Phorica Walker
Type
species: phasipennis Walker.
This
genus has a general resemblance in the irregularity and texture of its facies to
Batracharta,
but the forewing is narrower and more normal in shape. The darker markings on
the forewing are more distal, with a white spot as described below. The hindwing
has only a weak discal spot, seen only on the underside. The male antennae are
more generally ciliate and the legs do not have conspicuous tufts. The labials
palps are shorter than in Batracharta but similarly proportioned.
In the
male abdomen the eighth segment is much as in Batracharta except
the apodemes of the tergite are shorter and more widely separated, and the
sternite is shorter and tapers more distally. The genitalia have the tegumen and
vinculum much less modified and approximately of equal length. The valves are of
similar breadth and shape to those of Batracharta but
have a small interior lobe towards the apex. The aedeagus and vesica are also
similar, but the latter has two short cornuti.
The
female genitalia have the ostium situated as in Batracharta,
but the ductus and corpus bursae are larger and more elongate, the former
densely scobinate and the latter, joined asymmetrically with the ductus,
distinctly pyriform, with slightly scobinate corrugations subbasally and with a
small, weakly defined, scobinate signum subapically.
The
genus consists of the type species and a closely related one in Sulawesi (slide
18684). The latter has the hindwing underside distinctly paler than that of the
forewing (more uniform in phasipennis).
The lobe of the valve is more basad, and there are slight differences in the
opening of the aedeagus and in the cornuti of its vesica.
