(Figs. 1, 6)

Type material. Holotype: 3, China: Li-kiang, North Yunnan Province, 10.vii.1934, leg. H. Höne, genitalia slide No. 43. Paratypes: 4 3, same locality except dated 10–18.vii.1934, leg. H. Höne. Holotype and 3 paratypes are deposited at the Alexander Koenig Research Museum in Bonn ( Germany); 1 paratype in the Zoological Institute of the Russian Academy of Sciences in St.Petersburg, Russia.

Diagnosis. This species differs from the other members of the group by the oblong shape of the saccus and the slightly curved aedeagus with a small plate on the dorsal surface near the base in the male genitalia. In superficial appearance it is closely related to A. ventrangulata , differing in the pale colour of the thorax, the middle segment of the labial palpus white with fuscous colour only at base, the black spot at the base of the forewing small and narrow, and the light colouration of the hindwing.

Description. Adult (Fig. 1): Forewing span 20–22 mm. Head white, sometimes with brownish tint, with 2 small fuscous spots on frons. Basal half of antenna dark brown, apical half light brown. Labial palpus upcurved with appressed scales; middle segment white with fuscous scales at base; apical segment white with fuscous scales at apical part. Thorax usually white with small admixture of fuscous scales, rarely brown. Ground colour of forewing white, tinged with yellowish brown; discal point white with fuscous thin border, large fuscous triangular patch mixed with light scales situated above discal point; black point in middle of cell; narrow fuscous spot near base of forewing; some fuscous points along costal margin and termen; cilia light. Hindwing whitish with small yellow tint.

Male genitalia (Fig. 6): Socii rather large, rounded, with dense setae. Gnathos nearly rounded. Valva broad at base, tapered to rounded apex; ventral margin forming an angle at middle. Cuiller narrow, reaching upper margin of valva. Saccus oblong. Aedeagus 3 times longer than cuiller, slightly curved, with numerous tiny cornuti, and with small plate on dorsal surface near base.

Female: Unknown.

Distribution. China: Yunnan (Li-kiang).
