Type species: discolor Warren,
The very dark dull green wings, the bifalcate margin of the forewings, and the
configuration of the pale patches on the wings are distinctive. The pattern is
repeated on the underside. The male antennae are moderately bipectinate to about
three-quarters. The hindwing margin is angled.
In the male abdomen setal patches on the third sternite are lacking. The
eighth segment is sclerotised, modified, the sternite squarish, narrower than
the tergite, both distally shallowly excavate, the former also scobinate. The
genitalia have the uncus strap-like, apically lobed or bifid, flanked by two
strong socii. The valves are rather rectangular, the interior face ornamented
with irregular patches of small, peg-like setae. There are small coremata. The
aedeagus is narrow, rather needle-like.
The female (T. energes Prout) has ovipositor lobes pigmented and somewhat
rugose, tending towards the condition of the modified state, but in shape they
are rounded rather than obliquely bevelled. The sterigma is strongly sclerotised,
convolute, pouched, the bursa weak, spindle-shaped, set on a narrow ductus.
There is a bicornute signum.
Apart from the type species, the genus includes T. enervata Inoue
(Japan) and the Sundanian species described below.
