Charaxes tectonis, the mountain silver-barred charaxes, is a butterfly in the family Nymphalidae. It is found in Nigeria and Cameroon.[3] The habitat consists of sub-montane and montane forests.

Historical attempts to assemble a cluster of presumably related species into a "Charaxes jasius Group" have not been wholly convincing. More recent taxonomic revision,[5] 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,[6] 26 are now considered together as The jasius Group.[5] 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,[6] and are considered as the jasius subgroup.[5] The second lineage leads to 19 other species within the Jasius group, which are split into three well-populated subgroups of closely related species.

The jasius Group (26 Species):[5]

Clade 1: jasius subgroup (7 species)

Clade 2: contains the well-populated three additional subgroups (19 species) of the jasius Group: called the brutus, pollux, and eudoxus subgroups.[5]

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