Diagnosis. The new species is similar to A. bomiensis sp. nov. It can be distinguished in male genitalia by the saccullus having a sub-triangular process, the inverted trapezoidal juxta, and the saccus narrowed to rounded apex; in female genitalia, by the signum being an arched basal plate bearing two spines. In A. bomiensis, the process of the sacculus, the juxta and the saccus are all sub-rectangular; and the semicircular signum is denticulate and lacks spines.
Description. Adult (Fig. 6). Forewing length 6.5–6.9 mm.
Head creamy white, brown around eyes. Antenna: Scape dark brown; flagellum pale yellow alternated with brown. Labial palpus pale yellow, second palpomere brown on outer surface, third palpomere dark brown on ventral surface.
Thorax and tegula pale brown. Forewing ground color yellow, with scattered brown scales; costal margin with basal 1/5 dark brown; discal, discocellular and plical spots brown, ovoid; tornal spot dark brown, elongate; terminal dots brown, ranging from distal 1/3 of costal margin along termen to tornus; fringe yellow, brown medially. Hindwing and fringe yellowish brown. Fore- and midlegs pale yellow on ventral surface, dark brown on dorsal surface; hindleg yellow, tarsus pale brown on outer surface distally.
Male genitalia (Fig. 20). Uncus wide at base, slightly narrowed to rounded apex, convex mediolongitudinally. Gnathos with mesial plate short, triangular; lateral arms uniformly slender, about three times length of mesial plate. Tegumen inverted V-shaped, narrowed medially, with a semicircular anteromedial emargination. Valva with basal half sub-rectangular, slightly widened from midle to truncate apex; costal margin concave before middle, arched distally; ventral margin weakly arched, produced ventroapically; sacculus uniformly banded, about 1/5 length of ventral margin of valva, with a triangular process mediodorsally. Saccus about 3/5 length of uncus, broad at base, slightly narrowed to rounded apex. Juxta inverted trapezoidal. Aedeagus about 7/12 length of valva, with a tooth at apex dorsally, with a cluster granules distally; cornuti consisting of several spines at distal 1/5 (Fig. 20a).
Female genitalia (Fig. 31). Apophyses posteriores approximately 1.5 times length of apophyses anteriores. Eighth tergum slightly concave on posterior margin; eighth sternum arched, shallowly concave at middle on posterior margin. Lamella postvaginalis large, anterior margin slightly concave at middle; posterior margin deeply concave in broad V shape at middle, forming two triangular lateral lobes; lateral margin with a slender process extending downward and curved before middle.Antrum short, sclerotized posterolaterally. Ductus bursae uniformly wide, heavily sclerotized in about posterior 1/5, membranous in anterior 4/5. Corpus bursae rounded, about same length as ductus bursae; signum situated near entrance of corpus bursae, basal plate arched, with one long and one short spine extending from middle (Fig. 31a).
Distribution. China (Yunnan).
Etymology. The specific epithet of the new species is derived from the Latin apici- and latus, referring to the distally widened valva.
