Diagnosis. Alcis maculata is very similar to Alcis micromaculata ( Sato, 2005: figs 27-29, 52, 62). Compared to A. micromaculata , A. maculata is larger, and less tinged with yellow, the transverse lines on the hind wing are narrower, and the discal spot is further from medial line. In the male genitalia, A. maculata has narrower cucullus, longer and slenderer paired processes of juxta. In the female genitalia, the lamella antevaginalis is narrower posteriorly than in A. micromaculata , and the colliculum is more strongly sclerotized laterally (modified based on the text and figures in Sato, 2005)

Distribution. China ( Sichuan, Xizang, Taiwan), India, Nepal, Thailand, Indonesia.
