Abstract
A new anisakid nematode, Raphidascavoides brasiliensis n. sp., is desc ribed from the intestine of the freshwater thorny catfish Pterodoras g ranulosus (Valenciennes) (Doradidae, Siluriformes) from Amazonia (Mana us), 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) an d 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 Am erica and the second species of this genus reported from a freshwater fish.
