Two new species of amphistome (Trematoda) are discribed from "pacu", Myleus ternetzi, from French Guiana. For one of these, a new genus is proposed. Additionally, a common species, Pseudocladorchis cylindricus, is reported. Pacudistoma guianensis sp. nov. is a robust form with a massive pharynx ; a large genital sucker ; long, convoluted ceca ; and a subterminal acetabulum that is smaller than the genital sucker. Myleustrema concavatum gen. et sp. nov., on the other hand, has a slender, flattened body, concave dorsally ; a small pharynx ; no genital sucker ; ceca that are short, slender, and nearly straight ; and a small, terminal acetabulum which is provided with papillae. The two new forms seem to be highly host specific and could therefore be used as biological markers. (Résumé d'auteur)
