| Abstract: | A new anisakid nematode, Raphidascaroides brasiliensis n. sp., is described from the intestine of the freshwater thorny catfish Pterodoras granulosus (Valenciennes) (Doradidae, Siluriformes) from Amazonia (Manaus), Brazil. It is characterised mainly by the smooth, almost rounded tail tip in both sexes, the length of the spicules (0.952–1.183 mm) and by the number and arrangement of the caudal papillae (24–34 pre-anal, 1 adanal and 5 postanal pairs and 1 median pre-anal papilla) in the male. It is the first Raphidascaroides species described from South America and the second species of this genus reported from a freshwater fish. |
