Type material. CHINA, Xizang: Holotype ♁, Lulang Town (29.77°N, 94.74°E), 3308 m, 21.VIII.2018, leg. MJ Qi, slide No. LHY21769.

Diagnosis. The new species can be distinguished from its congeners in the male genitalia by the tegumen with a long, rod-shaped process medially at each side, and the valva roundly produced ventrobasally.

Description. Adult (Fig. 5). Wingspan 18.5 mm. Head white. Antenna white; flagellum ringed with dark brown dorsally. Labial palpus dark brown on outer surface, white on inner surface. Thorax and tegula dark grey, mottled with white. Forewing white; costal margin with basal 1/4 dark brown, distal 1/4 brown; subcostal line greyish brown, about 1/4 length of forewing; costal bar dark brown, from distal 1/3 of costal margin oblique to apex; dorsum with a greyish brown speckle formed by dense greyish brown scales diffused from base to basal 1/6; elongate subtriangular dark greyish brown patch edged with dark brown scales from between basal 1/6 and middle of dorsum narrowed obliquely outward to distal 2/5 of wing approaching to vein R 5, dark brown stripe from its apex widened towards apex of forewing; subterminal line dark brown, extending from distal 1/3 of dorsum to apex, with dark greyish brown scales beyond its base; fringe brown along costal margin, white mottled with brown along termen. Hindwing greyish brown; fringe greyish brown in basal half and white in distal half, except pale grey along basal half of dorsum. Legs white; foreleg dark brown ventrally, fourth and fifth tarsomeres dark brown; tibia and tarsus of foreleg with dense white scales dorsally; fourth and fifth tarsomeres of midleg dark brown dorsally; fourth tarsomere of hindleg dark brown dorsally.

Abdomen (Fig. 11a). Eighth abdominal sternite of male trapezoid, posterior margin 2 times width of anterior margin, slightly concave laterally.

Male genitalia (Fig. 11). Uncus stout, slightly narrowed to rounded apex. Socius slightly widened medially, with three rings of fringed sensillae in distal 1/3. Tegumen emarginated in triangle anteriorly, with a long, rod-shaped process medially at each side; anterolateral arm long, strongly curved at posterior 1/4. Ventral plate of gnathos fan-shaped; anterior margin heavily sclerotized and with a small mastoid medial process. Valva narrow and subparallel-sided from near base to before obtused apex, roundly produced ventrobasally; dorsoproximal process quadrate, slightly concave on inner margin. Saccus uniformly slender, except dilated from anterior 1/5 to apex. Aedeagus slender, strongly bent near base, narrow from near base to middle, slightly wider from 1/2 to distal 1/4, then tapered to apex, spinous in distal half; basal scape oval.

Female unknown.

Distribution. China (Xizang).

Etymology. The specific epithet is derived from the Latin longi- and processus, referring to the long, rod-shaped process of the tegumen.
