Striped seabream, Lithognathus mormyrus, caught on the Tunisian coasts carried two species of parasitic copepods belonging to the family Lernaeopodidae Olsson, 1869 (Siphonostomatoida Thorell, 1859). One was at first identified as Sparidicola papilliferens Kabata & Tareen, 1987. The study of a paratype from another species of the same genus, S. lithognathi (Kensley & Grindley, 1973) (= Brachiella lithognathae Kensley & Grindley, 1973) collected on South Africa’s striped sea bream (Lithognathus lithognathus [Cuvier, 1830]), led us to the conclusion that Sparidicola papilliferens and S. lithognathi belong to the same species that must be consequently named S. lithognathi. The second one is a species new to science, Clavellotis briani n. sp. It was observed for the first time by Brian (1924), on striped seabream of the Mauritanian coasts, but he did not name it. Sparidicola lithognathi and Clavellotis briani n. sp. have been also collected on striped seabream on the French Mediterranean coast (Gulf of Lions), in Kenitra area (Morocco) and in Dakar area (Senegal).
