Abstract

A new nematode species, Capillostrongyloides arapaimae check for this species in other resources sp. n., is described from the intestine and pyloric caeca of the arapaima, Arapaima gigas check for this species in other resources (Schinz), from the Mexiana Island, Amazon river delta, Brazil. It is characterized mainly by the length of the spicule (779-1,800 µm), the large size of the body (males and gravid females 9.39-21.25 and 13.54-27.70 mm long, respectively) and by the markedly broad caudal lateral lobes in the male. It is the third species of genus Capillostrongyloides reported to parasitize Neotropical freshwater fishes.
