(Figs 3, 21, 38)
Type material. CHINA, Yunnan: Holotype ♂, Qinlangdang (27°42′N, 98°16′E), Gongshan County, 380 m, 29. V.2017, leg. KJ Teng et al., slide No. YS 20133. Paratypes (90♂ 35♀): 46♂ 11♀, same data as holotype except dated 28. V ‒1. VI.2017, slide Nos. YS 20039 ♂, YS20367 ♀; 44♂ 24♀, Pukawang Village, Gongshan County, 5‒ 12. VI.2017, leg. KJ Teng et al., slide Nos. YS 19664 ♂, YS19665 ♀, YS20035 ♂, YS20256 ♀.
Diagnosis. This new species is similar to T. meyi Park, 2008 in both appearance and male genitalia. It can be distinguished by the greyish brown fringe of the forewing, in the male genitalia by the uncus elliptical dilated distally, in the female genitalia by the rectangular signum of the corpus bursae; in T. meyi, the fringe of the forewing is dark brown in basal 2/3 and creamy white in distal 1/3, the uncus is narrowed from base to apex (Park 2008: 368, fig. 32), and the signum is strawberry-shaped (Park 2008a: 370, fig. 45).
Description. Adult (Fig. 3). Wingspan 18.0‒21.5 mm.
Head dark brown. Antenna with scape dark brown except pale yellow along anterior and posterior margins; flagellum pale yellow, ringed with dark brown dorsally in basal 1/4. Labial palpus dark brown except pale yellow dorsally on third palpomere, second palpomere mixed with pale yellow scales on inner surface, third palpomere as long as second palpomere.
Thorax and tegula dark brown. Forewing with costal margin slightly arched, apex roundly produced, termen shallowly concave; ground color dark brown; costal spot pale orange, small, at distal 1/4; discal, plical and discocellular stigmata blackish brown, obscure; dorsal spot pale orange, weak, at distal 1/5; fringe greyish brown, basal line orange white. Hindwing and fringe dark brown; fringe with an orange white basal line. Legs pale yellow except femora and tibiae of fore- and hindlegs dark brown ventrally, tarsi dark brown dorsally at middle of first tarsomere and at base of remaining tarsomeres.
Male genitalia (Fig. 21). Uncus broad basally, constricted medially, elliptically dilated distally, apex rounded. Gnathos with mesial process wide at base, narrowed to middle, slightly expanded beyond middle, thereafter abruptly narrowed to pointed apex, curved ventrad beyond middle by a right angle. Valva broad basally, narrowed to middle, distal half parallel-sided, apex rounded; costa obtusely arched basally, straight distally; sacculus broad basally, ill-defined distally, obtusely arched ventrobasally. Vinculum narrow, obtuse on anterior margin. Juxta rectangular, wider than long, shallowly concave on posterior margin; with a horizontal cap-shaped process from near posterior margin; with a longitudinal flabellate flap along midline from apex of horizontal process to anterior margin; lateral lobe papillary, bearing several long setae, from near posterolateral corner. Aedeagus as long as valva, stout, arched, tapered from base to apex, apex heavily sclerotized, with a small dorsal process; cornuti consisting of a weakly sclerotized plate at basal 1/4 and a larger moderately sclerotized plate near apex.
Female genitalia (Fig. 38). Eighth abdominal sternite concave at middle on posterior margin. Apophyses posteriores about thrice length of apophyses anteriores. Lamella antevaginalis narrowly banded, subcrescent. Antrum membranous, funnel-shaped. Ductus bursae nearly as long as corpus bursae, broad, twisted twice, with a row of spines running from about posterior 1/6 to middle, with a diverticulum posterior to ductus seminalis; ductus seminalis narrower than ductus bursae, arising from about posterior 1/6 of ductus bursae, with dense denticles and granules on inner wall. Corpus bursae ovate; signum large rectangular, slightly shorter than half length of corpus bursae, densely denticulate, notched at middle on anterior and posterior margins, with a furrow along longitudinal midline from posterior margin to anterior margin.
Distribution. China (Yunnan).
Etymology. The specific epithet is derived from the Latin canaliculatus, referring to the signum of the corpus bursae with a furrow in the female genitalia.
