" Pelmatochromis nigrofasciatus Pellegrin is not, as has been suggested, a synonym of P. ocellifer Boulenger. The two species are defined and their relationships are discussed. The name Pelmatochromis exsul Trewavas was based on a misidentification of young Hemichromis bimaculatus Gill. Recognition of this fact removes the only record of Pelmatochromis from East Africa. A new genus is proposed for P. congicus Boulenger and a key to the species of Pelmatochromis is given. Reasons are given for excluding Pelmatochromis from Tilapia and retaining T. busumana in Tilapia. Sarotherodon Rüppell is considered to require full generic rank and Tilapia and Sarotherodon are defined. "
