( Figs 6 View FIGURES 5–10 , 12 View FIGURES 11–15 , 17 View FIGURES 16–19 )
Type material. Holotype ♂, CHINA, Ningxia: Shapotou, Zhongwei , 1245 m, 13.VII.2024, leg. ZW Han & SY Tang, gen. slide No. GLZ24360.
Paratypes: CHINA, Ningxia: 6♀, Shapotou, Zhongwei , 1170−1644 m, 27−28.VI.2021, 25.VII.2023, 11−13. VII.2024, leg. H Sun & ZL Tao, HH Li, H Sun & ZW Han, ZW Han & SY Tang, gen. slide Nos. GLZ24288, GLZ24203, GLZ24359, GLZ25215, GLZ25216 .
Diagnosis. The new species is similar to A. plumbatella ( Ragonot, 1888) , but differs from the latter externally by the long (3 times as long as an eye diameter) porrect, weakly up-turned labial palpus and the forewing without costal band. In A. plumbatella , the labial palpus is short (equal to an eye diameter), porrect or up-turned, and the forewing has a white costal band mixed with some brown. The male genitalia of the new species are characterized by the uncus obtusely rounded at apex, the valva narrowed at the apical 1/4 and the aedeagus narrowed medially. In A. plumbatella , the uncus is pointed at apex, the valva is parallel sided at apical 1/4 and the aedeagus is narrowed distally. The female genitalia of the new species can be recognized by the subovate corpus bursae with several cone-shaped spines gathered in the posterior portion. The female genitalia of A. plumbatella differ in the elliptical corpus bursae with cone-shaped spines gathered in the medial portion.
Description. Adult ( Fig. 6 View FIGURES 5–10 ). Wingspan 22.0−26.0 mm.
Head. Vertex white mixed more or less with brown; antenna with scape light brown, twice as long as wide; flagellum with flagellomeres brown basally and white apically on dorsal surface, with white short cilia on ventral surface. Labial palpus white on inner surface, segment I white, segment II and segment III dark brown mixed with white on outer surface, segment III 4 times as long as segment II, protrude forward.
Thorax. Mesonotum, patagia, tegulae yellow mixed with white and dark brown. Forewing colored with alternating brown, yellow and white; antemedial line white, tilted inward, edged with yellow and dark brown streaks on inner side; postmedial line white, tilted outward, edged with yellow and dark brown streaks on outer side, area between antemedial and postmedial lines dark brown except two yellow longitudinal lines; two discocellular spots black, separated; terminal line dark brown, fringe white basally brown distally. Hindwing light brown, terminal line dark brown, fringe white. Legs with coxa, femur, tibia white mixed some dark brown, tarsus brown mixed some white.
Abdomen. Brown and with long white scales at apex of each segment.
Male genitalia ( Fig. 12 View FIGURES 11–15 ). Uncus triangular, twice as long as wide, apex wide, blunt rounded. Gnathos clavate, about 1/2 length of uncus, apex slightly curved. Transtilla long, triangular. Valva relatively broad, subparallel sided, 3.5 times as long as wide, apex rounded; costa arch-shaped, wide medially, narrowed distally, reaching tip of costal margin of valva; sacculus wide basally, narrowed distally, about 2/3 length of valva. Juxta U-shaped, twice as long as wide. Vinculum nearly V-shaped, anterior margin short, straight. Aedeagus slender, narrowed medially and weakly widened at both apexes.
Female genitalia ( Fig. 17 View FIGURES 16–19 ). Papillae anales triangular, with elongate setae.Anteriores and posteriores apophyses clavate and nearly equal in length. Eighth tergum quadrate, width equal to length, anterior margin convex and arched, posterior margin straight with elongate setae. Antrum small and funnel-shaped. Ductus bursae narrow, with anterior 1/4 weakly widened and with many spines in transition zone to corpus bursae. Corpus bursae subovate, with several cone-shaped spines in posterior part.
Distribution. China ( Ningxia).
Etymology. The new species is named after Professor Bong-Kyu Byun (Hannan University, Korea) in recognition of his contributions over the years to the taxonomy of Lepidoptera and the development of the journal Zootaxa .
