Three new species of  Synodontella  Dossou & Euzet, 1993 are described from two species of  Synodontis  (Mochokidae) collected from the middle course of the Boumba River (East Cameroon):  Synodontella angustupenis  n. sp. from  Synodontis nummifer ,  Synodontella longipenis  n. sp. and  Synodontella simplex  n. sp. from  Synodontis decorus . These new species are different from the other  Synodontella  species already described due to their horseshoe-shaped dorsal transverse bars.  Synodontella angustupenis  differs from  S. longipenis  and  S. simplex  by the morphology of its penis, a thin tube, and its accessory piece, bifid at its extremity.  Synodontella longipenis  differs from the other two species by the morphology and the size of its male copulatory organ, which is very long.  Synodontella simplex  differs from  S. angustupenis  and  S. longipenis  by the shape of its penis, which is simple, and of its accessory piece, with a developed heel. The difference between the dorsal transverse bars of  Synodontella  species from the Sanaga River in Cameroon (and other localities in Africa), slightly curved, and those from the Boumba River, horseshoe-shaped, makes it possible to separate  Synodontella  species into two different subgroups. This difference can be explained by a long isolation period of the hosts, living in different river basins, followed by the divergence of the parasite populations (vicariant speciation).
