Description From 2004 to 2007 the parasitological survey of african freshwater fishes in National park Niokolo Koba Senegal (West Africa) were realized. Altogether 471 specimens of fishes from 20 families and of 55 species were investigated for the presence of parasites. Three genera of the viviparous gyrodactylids were collected from 12 fish species. Five species of the genus Macrogyrodactylus Malmberg 1957 were found on two host fishes Polypterus senegalus and Clarias anguillaris. This finding represents the first record of monogenean parasite of the genus Macrogyrodactylus in Senegal. Members of the genus Gyrodaclytus Nordmann 1832 were recorded from 11 host species and for seven of them represent new parasite records. From the gills of P. senegalus a new genus of viviparous monogenean was discovered. General anatomy of the parasite body is similar to the description of the genus Gyrodactylus but the morphology of the sclerites of the attachement apparratus is different.
