Diagnosis. This species is similar to T. tylostegalis (Hampson) externally, but can be distinguished by the valva with a large elliptical projection medially; the smooth dorsal margin of the sacculus inflated triangularly at middle; the phallus with one short and stout spinelike and one dentate cornuti. In T. tylostegalis the valva has a small triangular projection medially; the dorsal margin of the sacculus bears small teeth; and the phallus has three spinelike cornuti.
Description. Male ( Fig. 5 View FIGURES 1 – 5 ). Wing span 19.0–22.0 mm. Frons yellowishwhite except fuscous anteriorly. Antenna with ventral cilia about as long as flagellomere diameter in male, minute in female. Labial palpus white or yellowishwhite, 2nd segment fuscous or brown dorsally and distally, 3rd segment pale yellow. Thorax yellowishwhite dorsally, each segment with a fuscous blotch. Patagium and tegula yellowishwhite or pale yellow, mottled brown. Forewing pale yellow diffused with brown, with fuscous or black patches at base; discoidal stigma blackishfuscous; lines blackishfuscous, broader and darker on costa; antemedial line slightly excurved; postmedial line sinuated as in T. pectinata ; a series of blackishfuscous spots along terminal margin. Hindwing yellowishwhite, with large fuscous patch at base; discoidal stigma dark fuscous, claviform; a broad region consisting of brown patches extending from middle of inner margin obliquely to costal and terminal margins; some fuscous spots placed along terminal margin. Cilia of both fore and hindwings light brownishyellow, paler distally. Abdominal segment 1 white with two fuscous patches, the remaining segments pale yellow and suffused with fuscous on 2nd–5th segments dorsally; ventral surface white or yellowishwhite.
Male genitalia ( Figs. 12 View FIGURES 8 – 12 , 17 View FIGURES 13 – 17 ). Uncus height greater than basal width. Valva gradually narrowed from base to apex, with large, median elliptical projection bearing dense small spines anteriorly, and with sclerotized flat process near apex of sacculus. Sacculus concave at basal 1/3 on dorsal margin, inflated triangularly at middle, then gradually narrowed to subapex, distally inflated triangularly. Saccus short and broad, triangular, bluntly rounded on anterior margin. Juxta circular, concave on posterior margin, protruding posterolaterally. Phallus with one short and stout spinelike and one dentate cornuti.
