Diagnosis. This new species is similar to T. cambodiana Park, 2013 in both appearance and male genitalia. It can be distinguished in the male genitalia by the juxta with a long horn at middle on the posterior margin, and the aedeagus with a single banded cornutus; in T. cambodiana, the juxta is absent of a horn at middle on the posterior margin, and the aedeagus has three plate-shaped cornuti (Park et al. 2013: 2296, fig. 3M‒O).
Description. Adult (Fig. 8). Wingspan 17.5‒19.0 mm.
Head dark brown, with pale yellow scales laterally. Antenna pale yellow, scape tinged with brown, flagellum ringed with dark brown. Labial palpus dark brown except orange white on inner surface of second palpomere and dorsobasally on third palpomere, third palpomere as long as second palpomere.
Thorax and tegula dark brown. Forewing with costal margin nearly straight except slightly arched in basal 1/4, apex roundly produced, termen shallowly concave; basal 1/3 dark brown, outer margin sinuate, edged with black scales; distal 2/3 yellowish brown, with dense dark brown scales distally; costal spot pale yellowish brown, at distal 1/5; discocellular stigmata black, doubled, small, rounded; subterminal fascia pale yellowish brown, running from costal spot oblique inward to dorsum, nearly parallel to termen, edged with dense dark brown scales; termen with six black dashes; fringe brown, basal line brownish yellow. Hindwing and fringe grey; fringe with an orange white basal line. Legs with femora and tibiae dark brown, tarsi pale yellow.
Male genitalia (Fig. 26). Uncus wide at base, narrowed to acute apex. Gnathos with mesial process straight, wide at base, tapered to apex, curved ventrad slightly before apex. Valva broad basally before cucullus; cucullus expanded ventrad basally, narrowed to rounded apex, arched ventrally; costal bar free basally, arched; costa straight distally; sacculus relatively broad in basal half, slender distally, gently arched ventrally. Vinculum broad, rounded and with two small protuberances on anterior margin. Juxta elliptical, posterior margin with a large horn at middle longer than juxta, anterior margin deeply concave in U shape at middle and heavily sclerotized along margins of concavity. Aedeagus as long as valva, strongly arched in C shape, wide at base, slightly narrowed to basal 1/3, distal 2/3 tubular; cornutus banded with an apical spine, about 2/3 length of aedeagus.
Female genitalia (Fig. 43). Eighth abdominal sternite obtuse on posterior margin.Apophyses posteriores slightly longer than apophyses anteriores. Antrum membranous. Ductus bursae slightly longer than corpus bursae; ductus seminalis narrower, arising from about posterior 1/4 of ductus bursae. Corpus bursae elliptical; signum situated posterior to middle, rounded, incised at middle on posterior margin, with a furrow along transverse midline.
Distribution. China (Hainan).
Etymology. The specific epithet is derived from the Latin long- and cornis, referring to the long horn present in the juxta on its posterior margin in the male genitalia.
