Endonuclease Analysis

Relationships among the seven recognized subspecies of the widespread African cichlid Oreochromis niloticus (L.) were investigated using restriction endonuclease analysis of mitochondrial DNA. Changes in nomenclature are based on estimates of sequence divergence and concordant results from phenetic, cladistic, and maximum likelihood analyses of molecular character sets. Oreochromis niloticus cancellatus and O. n. filoa are reassigned to O. cancellatus as O. c. cancellatus and O. c. filoa, respectively. The tilapiine fishes of Lake Tana, Ethiopia, previously assigned to O. n. cancellatus, are here described as Oreochromis niloticus tana subsp.nov. in recognition of their distinctive molecular phenotypes.
