Description Gyrodactylus infecting catfishes from the African continent are reported, including new data from Sudan, Senegal, Kenya and Mozambique. Haptoral sclerite morphometry and nuclear ribosomal DNA sequences revealed the presence of eight Gyrodactylus species. On Senegalese Synodontis nigrita (Valenciennes), Gyrodactylus synodonti sp. n. and Gyrodactylus nigritae sp. n. are described. These are the first records of gyrodactylid parasites from mochokid hosts. From the fins of North African catfish, Clarias gariepinus (Burchell) collected in Mozambique, Gyrodactylus alekosi sp. n. and Gyrodactylus rysavyi Ergens, 1973 were identified. Gyrodactylus rysavyi was also identified from Kenyan C. gariepinus and Senegalese Clarias anguillaris (L.). From the fins of C. anguillaris studied in Senegal, two more species, Gyrodactylus transvaalensis Prudhoe et Hussey 1977 and Gyrodactylus gelnari sp. n. were recognised. In addition, Gyrodactylus turkanaensis sp. n. from the gills of Kenyan C. gariepinus was described and an undescribed Gyrodactylus sp. was recorded from Sudanese representatives of the same host. The study highlights the hitherto understudied diversity of viviparous monogenean parasites throughout the African continent.
