( Plate 1 , figure 4, 5; male genit. plate 12, figure 2)

Material examined.

Holotype: male, Thailand mid-west, by Kanchannaburi , River Kwai Resotel, 19–22.vii.2003, leg. M. Fibiger. Coll. MF, to be deposited in ZMUC.

Paratypes: 2 males. 1 male, Thailand N, 30 km N Mae Hong Son, Karen village , 1100 m, 16.vii.2003, leg., coll. and genit. prep. 5003 MF ; 1 male Thailand S, Phang Nga Khao Sok Nat. Park , NE Phang Nga town, 5.vii.2005, leg. D. Nilsson, genit. prep. 5671 M. Fibiger. Coll. DN .

Diagnosis.

Wingspan: 13–14 mm.

Transverse lines: all lines brown, indistinct; antemedial and postmedial lines with a black spot by costa. Reniform: indistinct, almost invisible.

Hindwing: dark brown

Underside: unicolorous brown.

Abdomen: brown, with black crest on first segment; male with long black to brown anal tuft (see plate 1, fig. 5)

Hindleg: with prominent long scent-brush (plate 1, fig. 5).

Male genitalia.

Saccus: short, slightly rounded.

Vinculum: short.

Tegumen: extremely long.

Fultura superior: left side sclerotised, fused with tegumen, forming a small triangular process.

Tergite and sternite: indistinct.

Sacculus: with heavily sclerotised, apical cone-like process on both valves.

Ampulla: slightly asymmetrical, golfclub-like, smoothly rounded apically.

Pollex : triangular, short, with long hair-like setae.

Digitus: long, narrow, evenly curved and pointed apically on both valves.

Juxta: higher than wide.

Anellus: ventral left side fused with juxta.

Phallus: extremely long, broadest by ductus ejaculatorius, coiling clock-wise, bent, slight tapering towards apex; coecum short and pointed.

Differential diagnosis.

The male genitalia resemble those of the next two species: T. butani and T. indiai , but differ from these species in having longer saccular processes and a much longer, narrower phallus.
