Tasta reflexoides sp. n.

Tasta reflexoides

, 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.
