Patagium and tegula brownish gray, with pale gray scales at tip. Femur of forelegs mixed with fuscous and white; tibia fuscous, middle part with white scales; tarsus fuscous, ringed with pale gray at tip of each segment. Midlegs with femur and tibia almost white, slightly mixed with fuscous. Hindlegs with femur white, basal part slightly fuscous; tibia fuscous, mixed with grayish white scales. Ground color of forewing fuscous, antemedial line absent, basal 1/3 of costal area with one rounded white spot; postmedial line white and sinuous, inner side with one white spot in costal area; one thin and short stick-shaped spot near middle of dorsum; terminal line pale gray; fringe fuscous. Hindwing with ground color grayish brown; terminal line pale brownish gray; fringe pale gray.

Male genitalia (Fig. 5). Uncus subtriangular, rounded at top, lateral sides straight, covered with hairs near top; gnathos about 1/2 length of uncus, hooked at tip; transtilla with rectangle-shaped connection on top, terminal margin flat; valva with rounded apex, costa sclerotized, gradually slender from base to distal part, distal process separated with valva; sacculus about 2/5 length of valva; juxta U-shaped, lateral lobes subtriangular; vinculum Ushaped, saccus flat; aedeagus rod-shaped, rounded at base, about 4/5 length of valva, with wrinkles and minute spines located in middle; the shape of 8th sternite shown in Fig. 5a.

Female genitalia ( Figs. 8 , 12 ). Papillae anales triangular, with length same as width; 8th abdominal segment with length same as width, anterior edge convex; apophyses posteriores about 1.2 times as long as apophyses anteriores, both apophyses slightly enlarged at base, apophyses posteriores reaching anterior edge of the 8th abdominal segment; antrum funnel-shaped; ductus bursae membranous, anterior 2/5 enlarged distinctly, 2 times as long as apophyses anteriores; corpus bursae oval, with length less than 2 times of width, corpus bursae about 5/6 length of ductus bursae, signum ( Fig. 12 ) crescentic-shaped, located at anterior 1/3 of corpus bursae; ductus seminalis from anterior part of corpus bursae.

Diagnosis. This species resembles A. korbi ( Caradja, 1910) ( Figs. 4 , 7, 11, 15), but can be distinguishied by the following characters: forewing with one rounded spot at basal 1/3 of costal area; white streak near middle of dorsum rather slim; in male genitalia, uncus subtriangular, lateral sides straight; gnathos rather stout; aedeagus rodshaped, about 4/5 length of valva; in female genitalia, length of 8th abdominal segment same as width, anterior edge slightly convex; apophyses posteriores reaching anterior edge of the 8th abdominal segment; anterior 2/5 of ductus bursae enlarged; length of corpus bursae less than 2 times of width, corpus bursae about 5/6 length of ductus bursae. As for A. korbi , forewing with one spot at base of costal area; white streak near middle of dorsum rather bold; in male genitalia, uncus with lateral sides concave; gnathos slim, costa with distal part bulged; aedeagus about 1/2 length of valva, tube-shaped, bulged at middle; in female genitalia, the 8th abdominal segment with length longer than width, anterior edge w-shaped; apophyses posteriores not reaching anterior edge of the 8th abdominal segment; anterior 3/4 of ductus bursae enlarged; length of corpus bursae about 2 times of width, corpus bursae same length as ductus bursae.

Distribution. China (Jilin Prov.).

Etymology. The species is named for the type locality, Jilin Province, Yanbian Autonomous Prefecture.
