The Cichlid Fishes of Lake Malawi, Africa

Abstract of Publication

Marsh, A.C. 1983. A taxonomic study of the fish genus Petrotilapia (Pisces: Cichlidae) from Lake Malawi. Ichthyological Bulletin of the J.L.B. Smith Institute of Ichthyology, Number 48: 1-14.  

The type-species of the cichlid fish genus Petrotilapia Trewavas 1935, P. tridentiger, is redescribed and two new species, P. genalutea and P. nigra, are described. These three species occur sympatrically at Monkey Bay. Morphological differences between the three species are slight and of little diagnostic value. Live coloration is the most important taxonomic character and can be used reliably to identify adults of the three species. Field observations of live fishes are shown to be of paramount importance in taxonomic studies of the genus Petrotilapia.
