Diagnosis. This new species is similar T. rhaphisodes Park, 2019 in both appearance and male genitalia. It can be distinguished by the uncus nearly straight at apex, the cucullus subrectangular, and the aedeagus glabrous; in T. rhaphisodes, the uncus is bilobed apically, the cucullus is widened distally, and the aedeagus is filled with numerous piliform setae (Park 2019: 302, fig. 1).
Description. Adult (Fig. 14). Wingspan 14.5‒18.0 mm.
Head brown, frons orange white. Antenna with scape brown; flagellum orange white, ringed with dark brown. Labial palpus with second palpomere orange white on inner surface, brown on outer surface; third palpomere orange white dorsally, dark brown ventrally, as long as second palpomere.
Thorax and tegula brown. Forewing with costal margin slightly arched, apex obtuse, termen shallowly concave; ground color dark brown; costal spot orange white, small, before distal 1/4; discocellular stigma blackish brown, obscure; fringe greyish brown, basal line pale brownish yellow. Hindwing and fringe pale greyish brown; fringe with an orange white basal line. Legs orange white except femur and tibia of foreleg brown ventrally, femur and tibia of hindleg brown totally, tarsi dark brown dorsally at middle of first tarsomere and at base of remaining tarsomeres.
Male genitalia (Fig. 32). Uncus subrectangular, slightly narrowed lateromedially, apex nearly straight. Gnathos with mesial process wide at base, narrowed to middle, slightly expanded beyond, thereafter abruptly narrowed to pointed apex, curved ventrad at distal 2/5 by a right angle. Valva broad and parallel-sided basally, narrowed to cucullus; cucullus subrectangular, apex broadly rounded, gently arched ventrally; costa obtusely arched basally, concave medially, straight distally; sacculus banded, reaching cucullus apically, straight ventrally. Vinculum narrow, rounded on anterior margin. Juxta subquadrate, shallowly concave on posterior margin, obtuse on anterior margin, protuberant along longitudinal midline; lateral lobe papillary, setose, from about posterior 1/4. Aedeagus nearly as long as valva, broad in basal half, narrowed in distal half, with a band of granules beyond middle; cornutus absent.
Female genitalia (Fig. 47). Eighth abdominal sternite deeply incised at middle on posterior margin, forming two triangular lateral lobes. Apophyses posteriores slightly shorter than twice length of apophyses anteriores. Antrum membranous. Ductus bursae dilated medially, with several conic spines medially; ductus seminalis slender, helical, arising from ductus bursae posterior to middle, with dense granules on inner wall. Corpus bursae elliptical, granulose on surface; signum large, drop-shaped, about half length of corpus bursae, denticulate, lateromedially with two concavity bearing larger spines.
Distribution. China (Zhejiang).
Etymology. The specific epithet is derived from the Latin stilliformis, referring to the drop-shaped signum of the corpus bursae in the female genitalia.
