( Figs 18 , 36 , 49 )

Type material. CHINA, Zhejiang: Holotype ♂, Sanmuping (30°22′N, 119°26′E), Mt. Tianmu , 789 m, 14.VII.2014, leg. AH Yin, XM Hu & QY Wang, slide No. YS20115 . Paratypes (1♂ 4♀): 1♀, same data as holotype, slide No. YS 20317 ; 1♂, Xiguan, Mt. Tianmu , 566 m, 17.VII.2014, leg. AH Yin, XM Hu & QY Wang, slide No. YS 20342 ; 3♀, Qianjiangyuan, Mt. Tianmu , 866 m, 8‒9.VII.2014, leg. AH Yin, XM Hu & QY Wang.

Diagnosis. This new species is diagnostic in the male genitalia by the cucullus with a large straight horn ventrally. It is similar to T. atomata sp. nov. in both appearance and genitalia, and the differences between them are stated in the diagnosis of the latter species.

Description. Adult ( Fig. 18 ). Wingspan 25.0‒25.5 mm.

Head brown, orange white on frons and laterally. Antenna with scape brown, flagellum pale yellow. Labial palpus with second palpomere pale yellow on inner surface, brown on outer surface; third palpomere pale yellow dorsally, brown ventrally, as long as second palpomere.

Thorax and tegula brown. Forewing with costal margin slightly arched, apex roundly produced, termen shallowly concave; ground color brown; costal spot pale yellow, small, wedge-shaped, before distal 1/4; discocellular stigma dark brown, obscure; subterminal line pale yellow, obscure; fringe pale greyish brown, basal line orange white. Hindwing and fringe greyish brown; fringe with an orange white basal line. Legs pale yellow except femora and tibiae of fore- and hindlegs brown ventrally, tarsi dark brown dorsally at middle of first tarsomere, and at base of remaining tarsomeres.

Male genitalia ( Fig. 36 ). Uncus broad basally, narrowed to narrowly rounded apex, bent ventrad distally. Gnathos with basal plate quadrate, emarginated on posterior margin; mesial process elongate, falcate. Valva relatively narrow at base, widened to before middle, thereafter abruptly constricted in its distal 2/3; cucullus bent obliquely ventrad slightly, about 1/3 length of valva, slightly widened medially, narrowed to a subacute apex, ventral margin with a large, straight horn-shaped process, longer than twice of basal width; costa obtusely arched in basal 2/3, concave beyond, arched distally; sacculus narrowly banded in basal half, almost right-angled and bearing a cluster of piliform setae ventromedially, narrowed obliquely dorsad from middle to constriction. Vinculum narrow, rounded on anterior margin. Juxta large, subrectangular, widened anterolaterally, shallowly concave on posterior margin, imbricated at middle on anterior margin, with two pairs of lateral lobes: posterior pair large horn-shaped, extending obliquely inward, fused apically forming an oval circle, longer than maximum width of juxta; anterior pair arising from base of posterior lobe, slightly widened to straight apex, apex with 2‒4 spines ( Fig. 36a ), outer margin produced subbasally. Aedeagus slightly shorter than valva, strongly arched, narrowed from base to obtuse apex; cornuti consisting of a weakly sclerotized plate at basal 1/3, and numerous spines running from basal 1/3 to before apex.

Female genitalia ( Fig. 49 ). Eighth abdominal sternite triangularly concave at middle on posterior margin, forming two lateral lobes, with a heavily sclerotized, subtriangular plate anterior to concavity.Apophyses posteriores slightly shorter than twice length of apophyses anteriores. Ductus bursae longer than corpus bursae, posterior 2/3 sclerotized, anterior 1/3 membranous and wrinkled; ductus seminalis slender, arising from about posterior 1/3 of ductus bursae. Corpus bursae ovate; signum situated posterior to middle, elliptical, densely denticulate.

Distribution. China (Zhejiang).

Etymology. The specific epithet is derived from the type locality.
