12-13mm. The species resembles T. reflexa Swinhoe (N.E.
Himalaya,
Sumatra) in general facies, lacking the discal mark of the previous species and
having the ocellus almost round, but the forewing postmedial is less sinuous
than in reflexa. The male genitalia show distinct differences from those
of reflexa and chalybeata, though sharing posession of a central
cornutus to the aedeagus vesica. This cornutus is accompanied by a pair of very
slender ones. The valve is apically rounded, basally slender, with a shallow arc
of six to seven digitate processes near the ventral margin extending from the
centre to three quarters.
