A new species of tetraphyllidean (Cestoda) from the largespot river stingray, potamotrygon falkneri (Potamotrygonidae: Chondrichthyes), from the Paran Basin
Rhinebothrium paranaensis n. sp. (Tetraphyllidea: Cestoda) is described from the freshwater stingray Potamotrygon falkneri collected in the Colastin River, a tributary to the Lower Paran River in Argentina. The specimens were studied in detail using light and scanning electron microscopy and histolo...
