Résumé

This is a detailed biometric study of 88 Marcusenius specimens (Mormyridae) originating from the Ntem River Basin in southern Cameroon and the Ivindo River in Gabon (West Central Africa) including the type material of M. ntemensis and M. conicephalus. It demonstrates that both nominal species are synonymous. A study of the electric organ and the electric organ discharge of specimens originating from both systems confirmed this. Due to nomenclatorial priority M. ntemensis is considered as the senior synonym.
