Probably close to A. nisus and associated species (see A. nisus). Races chionogaster, ventralis and erythronemius often treated as three separate species (e.g. originally in HBW) on basis of “morphology, ecology and probably behaviour”#R#R, but review of museum material indicates that distinctiveness of these taxa greatly reduced by considerable amount of variation within each#R#R, in addition to which there is evidence of gene flow between highly variable ventralis and nearest erythronemius#R. Described form A. salvini is pale morph of ventralis. Ten subspecies recognized.

Subspecies and Distribution
