Stefano Valdesalici and Wolfgang Eberl: Aphyosemion bitteri (Cyprinodontiformes: Nothobranchiidae), a new killifish species from the northern Massif du Chaillu, Gabon, pp. 61-68

Abstract
A new Aphyosemion species is described from Gabon, based on eight specimens collected in a small stream within the hydrographic system of the Ikoy River on the northwestern edge of the Massif du Chaillu. Aphyosemion bitteri, new species, can be distinguished from all species of the genus by its maze-like red pattern on the caudal fin. It belongs to the A. grelli species group (Valdesalici & Eberl 2014) by sharing with A. grelli and A. mengilai the yellow basal two thirds and the greyish marginal third on the unpaired fins of females, but it can be easily distinguished from these two species by differing male coloration and meristics.
