Adult (Fig. 5). Wingspan 14.5–17.0 mm. Head white. Labial palpus grayish white except brown outer surface of first and second segments, second segment about 1.5 times length of diameter of eye; third segment gradually narrowed distally. Antenna with scape yellowish white, flagellum alternately brown and yellowish brown on dorsal surface, yellow on ventral surface. Thorax and tegula yellowish white, tegula with grayish brown scales basally. Forewing pale yellowish brown, becoming deep yellowish brown from base toward inner margin of distal patch; distal patch subelliptical, yellow with scattered brownish yellow scales, inner margin slightly arched inward; cilia yellowish brown in basal 1/4, yellow from 1/4 to middle, grayish yellow in distal half. Hindwing brown, cilia grayish yellow basally, grayish brown distally. Foreleg yellowish white to white, tibia and tarsus with brown markings; mid and hind legs yellow, tarsi deep yellow distally, with brown scales or rings.
Male genitalia (Fig. 11). Uncus broad at base, narrowed to before middle where it is constricted inward, then gradually widened to about basal 2/3, with lateral sides bluntly protruded; distal 1/3 protruded subtriangularly, rounded apically. Gnathos subtriangular, narrowed basally, widened toward anterior margin; anterior margin almost straight, with dense pecten stretching backward. Valva shorter than tegumen-uncus complex, slightly narrowed distally, rounded apically. Transtilla dilated distally, weakly joined medially. Sacculus subrectangular; apex slightly triangularly elongate dorsoapically. Vinculum narrowly banded, rounded anteriorly. Phallus stout, rounded apically.
Female genitalia (Fig. 16). Papillae anales subrectangular, slightly narrowed caudally, sparsely setose. Apophyses anteriores about same length as apophyses posteriores, furcate in basal 2/5. Eighth tergite straight on posterior margin; eighth sternite with both posterior and anterior margins deeply concave at middle, with setae. Antrum subrectangular, weakly sclerotized, with granules on inner surface. Ductus bursae about 2/5 length of corpus bursae. Corpus bursae subrectangular, with length about four times as long as width, inner surface with clustered granules around posterior corner on left; signum absent.
Diagnosis. This species is close to A. bicolor, but distinguishable by the uncus bluntly protruded laterally in basal 2/3 and rounded at apex, the subtriangular gnathos, and the valva shorter than the tegumen-uncus complex in the male genitalia. In A. bicolor, the uncus is triangularly protruded in basal 2/3 and angled at apex, the gnathos is approximately semioval, and the valva is longer than the tegumen-uncus complex in the male genitalia.
Distribution. China (Gansu, Guizhou, Jiangxi, Shanxi, Zhejiang, Taiwan), Indonesia, India (Li 2002).
Variations. Both the thorax and the tegula are grayish brown, the fore and hind wings are brown, and the distal patch of the forewing is deep yellow and nearly inverted triangular in the specimens collected in Shanxi. However, the genital structures are constant and the same as those from other localities.
