Diagnosis. The A. hyalina species-group is characterized by the combination of the following characters: 1) forewing base orange or ochreous, usually with one diffused transverse band at discal area, extending from the costa through the discal cell and reaching the dorsum, 2) 8 th tergite with its posterior part bifurcate (except for A. formosana ), 3) uncus broad and triangular and 4) posterior tegumenal projection narrow and rod-like, smooth on the surface.

External morphology of adult. Forewing length approximately 17–28 mm in males and 17.5– 30 mm in females. Antennae bipectinate with longer rami in males and shorter ones in females. Head, thorax and abdomen thinly-scaled. Both wings thinly-scaled and translucent. Ground color of forewing varying from creamy white to yellow with orange-marked forewing base and one transverse band in the medial zone, usually diffused. Veins darkened. Ground color of hindwing creamy white or greyish white. Veins sometimes darkened.

Male genitalia. Uncus broad at base and gradually narrowed towards tip with distal end rounded. Tegumen broad with rounded margins. Posterior tegumenal projection rod-like, narrow and smooth on the surface. Vinculum narrow. Saccus rounded, U-shaped. Juxta U-shaped. Valvae relatively broad and short, strongly sclerotized; distal end usually plate-like, covered by spinules, and sometimes developed into a projection, smooth or spiny. Aedeagus simple and slender.

Female genitalia. Similar to those of the A. pica species-group described above.

Distribution. Northwestern Himalaya through Western, Southern and Eastern China to Northern Indochina and Taiwan island ( Fig. 68 ).
