(Figs 1, 19, 37)

Type material. CHINA, Yunnan: Holotype ♂, Pukawang Village (27°50′N, 98°19′E), Gongshan County, 1335 m, 12. VI.2017, leg. KJ Teng et al., slide No. YS 20034 . Paratypes (19♂ 19♀): 17♂ 19♀, same data as holotype except dated 5‒12. VI.2017, slide Nos. YS 19721 ♂, YS20263 ♀, YS20321 ♀; 2♂, Qinlangdang, Gongshan County, 380 m, 28, 30. V.2017, leg. KJ Teng et al., slide No. YS 20213 .

Diagnosis. This new species is similar to T. candida Park, 2008 in both appearance and male genitalia. It can be distinguished by the forewing with R 5 present, the fringe of the forewing greyish brown, and the aedeagus without a cornutus; in T. candida, the R 5 of the forewing is absent, the fringe of the forewing is creamy white, and the aedeagus has cornuti (Park 2008a: 364, fig. 20).

Description. Adult (Fig. 1). Wingspan 17.5‒20.0 mm.

Head dark brown, with brownish yellow scales laterally. Antenna with scape dark brown except pale brownish yellow along posterior margin; flagellum with basal 2/3 brownish yellow ringed with dark brown, distal 1/3 pale yellow. Labial palpus brown, third palpomere slightly longer than second palpomere.

Thorax and tegula blackish brown. Forewing slightly widened distally, costal margin slightly arched, apex obtusely rounded, termen shallowly concave; ground color blackish brown; discal stigma black, small, rounded; plical and discocellular stigmata black, larger; fringe greyish brown. Hindwing and fringe pale greyish brown; fringe with an orange white basal line. Legs pale yellow except femora and tibiae dark brown ventrally.

Male genitalia (Fig. 19). Uncus wide at base, narrowed to middle, distal half clubbed. Gnathos with basal plate triangularly produced posteriorly; mesial process wide at base, narrowed to basal 3/5, thereafter abruptly slender to pointed apex, curved ventrad at distal 2/5 by a right angle. Valva broad basally, narrowed to cucullus, with a large ventral zone of spinules before cucullus; cucullus extending obliquely dorsad, uniform basally, expanded ventrad medially, narrowed from middle to rounded apex; costa convex basally, concave medially, obliquely straight distally; sacculus wide at base, ill-defined distally, ventral margin obtusely arched. Vinculum nearly straight on anterior margin. Juxta subquadrate, straight on posterior margin, concave medially on lateral margin, obtusely produced medially on anterior margin; with a large rectangular process from near posterior margin on ventral surface; posterolateral lobe nearly as long as juxta, horn-shaped, wide at base, narrowed to basal 1/3, mesial 1/3 uniform, distal 1/3 slender, pointed at apex. Aedeagus about 3/4 length of valva, broad basally, narrowed to obtuse apex, arched, with some granules distally; cornutus absent.

Female genitalia (Fig. 37). Eighth abdominal sternite deeply incised in V shape on posterior margin, forming two large semiovate lateral lobes. Apophyses posteriores about 1.5 times length of apophyses anteriores. Antrum heavily sclerotized, quadrate, spiculose. Ductus bursae shorter than corpus bursae, as wide as antrum, with dense spines running from about posterior 1/5 to anterior 1/5; ductus seminalis narrower, twisted, arising from posterior 1/4 of ductus bursae. Corpus bursae large elliptical; signum situated at middle, subrhombic, posterior half heavily sclerotized, anterior half moderately sclerotized.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the Latin acuminatus, referring to the distally slender posterolateral lobes of the juxta in the male genitalia.
