Thoracolophotos Bethune-Baker
Type
species: ekeikei Bethune-Baker
New Guinea.
The
three included species are robust with fasciculate male antennae and rather
narrow triangular grey forewings crossed by a series of rather rippled fasciae,
with an oblique central boundary beyond which the ground becomes darker before
gradually fading away to the apex, as described in more detail below.
In the
male abdomen the eighth segment is only weakly modified, the tergite being
excavate at the centre of its anterior margin between two short, broad, angular
apodemes. In the genitalia the uncus is short, shaped like a bird’s head. The
valves are tongue-like, tapering, slightly upcurved, with a slight corona at the
apex.
In the
female genitalia (albilimitata Hampson), the ovipositor lobes are
relatively short, robust, with ornamentation somewhat as in the Episparis
Walker
group of genera (p. 293). The eighth segment is also short, almost a complete
ring, with the ostium at the anterior of the narrower ventral part. The ductus
is very short. The corpus bursae is small, barely extending beyond the anterior
of the unmodified seventh segment. It is elongate, pyriform, with an appendix
bursae about half its size arising basally from it.
In
addition to the type species and that described below, the genus also includes T.
javanicus Roepke
from Java, with facies very similar to that of the Bornean species.
