Falana Moore
Type
species: sordida Moore,
India.
The
forewing shape and bipectinate male antennae are similar to those of the
previous genus, but the reniform is picked out paler as a transverse bar or
connected double dot. The postmedial is obscure in the type species but a
transverse double dark line in the new species. There are slight scale crests on
the male hind tibia in the type species.
In the
male abdomen, the eighth segment is modified with the sternite much broader and
shallower than the tergite, but both with a marked W-shaped anterior margin
(more extreme in the new species below). In the genitalia the scaphium is well
displaced up the uncus. The valves are simple, rather broad, with well developed
coremata. The saccus is shallow, broad, narrowly excavate centrally.
The
juxta is broad, platelike, but with some semblance of an inverted ‘V’ over
its ventral part. The aedeagus is straight, narrow, the vesica small with some
scobination.
The
female genitalia have the ostium associated with the eighth segment as in other
members of the tribe. It tapers into the long ductus bursae, which has a
scobinate sclerotised constriction at the distal end of the taper and just basal
to the origin of the ductus seminalis. Most of the length of the ductus is
distal to this and has an abrupt narrowing at the midpoint. The bursa is ovate,
with a narrow, longitudinal band of scobination at one third.
The
genus consists of the two species discussed below.
