Eight species of Pandarus Leach, 1816 collected from hosts caught off South Africa are reported. These species include P. bicolor Leach, 1816, P. niger Kirtisinghe, 1950 and P. carcharhini Ho, 1963 belonging to the bicolor group and P. cranchii Leach, 1819, P. satyrus Dana, 1849, P. smithii Rathbun, 1886 and P. sinuatus Say, 1818 belonging to the cranchii group. Notes on previous and new distinguishing features are provided with illustrations, specifically the relative lengths of the dorsal plates and caudal rami as well as the structure of the distomedial spine on the second segment of leg 1 exopod. Additionally, illustrated re-descriptions are provided for P. satyrus and P. sinuatus. Furthermore, a new species Pandarus echinifer n. sp., also belonging to the cranchii group, collected from the snaggletooth shark Hemipristis elongata (Klunzinger) is described. This species is most similar to P. sinuatus but can be distinguished from it by the heavily spinulated distomedial spine on the last segment of the first leg exopod. Molecular analysis of the cytochrome oxidase I partial gene is used to calculate sequence divergences amongst different individuals and species. According to the results (as well as based on morphological characters) P. rhincodonicus Norman, Newbound & Knott, 2000 is a synonym of P. cranchii. New hosts and geographic localities from South Africa (and Ningaloo Park, Western Australia) are reported.
