Redescription. Adult ( Fig. 7 ). Wingspan 9.0–14.0 mm. Head white. Labial palpus white mixed with brown scales; second segment blackish brown in basal half, scales fluffy apically; third segment with black rings at distal 1/3 and before apex, shorter than second. Antenna with scape white, mixed with brown scales; flagellum alternately brown and yellowish white. Thorax and tegula grayish white, tegula deep yellow at base. Forewing ground color white, suffused with brown scales, with indistinct tiny black dots before apex; markings black: costa with spot near base, at 1/3 and 3/5 respectively, spot near base smaller; discal and discocellular spots small, sometimes indistinct; fold with spot overlaid with raised scales at 2/5, with raised white scales mixed with brown at 2/3; dorsum with a large diffusion at 1/3; tornal spot with raised scales; cilia grayish white, mixed with blackish brown. Hindwing grayish brown; cilia yellowish brown. Legs yellowish white, with brown dots, tarsi with each tarsomere black apically.

Male genitalia ( Fig. 17 ). Eighth sternum subtrapeziform, anterior margin protruded. Uncus subquadrate; posterior margin almost straight, with a notch at middle. Gnathos with anteromedian process conical. Tegumen furcate from beyond middle. Glandiductor symmetrical, broadened basally, strongly curved near base, longer than tegumen-uncus complex. Valva widened mesially; outer lobe short, digitiform, bearing several setae at apex; inner lobe stout, longer than outer lobe. Juxta slightly expanded triangularly at base, narrow mesially, rectangularly protruded outward distally; apex pointed, slightly hooked. Vinculum and saccus not distinctly divided, subrectangular. Aedeagus about 3/4 length of tegumen-uncus complex, basal half stout, distal half slender, slightly curved mesially, distal 1/3 obliquely truncate.

Female genitalia ( Figs. 27 , 34 ). Eighth sternum with posterior margin straight, concave mesially, sparsely setose. Apophyses posteriores about two times length of apophyses anteriores. Ostium bursae with lateral lobes sclerotized, triangularly produced. Ductus bursae about same length as corpus bursae, with an elongate rhombic sclerite at base. Corpus bursae ovate; signum semielliptical, slightly concave on anterior margin, spines anterolateral.

Diagnosis. This species is characterized in the male genitalia by the subrectangular uncus with a small notch on the posterior margin mesially, the valva with a digitiform outer lobe, and the aedeagus about 3/4 the length of the tegumen-uncus complex; in the female genitalia by the lateral lobes of the ostium bursae triangularly produced, and the ductus bursae with an elongate rhombic sclerite at base.

Distribution. China (Gansu, Hainan, Heilongjiang, Henan, Hubei, Shanxi, Tianjin, Zhejiang), Korea, Japan.
