11-12mm, 12-14mm. The ground colour is straw, the forewings suffused with darker brown and having a diffuse, oblique to sinuous, dark, narrow medial fascia. This fascia is obscured anteriorly in the male by a shallow, arcuate flap of scales extending back from the costa. This feature may be homologous with that in T. nigricauda but is more prominent, and the more basal tuft of nigricauda and allies is lacking. The male forewing venation is compressed in the region of the narrow cell and distal branches there from, with CuA2 strongly flexed at the base as in nigricauda and allies. The female has more normal venation in this region, but also has the base of CuA2 strongly flexed. The male genitalia are also distinctive, whilst showing the generic features to some extent. The saccus is only slightly expanded and square. The valves are short, the saccular process triangular, slightly divided apically, but characteristically spined. The aedeagus vesica has a central cornutus and a more distal comb of much smaller ones.
