( Figs 15 , 33 )

Type material. CHINA, Yunnan: Holotype ♂, Jingpozhai (24°42′N, 97°24′E), Yingjiang County, 231 m, 2.VIII.2013, leg. SR Liu, YQ Wang & KJ Teng, slide No. LSR13240.

Diagnosis. This new species is similar to T. serpentina ( Diakonoff, 1951) and T. spectabilis sp. nov. superficially. It can be distinguished by the hindwing purplish brown entirely, the cucullus subacute at apex, and the aedeagus lacks cornutus; in the latter two species, the hindwing is pale-colored around apex, the apex of the cucullus is rounded, and the aedeagus bears cornuti.

Description. Adult ( Fig. 15 ). Wingspan 17.0 mm.

Head and antenna orange yellow. Labial palpus orange yellow, third palpomere as long as second palpomere.

Thorax and tegula orange yellow. Forewing with costal margin slightly arched, apex obtuse, termen oblique; ground color purplish brown, orange yellow at proximal base; costal margin with an orange yellow stripe from before middle to apex, slender medially, slightly widened distally; fringe orange yellow except purplish brown around tornus. Hindwing purplish brown; fringe greyish black. Legs orange yellow.

Male genitalia ( Fig. 33 ). Uncus wide at base, narrowed to subacute apex. Gnathos with mesial process wide at base, narrowed to basal 3/4, distal 1/4 slender, hooked. Valva broad basally, slightly narrowed to cucullus; cucullus slightly longer than half length of valva, expanded ventrad basally, narrowed to subacute apex, arched except slightly concave before apex ventrally; costa arched basally, concave medially, nearly straight distally; sacculus wide at base, narrowed to cucullus, straight ventrally. Vinculum narrow, obtuse on anterior margin. Juxta elliptical, sinuate on posterior margin, rounded on anterior margin. Aedeagus shorter than valva, stout, straight, wide at base, narrowed to straight apex, with granules in vesica; cornutus absent.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the Latin strigulosus, referring to the forewing with a costal stripe.
