A survey of bothriocephalidean tapeworms (Cestoda) parasitizing African freshwater fish is provided. Based on critical evaluation of type specimens and extensive, newly collected material, only the following seven species, instead of 19 taxa listed in the literature, are considered to be valid and their redescriptions are provided: Bothriocephalus acheilognathi Yamaguti, 1934; Bothriocephalus claviceps (Goeze, 1782); Ichthybothrium ichthybori Khalil, 1971; Kirstenella gordoni (Woodland, 1937) n. comb.; Polyonchobothrium polypteri (Leydig, 1853); and Tetracampos ciliotheca Wedl, 1861. In addition, Tetracampos martinae Kuchta n. sp. is proposed for tapeworms from the catfish Bagrus meridionalis from Lake Malawi. The new species differs from T. ciliotheca in a much larger body (19 cm versus 3 cm), dorsoventally flattened strobila and numerous (39 versus 25–35) and longer apical hooks (up to 98 μm versus less than 50 μm). Kirstenella Kuchta n. gen. is proposed to accommodate Senga gordoni Woodland, 1937 as its type species. The new genus is distinguished from other genera of the Bothriocephalidae by the presence of an apical disc armed with two lateral semicircles of large hooks, cortical vitelline follicles and large-sized cirrus-sac. All but one valid species were recollected. Bothriocephalidean cestodes are widely distributed throughout Africa, but only two species, B. acheilognathi and T. ciliotheca, occur in other continents. All but one species (B. acheilognathi) exhibit narrow host specificity, being limited either to one host species (K. gordoni in Heterobranchus bidorsalis and T. martinae in Bagrus meridionalis) or one host genus (I. ichthybori in Ichthyborus spp., P. polypteri in Polypterus spp. and T. ciliotheca in Clarias spp.). Molecular data based on partial sequences of the large subunit rDNA (lsrDNA) show monophyletic position of all African taxa analysed (B. acheilognathi, I. ichthybori, K. gordoni, P. polypteri and T. ciliotheca).
