Rhinebothrium paranaensis n. sp. (Tetraphyllidea: Cestoda) is described from the freshwater stingray Potamotrygon falkneri collected in the Colastiné River, a tributary to the Lower Parana River in Argentina. The specimens were studied in detail using light and scanning electron microscopy and histology. Rhinebothrium paranaensis can be distinguished from all valid species in the genus using the following combination of characters: worm length, number of proglottids, diamond-shaped bothridia lacking constriction, number of loculi on the distal surface of bothridium, and the lack of vaginal sphincter and external seminal vesicle.
巴拉那河莱茵绦虫新种（四叶目：绦虫纲）是从在阿根廷巴拉那河下游支流科拉斯蒂内河采集的淡水黄貂鱼福氏河魟中描述的。使用光学显微镜、扫描电子显微镜和组织学对标本进行了详细研究。巴拉那河莱茵绦虫可通过以下特征组合与该属所有有效物种区分开来：虫体长度、节片数量、无缢缩的菱形吸槽、吸槽远端表面的小室数量，以及缺乏阴道括约肌和外部精囊。
