double postmedial only
present on the forewing. The male genitalia have the broadly bifid uncus not
fused with the tegumen as in Eupterote, and often with the indication of a
double central process. There is a broad, planar gnathus. The valve has a spur
at the apex of the sacculus. In the female the bursa and ductus are long,
slender, the former with a single thorn-like signum. The eighth segment is a
narrow, complete ring. The seventh sternite is reduced, membraneous as in
Eupterote.
The larva of G. plana is described below. Bell (MS) reared G. postica in S.
India. The larva is clothed with appressed dense short grey fur that hides the
surface completely. Paler hairs occur laterally and subspiracularly in dense
erect tufts on most body segments. In addition, long, fine hairs are scattered
over the body, being particularly dense at the anal extremity. The
intersegmental zone is black, seen in motion; the spiracles are whitish and
visible; there is a light
yellow dorsal line and the venter is black. The host-plants recorded were
Jasminum and Olea, both Oleaceae, the former being also the host-plant of
G. plana.
