Diagnosis. The species can be distinguished from congeners by the dark fuscous forewing with the distal half strongly mixed with brownish grey. The male genitalia of T. fuscalata sp. nov. are most similar to those of T. immaculata sp. nov., but the uncus is broader and there are fewer tegumen tubercles than in the latter species. Also, the anellus lobes of T. fuscalata are fusiform, constricted basally and apically, whereas those of T. immaculata sp. nov. are ovate. In the female genitalia, the boomerang-shaped signum is distinctive.

Description. Adult (Fig. 49). Head: Vertex pale greyish brown, frons grey to dark fuscous. Labial palpus pale greyish brown except palpomere III fuscous. Antenna with scape pale greyish brown to dark fuscous; flagellum dark fuscous, sometimes with dorsal surface slightly suffused with grey, male cilia as long as diameter.

Thorax: Dark fuscous, except posterior half pale brown. Tegula dark fuscous, sometimes tinged with pale brown posteriorly. Wingspan 7.5–10.0 mm; forewing with basal 1/2 dark fuscous to black, near base usually pale greyish brown below fold; distal 1/2 pale greyish brown, strongly mixed with fuscous toward apex, with two indistinct lines at anterior 1/3 of wing and on fold, respectively, both merged with fuscous suffusion near apex; fringe scales dark grey to dark fuscous. Hindwing and fringe scales dark fuscous. Legs pale greyish brown; fore coxa sometimes strongly mixed with grey; mid-tibia dark grey along dorsal margin, with a fuscous spot at distal 1/3 of outer surface; hind tibia broadly dark fuscous at base, at middle and at apex.

Abdomen (Fig. 7): Male coremata slightly shorter than sternum VIII; sternum III–VI well-sclerotized, sternum VIII rounded. Male genitalia (Fig. 68) with uncus short, sub-pentagonal, with a medial ridge on ventral surface. Gnathos hook short, sharply pointed apically. Tegumen approximately 6 times as long as uncus; with a bundle of tubercles situated at middle of ventral surface, each tubercle ampulliform (Fig. 29). Valva slender, slightly curved inward, spatulate distally.Anellus lobe somewhat fusiform, approximately 1/5 length of valva; apical bristle slightly shorter than anellus lobe. Juxta with inner margin broadly convex at middle. Vinculum broad, posterior margin convex. Saccus short and broad, sub-triangular. Aedeagus with basal 2/5 dilated, slender and nearly straight distally. Female genitalia (Fig. 86) with papillae anales simple and setose. Apophyses anteriores approximately 1/2 length of apophyses posteriores. Tergum VIII divided into two sclerites; sternum VIII nearly straight posteriorly, broadly convex anteriorly, weakly sclerotized near ostium bursae and near posterior margin. Ostium bursae near anterior margin of sternum VIII. Ductus bursae slender, broadening toward corpus bursae, ductus seminalis arising from near base. Corpus bursae elongate-ovate, about as long as ductus bursae; signum long, slender, boomerang-shaped or elongate triangular, situated in posterior half of corpus bursae.

Distribution. China (Xizang, Yunnan).

Etymology. The species name is derived from the Latin fusco- (dark) and alatus (winged), referring to the dark fuscous forewing.
