Based on the examination of 234 specimens of the Brazilian flathead, Percophis brasiliensis (Percophidae), caught in the Argentinean and Uruguayan Seas, the list of digenean species parasitizing P. brasiliensis is increased from 6 to 9, including the specific identification of two species previously reported at the generic level. The three news digenean records for P. brasiliensis are: Elytrophalloides oatesi, Parahemiurus merus and Aponurus laguncula, while that Ectenurus virgulus and Lecithocladium cristatum were identified to specific level. These reports showed the highest diversity of digeneans registered in fishes from the study region. The diversity of the digenean fauna of P. brasiliensis could be a consequence of the generalist food habits of this fish.
