Diagnosis.

Wingspan: 13–15 mm.

Transverse lines: well marked, brown; basal, antemedial, and postmedial lines marked with a black spot by costa.

Reniform: distinct, elongated, black.

Hindwing: dark brown.

Underside: unicolorous brown.

Abdomen: brown, with a black dorsal crest on first segment; male with a long black and brown anal tufts.

Male genitalia.

Saccus: short, V-shaped.

Vinculum: short.

Tegumen: very long.

Fultura superior: fused with tegumen by a triangular process on left side.

Tergite and sternite: indistinct.

Costa: a prominent thorn at base of costa.

Sacculus: symmetrical; apical process; small medial elevation.

Ampulla: slightly asymmetrical; golf-club like, apically smoothly rounded; a hump basally on left ampulla. Pollex : small triangular, with long hair-like setae.

Digitus: symmetrical; long, narrow, curved, pointed apically.

Phallus: extremely long, broadest by ductus ejaculatorius, abruptly coiled clock-wise at 2/3, slightly tapering towards apex, with slight subapical bend; coecum very long.

Female genitalia.

Ovipositor: quadrangular.

Anterior apophyses: length equal to that of posterior apophyses.

8 th abdominal segment: very narrow, ventrally fused with 7 th segment.

7 th abdominal segment: heavily sclerotised; position of ostium at 2/3.

Antrum: short, tapered, heavily sclerotised, as wide as long, on anterior side with a prominent V-shaped crest (seen best on plate 21, fig. 6).

Ductus bursae: membranous; 2¼ X as long as corpus bursae.

Appendix bursae: arising anteriorly from ductus bursae immediately after antrum.

Corpus bursae: globular.

Differential diagnosis.

The male genitalia resemble those of T. kampungi , T. orientis , and T. conscitulana , but differ from them in having a longer costal process than T. kampungi and T. conscitulana but a shorter one than T. orientis ; a broader dorsal ampulla than T. conscitulana and T. orientis but a narrower one than T. kampungi ; and phallus subapically more bent that in these other three species. The female genitalia have the stortest antrum and is the only one known to have a dorsal crest.
