The specialist synthesis distinguishes pyramus in Nepal, northeastern India and northwestern Thailand; kandha in southern India; and nominate acalis in northern Thailand, Laos and Cambodia. It records perakana in the Malay Peninsula and peninsular Thailand, inomatai in central and southern China, including Hong Kong, and shinkaii at Tam Dao in northern Vietnam. [3]

Daniel Chang photographed a living D. acalis inomatai in Hong Kong on 29 May 2009. [3]

The specialist Delias synthesis describes the dorsal hindwing character and regional forms. The Smithsonian record provides a pinned collection specimen, and the University of Florida catalogue records the species within Delias. [3][2][1]
