Charaxes junius is distinguished from brutus by having the discal band on the upper surface light yellow and in cellule 1 b of the forewing 6–1 mm. in breadth. Abyssinia. - — somalicus Rothsch. only differs from junius in the somewhat narrower median band on both wings. Somaliland.[4]
Subspecies
Charaxes junius junius (western and south-western Ethiopia)
Charaxes junius Oberthür, 1880 is treated as a subspecies of brutus (Cramer, 1779) by Van Someren [6] Henning treats junius as a distinct species on the authority of Plantrou (1983).[7][8]
Related species
Historical attempts to assemble a cluster of presumably related species into a "Charaxes jasius Group" have not been wholly convincing. More recent taxonomic revision,[9] corroborated by phylogenetic research, allow a more rational grouping congruent with cladistic relationships. Within a well-populated clade of 27 related species sharing a common ancestor approximately 16 mya during the Miocene,[10] 26 are now considered together as The jasius Group.[9] One of the two lineages within this clade forms a robust monophyletic group of seven species sharing a common ancestor approximately 2-3 mya, i.e. during the Pliocene,[10] and are considered as the jasius subgroup.[9] The second lineage leads to 19 other species within the Jasius group, which are split into three well-populated subgroups of closely related species.
