Tochara Moore Gen. rev.
Type
species: obliqua Moore
= creberrima
Walker.
This
genus resembles Hypospila in general facies as discussed under that genus,
differing in features such as the long, bipectinate male antennae, a longer
third segment of the labial palps and possession of a distinctive dark spot
submarginally, anteriorly on the hindwing. Both genera have a prominent peak of
scales at the front of the head above the naked area of the clypeofrons.
The male
eighth segment is of the framed corematous type, with a well-developed, single
corema centrally in the sternite. The genitalia have the uncus simple, not
strikingly modified. The valves are broadly based, tongue-like, with a massive
process arising near the base of the costa, its base extending across towards
the apex of the sacculus. The juxta is a narrow plate, or almost vestigial, but
there is a prominent transtilla associated with the anellus. This transtilla is
more developed than in Hypospila.
The aedeagus has small apical spine. The vesica is small, not convolute, without
conspicuous ornamentation.
In the
female, as in Hypospila, there is a small U-shaped sclerite ventrally on
eighth segment, posterior to the ostium which is situated at the posterior of
the seventh segment. The seventh segment has the sternite slightly reduced and
trapezoidal, with the posterior corners of the tergite extended and wrapped
round. The ductus is strongly sclerotised, moderately broad, tapering slightly
to a constriction at the juction with the small, slightly 8-shaped corpus bursae.
The ductus seminalis arises from near the central constriction of the corpus
bursae.
Tochara
is
probably the sister-genus to Hypospila and
contains the two species described below.
