在巴西的板鳃类鱼类线虫物种的新记录，并提出了新的系统安排。在南美洲首次报道了一种新的寄主记录，即来自双叶副蛔虫Parascarophis sphyrrhizCampana-Rouget，1955。Procamallanus（S.）pereirai Annereaux，1946年，从螺旋瓣的拉贾castelnaui报道寄生板鳃类主机。异尖线虫属（Anisakis）、对盲线虫属（Contracaecum）、拟尖线虫属（Pseudoacidova）和针蛔虫属（Raphidascaris）的线虫幼虫被列入几种宿主的胃和螺旋瓣中。以前在巴西提到的异尖线虫属的幼虫应重新分配在Pseudoacrylova。异尖线虫属、对盲线虫属、拟尖线虫属和针蛔虫属的线虫在巴西首次寄生于板鳃类。
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.
