ABSTRACT

A new nematode genus and species. Neoparaseuratum travassosi n. g., n. sp., is described from the intestine of the freshwater thorny catfish, Pterodoras granulosus (Valenciennes), from the Paraná River, Brazil. This seuratoid nematode species represents a new genus of the family Quimperiidae, being characterized mainly by the presence of numerous narrow longitudinal bands of inflated cuticle extending along the cephalic region of the body, small deirids, postoesophageal position of the excretory pore, relatively short (0.159-0.303 mm), equal spicules and a gubernaculum, the absence of caudal alae and preanal sucker in the male, and by some other features.

Key words: Neoparaseuratum travassoni n. g., n. sp.; Nematoda; Quimperiidae; Pterodoras granulosus
