Charaxes antiquus

Historical attempts to assemble a cluster of presumably related species into a "Charaxes jasius Group" have not been wholly convincing.

More recent taxonomic revision,[4] 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,[5] 26 are now considered together as The jasius Group.

[4] 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,[5] and are considered as the jasius subgroup.

[4] Further exploration of the phylogenetic relationships amongst existing Charaxes taxa is required to improve clarity.
