Diagnosis. The new species is similar to A. fallaciosa Wang, 2004 in male genitalia. It can be distinguished by the costa with a process at base and the valva not produced ventrally. In A. fallaciosa , the costa lacks a process at base and the valva is roundly produced at distal 5/7 ventrally. It is also similar to A. trapeziformis sp. nov., and the differences between them are stated under A. trapeziformis .

Description. Adult ( Fig. 10 View FIGURES 9–16 ). Forewing length 4.6−5.6 mm.

Head with frons brown, vertex pale yellow. Antenna pale yellow on ventral surface; scape yellowish brown, flagellum ringed with brown on dorsal surface. Labial palpus with second palpomere yellow on inner surface, dark brown on outer surface, pale yellow at apex; third palpomere yellow, with scattered brown scales in distal 1/3.

Thorax and tegula yellow mixed with brown. Forewing ground color yellow, with yellowish brown scales; costal margin with a black spot at base; with black spot near base of subcostal vein and dorsum; discal and plical spots rounded, black; discocellular and tornal spots black, weakly touching each other, forming a rectangular speckle; terminal dots black, ranging from distal 1/3 of costal margin along termen to tornus; fringe brown except yellowish brown at apex. Hindwing and fringe brown. Fore- and midlegs yellowish brown on ventral surface, black on dorsal surface, yellow at apex of each tarsomere; hindleg pale yellow, tarsus with brown scales.

Male genitalia ( Fig. 24 View FIGURES 23–28 ). Uncus clavate, slender, rounded at apex. Gnathos circular, uniform in width. Tegumen widened medially, arched on posterior margin, with a large anterior emargination; lateral arm banded, almost uniform. Valva elongate sub-rectangular, indistinctly narrowed distally, rounded at apex; costa slightly concave at basal 1/3, with an inverted triangular process at base directed downward. Sacculus sub-trapezoidal, dorsal margin reaching below costa; ventral margin narrowly banded, with a free spine-shaped distal process reaching apex of valva. Saccus wide at base, narrowed to pointed apex. Juxta rectangular on ventral surface, slightly concave in V shape at middle on posterior margin; dorsal surface turriform, with coiled ridges. Aedeagus about 5/6 length of valva, tubular, slightly tapered distally, truncate apically; cornuti being a bunch of spines ( Fig. 24a View FIGURES 23–28 ).

Female genitalia ( Fig. 35 View FIGURES 34–39 ). Apophyses posteriores about twice length of apophyses anteriores. Eighth tergum concave on posterior margin, eighth sternum convex and incised at middle on posterior margin, setose. Antrum concave in V shape at middle on posterior margin. Ductus bursae with posterior half sclerotized, anterior half membranous; ductus seminalis from anterior 2/5 of ductus bursae. Corpus bursae slightly longer than ductus bursae, rounded; two signa sub-ovoid, with small teeth, with unequally sized spinules radiating from all margins, smaller signum below entrance of corpus bursae ( Fig. 35a View FIGURES 34–39 ), larger signum situated at posterior 1/4.

Distrubition. China (Guangxi, Guizhou, Hainan, Yunan) .

Etymology. The specific epithet of the new species is derived from the Latin basi- and processus, referring to the basal process of the costa.
