The Cichlid Fishes of Lake Malawi, Africa

Abstract of Publication

Twentyman-Jones, V., A.J. Ribbink, and D. Voorvelt. 1997. Colour clues to incipient speciation of Pseudocrenilabrus philander (Teleostei, Cichlidae). South African Journal of Science 93 (11-12): 529-537.  

Colour variation which distinguishes between allopatric populations of Pseudocrenilabrus philander is described here as a basis for, and to stimulate, further work on morphology, genetics, ecology, zoogeography and behaviour: Collectively, these studies should ultimately lead to confident categorisations of the Pseudocrenilabrus taxa and to an improved understanding of cichlid evolution. At present there are clear indications of differentiation, suggesting that incipient speciation is in progress and that some taxa might be considered to be distinct species.
