Type material. Holotype: ɗ, CHINA: Mt. Fanjing [27°55'N, 108°41'E], Guizhou Province, 530 m, 2.vi.2002, coll. Xinpu Wang, genitalia slide no. FXM06054.
Diagnosis. This species is similar to T. acropercna Meyrick in the male genitalia, but can be distinguished from the latter by the valva, which is pointed at the apex and concave beyond the sacculus ventrally, and by the phallus, which is about twice as long as the saccus.
Description. Adult ( Fig. 5 View FIGURES 1 – 7 ): Wing expanse 14.0 mm. Head white, with appressed scales on frons and long rough scales between antennae. Antenna with scape white, flagellum pale yellow. Labial palpus white, porrect. Thorax and tegula snow white. Forewing white, sparsely tinged with brown; costal margin with basal 1/5 dark brown; brown spot at middle of cell and at 3/5 of fold respectively; cilia white with dark brown tip. Hindwing pale brownish yellow; cilia silvery white. Legs white except tarsi somewhat pale yellowish; mid tibia with a pale yellow spot at outside distally; hind tibia with a black dot at apex on either side.
Male genitalia ( Fig. 12 View FIGURES 12 – 16 ): Socius narrow in basal half, dilated from middle to about 3/4, then narrowed to pointed end, with a short spine at apex. Tuba analis membranous. Ventral plate of gnathos small, somewhat rounded. Valva narrow, obliquely uprising, finely haired; broad at base, gradually narrowed to roundly pointed apex, bent inward; costa weakly sclerotized, gently curved at middle; inner process of proximodorsal part a short narrow bar; ventral margin concave inward beyond sacculus. Sacculus short and narrow. Saccus narrow, with posterior 2/5 V-shaped, anterior 3/5 straight, slightly narrowed to rounded apex. Phallus long, about twice length of saccus, slender and curved; dorsal margin with four large teeth medially, ventral margin dentate from middle to apex.
Female: Unknown.
Distribution. China (Guizhou).
Etymology. The specific name is derived from the Latin prefix acri-, and valvatus, referring to the apically pointed valva.
