Stefano Valdesalici and Wolfgang Eberl: Aphyosemion jeanhuberi, a new killifish species of the Aphyosemion ogoense species group (Cyprinodontiformes: Nothobranchiidae), with remarks on the identity of Aphyosemion louessense (Pellegrin, 931), pp. 110-119
Aphyosemion jeanhuberi, new species, is described from the border area between Gabon and Congo (Brazzaville) in the Massif du Chaillu. It can be distinguished from the remaining members of the Aphyosemion ogoense species group by a unique colouration of males. Despite obvious differences and its geographically isolated distribution range, specimens of this species have been hitherto erroneously considered as belonging to Aphyosemion louessense; remarks on the latter species based on recent collections are given together with an identification key for the species of the Aphyosemion ogoense species group.
