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 ). 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 ). 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 ).

Female genitalia ( Fig. 35 ). 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 ), 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.
