Type material. CHINA, Tibet: Holotype ♂, Bomi County (29.85ºN, 95.76ºE), 2800 m, 19.VIII.2003, leg. XP Wang & HJ Xue, slide No. WYQ16570 . Paratypes: 2♂, Sangdeng Village , Bomi County, 2695 m, 10.VIII.2018, leg. MJ Qi, slide Nos. TZL19375, TZL20328 ; 8♂ 6♀, Guxiang , Bomi County, 2623 m, 30.VI.2019, leg. MJ Qi & JQ Deng, slide Nos. TZL19454 ♂, TZL19453 ♂, TZL19473 ♂, TZL19280 ♂, TZL20318 ♀, TZL20314 ♀.

Diagnosis. The new species can be distinguished from its congeners by the sacculus having a free sub-rectangular process. It is similar to A. apicilata sp. nov. in male genitalia, and the differences between them are stated under A. apicilata .

Description. Adult ( Fig. 7 ). Forewing length 7.0– 7.5 mm.

Head yellowish brown. Antenna: scape brown on dorsal surface, pale yellow on ventral surface; flagellum yellow, with brown annulations on dorsal surface. Labial palpus pale yellow, second palpomere brown on outer surface, third palpomere with a longitudinal brown line on ventral surface.

Thorax and tegula brown. Forewing ground color pale yellow, densely with brown scales; discal, discocellular and plical spots black, discocellular spot largest; tornal spot dark brown, elongate; fringe pale yellow, greyish brown at tip. Hindwing and fringe yellowish brown. Fore- and midlegs yellow on ventral surface, black on dorsal surface, yellow at apex of each tarsomere; hindleg yellow, with sparse brown scales.

Male genitalia ( Fig. 21 ). Uncus broad at base, slightly narrowed to middle, distal half slender, clavate. Gnathos with mesial plate small, hooked, pointed at apex; basal arms narrowly banded, about five times of mesial plate. Tegumen narrowed medially, with a V-shaped anterior emargination at middle; lateral arm sub-fusiform, narrowed distally. Valva narrow at base, slightly widened to basal 2/5, distal 3/5 almost evenly wide, broadly rounded at apex; costal margin shallowly concave before middle, arched medially; sacculus wide at base, narrowed to basal 1/5 length of valva, with a heavily sclerotized sub-rectangular process near its dorsal margin. Saccus sub-rectangular, very short, width twice of length. Juxta weakly sclerotized, sub-rectangualr. Aedeagus about 1/2 length of valva, tubular, slightly tapered to apex; cornuti consisting of a cluster of spines ( Fig. 21a ).

Female genitalia ( Fig. 32 ). Apophyses posteriores about 1.5 times length of apophyses anteriores. Eighth tergum nearly straight on posterior margin, eighth sternum with a cut at middle on posterior margin. Antrum weakly sclerotized, parallel sided laterally. Ductus bursae thickened and weakly sclerotized posteriorly, thinner and membranous anteriorly. Corpus bursae ovoid, about same length of ductus bursae; signum below entrance of corpus bursae, semicircular, with several denticles ( Fig. 32a ).

Distribution. China (Tibet).

Etymology. The specific epithet of the new species is from the type locality, Bomi.
