A new Aphyosemion species from the Djoué River (Congo River Basin), Republic of the Congo (Teleostei: Cyprinodontiformes: Nothobranchiidae), with remarks on the type locality of Aphyosemion congicum (Ahl, 1924).

Abstract: Aphyosemion fellmanni, new species, is described from specimens collected at two locations in the Djoué River basin, northwest of Brazzaville (Republic of the Congo), based on its unique colour pattern of very wide black margins of dorsal, caudal, and anal fins in combination with inter-radial red stripes ("flames") in the caudal fin of male. Within the genus Aphyosemion sensu stricto it shares black fin margins with A. rectogoense (south-east Gabon) and A. congicum (central Democratic Republic of the Congo). Preliminary genetic data do not suggest a closer relationship with any of these two species. Due to the geographically close occurrence of Aphyosemion fellmanni, new species, to A. congicum with which it shares the wide black fin margins we studied literature to get more information on origin of the types of the latter. The type locality of the latter species was indicated as "Congo", collected by Büttner. Based on a publication on the German Congo Expedition (1884-1886) the type locality could be restricted to the area of the expedition route and most probably to the lower Kwango (Cuango) River.
