eudoxus differs from the Charaxes druceanus in having the median band on the upperside of the forewing completely bordered on both sides by the deep black-brown ground-colour and towards the costal margin much narrowed but almost straight.
(1991)[5][6] Historical attempts to assemble a cluster of presumably related species into a "Charaxes jasius Group" have not been wholly convincing.
More recent taxonomic revision,[17] 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,[18] 26 are now considered together as The jasius Group.
[17] 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,[18] and are considered as the jasius subgroup.
