Notes

The population from S.E. Thailand and Cambodia is thought to be this taxon. However, it has a slightly broader black marginal border on the upperside of both wings than the nominotypical subspecies. Further taxonomic and distributional studies are needed.

Identification of the Arhopala alea subgroup within the Arhopala cleander group is extremely difficult, even by examination of specimens. It is essential to identify both the upper and under surfaces of the wings from the specimen. Although there are many field photos, most are either misidentified or unidentifiable and therefore cannot be used as records. A review of all species in this group by molecular analysis is required.
