New records for helminth species recovered from elasmobranch fishes in Brazil are established. Digenean and acanthocephalan parasites of elasmobranch fishes are reported from the southern coast of Brazil: Otodistomum veliporum (Creplin, 1837) Stafford, 1904 (Digenea: Azygiidae) in the stomach and spiral valve of Dipturus trachydermus and in the spiral valve of Squatina sp. Cystacanths and juveniles of the acanthocephalans Corynosoma australe Johnston, 1937 and Corynosoma sp., in the spiral valve of Squatina sp., Galeorhinus galeus and Hexanchus griseus and in the stomach of Squalus megalops; a juvenile of Gorgorhynchus sp., in the spiral valve of Sphyrna zygaena. Dipturus trachydermus and Squatina sp. are new host records for O. veliporum. Digeneans and acanthocephalans are reported for the first time parasitizing elasmobranch fishes in Brazil.
建立了从巴西软骨鱼类中发现的蠕虫物种新记录。报告了巴西南部海岸软骨鱼类的复殖吸虫和棘头虫寄生虫：在糙皮鳐的胃和螺旋瓣以及琵琶鲛属的螺旋瓣中发现了绒毛耳吸虫（Otodistomum veliporum，克里普林，1837年；斯塔福德，1904年）（复殖目：阿齐吉科）。在琵琶鲛属、加氏真鲨和灰六鳃鲨的螺旋瓣以及大眼角鲨的胃中发现了南方冠棘头虫（Corynosoma australe，约翰斯顿，1937年）和冠棘头虫属的棘头体和幼虫；在双髻鲨的螺旋瓣中发现了戈氏棘头虫属的幼虫。糙皮鳐和琵琶鲛属是绒毛耳吸虫的新宿主记录。首次报告了复殖吸虫和棘头虫寄生在巴西的软骨鱼类中。
