Abstract
Intraspecific morphological variation in Neolamprologus niger from seven localities along the north-western shoreline of Lake Tanganyika (Luhanga, Bemba, Ubwari West, Ubwari East, Yungu, Kabimba and Kalemie) was investigated. As a result of geographical variation, the populations could be categorized into a northern, a central and a southern group. A clear clinal pattern was found for several meristics and measurements. The lack of knowledge on the geographical variation in African cichlids and its implication for further taxonomic research is discussed.References
