KNOFF, Marcelo; SAO CLEMENTE, Sérgio Carmona de; PINTO, Roberto Magalhães  and  GOMES, Delir Corrêa. Nematodes of elasmobranch fishes from the southern coast of Brazil. Mem. Inst. Oswaldo Cruz [online]. 2001, vol.96, n.1, pp.81-87. ISSN 0074-0276.

New records for nematode species recovered from elasmobranch fishes in Brazil are established and new systematical arrangements proposed. Parascarophis sphyrnae Campana-Rouget, 1955 from the spiral valve of Sphyrna zygaena is referred for the first time in South America as a new host record. Procamallanus (S.) pereirai Annereaux, 1946, from the spiral valve of Raja castelnaui is reported parasitizing an elasmobranch host. Nematode larvae of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are listed from the stomach and spiral valves of several hosts. Anisakidae larvae previously referred in Brazil in the genus Phocanema should be reallocated in Pseudoterranova. Nematodes of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are reported for the first time parasitizing elasmobranchs in Brazil.

Keywords : Nematoda; new records; elasmobranch fishes; Brazil.
