(Figs 9, 27)

Type material. CHINA, Yunnan: Holotype ♂, Yexianggu (22°10′N, 100°52′E), Xishuangbanna, 762 m, 9.VII.2015, leg. KJ Teng & X Bai, slide No. YS19295. Paratypes (21♂): 12♂, same data as holotype except dated 9, 12.VII.2015, leg. KJ Teng & X Bai; 8♂, same locality as holotype, 17‒20.VII.2014, leg. KJ Teng et al., slide Nos. YS20135, YS20242; 1♂, Damanlu Village, Menghai County, 1128 m, 2.VIII.2019, leg. KJ Teng, C Liu & AL Wang.

Diagnosis. This new species is similar to T. alterniella Park, 2021 in appearance. It can be distinguished in the male genitalia by the cucullus narrowed to apex, and the juxta with a pair of subtriangular posterolateral lobes; in T. alterniella, the cucullus is widened to apex, and the posterolateral lobes of the juxta is digitate (Park & Bae 2021: 108, fig. 3c).

Description. Adult (Fig. 9). Wingspan 23.0‒23.5 mm.

Head brown except white on frons and laterally. Antenna with scape dark brown except white along anterior and posterior margins; flagellum white, ringed with blackish brown, orange white apically. Labial palpus dark brown except white at apex of second palpomere, third palpomere as long as second palpomere.

Thorax and tegula brown. Forewing with costal margin slightly arched, apex triangularly produced, termen shallowly concave; ground color brown; costal spot white, wedge-shaped, before distal 1/4; subterminal line white, running from costal spot discontinuously to dorsum before tornus, arched outward; distal 1/5 of costal margin and termen decorated with dark brown and white scales; fringe brown, basal line orange white. Hindwing and fringe pale greyish brown; fringe with an orange white basal line. Legs with femora and tibiae brown, tarsi white except dark brown at middle of first tarsomere and at base of second and third tarsomeres.

Male genitalia (Fig. 27). Uncus wide at base, slightly narrowed to basal 2/3, thereafter widened to apex, apex shallowly concave medially. Gnathos with basal plate roundly produced posteriorly; mesial process wide at base, tapered to apex, gently arched. Valva extending obliquely ventrad, wider at base, slightly narrowed to cucullus; cucullus about 2/5 length of valva, narrowed to broadly obtuse apex, nearly straight ventrally; costa straight basally, shallowly concave distally; sacculus wide at base, narrowed to cucullus, straight ventrally. Vinculum narrow. Juxta rectangular, longer than wide, slightly widened anterolaterally, notched at middle on posterior margin, coarse on lateral margin, produced at middle on anterior margin; posterolateral lobe elongate triangular, about half length of juxta, extending obliquely inward, apex rounded, setose. Aedeagus slightly longer than valva, arched, broad basally, tapered to apex, apex produced dorsad forming a short process; cornuti consisting of dense strong spines from basal 1/3 to before apex forming an ellipse.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the Latin obliquus, referring to the oblique valva in the male genitalia.
