Charaxes hansali, the cream-banded charaxes, is a butterfly in the family Nymphalidae. It is found in Tanzania, Rwanda, Kenya, Uganda, Sudan, Ethiopia, Somalia, Saudi Arabia, Yemen and Oman.{{Cite web |url=http://atbutterflies.com/downloads/nymphalidae_charaxini.doc |title=Afrotropical Butterflies: File H - Charaxinae - Tribe Charaxini |access-date=2012-05-22 |archive-date=2013-11-09 |archive-url=https://web.archive.org/web/20131109071734/http://atbutterflies.com/downloads/nymphalidae_charaxini.doc |url-status=dead }}

Description

Ch. hansali Fldr. closely approaches Charaxes pelias in the markings, but has a broad light yellow discal band extending to the inner margin of the hindwing and the basal part of the upper surface is darker black-brown; the distal yellow spots in cellules 3—7 of the forewing are small and completely separated from the band; the yellow spots at the distal margin of the hindwing are streak-like and completely separated from the distal margin by the thick black marginal line; the tails are longer than in pelias ; the light-bordered spots in the basal part of the under surface have grey centres, as in pelias. Abyssinia and the adjacent parts of

Somaliland. — baringana Rothsch. only differs from the type-form in the narrower discal band of the upper surface and the free red-brown spots at the distal side of the median band on the hindwing beneath.

Biology

The habitat consists of arid savanna.

The larvae feed on Salvadora persica, Osyris lanceolata, Colpoon compressum;[http://www.nic.funet.fi/pub/sci/bio/life/insecta/lepidoptera/ditrysia/papilionoidea/nymphalidae/charaxinae/charaxes/index.html (Nigel Venters, at Markku Savela: Lepidoptera and some other life forms)] and Dobera glabra.Notes on the biology of hansali are provided by

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,{{Cite book|title=Butterflies of the World: Charaxes 1|last=Turlin|first=B.|publisher=Goecke & Evers|year=2005|isbn=3937783156|location=Keltern|pages=2–3|editor-last=Bauer & Frankenbach|volume=22}} 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, 26 are now considered together as The jasius Group. One of the two lineages forms a robust clade of seven species sharing a common ancestor approximately 2-3 mya, i.e. during the Pliocene,[http://www.nymphalidae.net/Aduse-Pokuetal2009.pdf/ "Out of Africa again: A phylogenetic hypothesis of the genus Charaxes (Lepidoptera: Nymphalidae) based on five gene regions"] {{Webarchive|url=https://web.archive.org/web/20190725181224/http://www.nymphalidae.net/Aduse-Pokuetal2009.pdf |date=2019-07-25 }}.

The jasius Group (26 Species)

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