Type material. CHINA, Sichuan: Holotype ♁, Longcanggou (29.62ºN, 102.88ºE), Yingjing, 1405 m, 16.VII.2021, leg. S Yu et al., slide No. ZXJ20439. GoogleMaps
Diagnosis. The new species is similar to A. abditella Hannemann, 1959 in male genitalia, and can be distinguished by the dark brown forewing; by the valva not produced ventroapically and the cuiller with dense small spines distally in the male genitalia. In A. abditella , the forewing is pale yellow; the valva is produced ventroapically and the cuiller has a spine at apex. The new species is also similar to A. nivimacularis sp. nov., and the differences between them are stated in the diagnosis of the latter species.
Description. Adult ( Fig. 2 View FIGURES 1‒8 ). Wingspan 14.0 mm.
Head greyish brown, occiput yellowish brown. Labial palpus grey, basal two segments mixed with dark brown scales, second segment without protruding scales; third segment dark brown, with dense grey scales distally on dorsal surface. Antenna with scape dark brown on dorsal surface, dark brown basally and yellow distally on ventral surface, yellow on anterior and posterior margins; pecten yellow; flagellum dark brown.
Mesonotum and tegula dark brown. Foreleg dark brown, coxa, femur and tibia mixed with yellowish white; midleg dark brown, femur yellowish white mixed with dark brown distally, tarsus yellowish white at apex of each tarsomere; hindleg yellowish white ventrally, femur dark brown dorsally except yellowish white mixed with dark brown distally, tibia mixed with sparse dark brown dorsally, basal tarsomere of tarsus mixed with sparse dark brown on outside, rest of tarsomeres dark brown on outside except yellowish white at apices.
Forewing ground colour dark brown, with black, yellow, white and reddish brown scales; costal margin black, interrupted by irregular yellow spots; small black dot near base below costal margin, edged with a few reddish brown scales; cell with a black spot at middle, oblique, edged with a few reddish brown scales; white centered spot placed on outer margin of cell, surrounded by black and a few reddish brown scales; fringe concolourous with forewing. Hindwing dark brown, paler basally; fringe dark brown.
Male genitalia ( Fig. 25 View FIGURES 24‒29 ). Uncus not obviously produced. Socii semicircular, widened distally, setose. Gnathos elongate fusiform, with fine spines. Valva wide at base, gradually narrowed to apex; ventral margin concave below cuiller, obliquely straight distally. Transtilla a narrow band; transtilla lobes irregular, membranous, setose. Sacculus reaching before 1/3 length of valva; cuiller spoon-shaped, curved outward, with dense small spines distally, apically reaching anterior 1/3 from costa ( Fig. 25a View FIGURES 24‒29 ). Juxta heart-shaped; lateral lobes dilated and setose distally, exceeding posterior margin of juxta apically. Phallus curved medially; cornuti being numerous tiny spinules.
