Tortriciforma Hampson
Type
species: viridipuncta Hampson, Sikkim.
The forewings and their markings are somewhat tortricid-like, the costa is sinuous, bowed basally and
concave distally, and the distal margin irregularly bifalcate anterior to a
rounded tornus. There is some sexual dimorphism, males tending to be darker in
some species, and some have strong tufts of scales dorsally over the base of the
abdomen at each side, and plate-like structures from the thorax over the tymbals
ventrally.
In
the male abdomen, the tymbal organs have distinctive ovate structures on each
side of the central cleft, and there are a few carinae as in Parasinna
Kobes (see below). The apodemes of the eighth tergite are long, splayed from a
central notch. The genitalia have a short uncus set on a wide tegumen that is
swollen on each side centrally. The valves are deeply based and broader
distally. There is a hair-pencil centrally on the sacculus rather than basally.
The aedeagus vesica has several diverticula, some of which have clusters of
slender cornuti apically, as in Tympanistes.
In
the female genitalia, the bursa is convolute, rather elongate, with spining
throughout or in patches.
The type species is the only member of the genus to occur outside Sundaland; see
also Kobes (1997).
