The present study redescribes the monotypic genus Afrodiplozoon Khotenovski, 1981, a diplozooid parasite endemic to Africa, based on material collected during surveys carried out in the Limpopo Province, South Africa, from two cyprinid hosts Labeobarbus marequensis and Enteromius paludinosus. Morphometrical analysis of the composition of internal organs and attachment clamps, using light microscopy and scanning electron microscopy, provided details for the genus and species redescriptions. Posterior attachment apparatus can bear up the 15 pairs of the clamps with the first pair of clamps distinctly smaller and not fully developed. Molecular characterization of the second internal transcribed spacer (ITS2) rDNA and phylogenetic analysis revealed the position of Afrodiplozoon polycotyleus as a sister taxon to Paradiplozoon krugerense and Paradiplozoon bingolenisis, distant from other African representatives of the genus Paradiplozoon, Paradiplozoon vaaleense and Paradiplozoon ichtyoxanthon
