Abstract

Four species of ectoparasite crustaceans are registered for the first time from the Orinoco River Basin (Colombia) in freshwater stingrays of the family Potamotrygonidae, genus Potamotrygon. Two belong to the Branchiura subclass, Argulidae family: Dolops reperta (Bouvier, 1899) and D. striata (Bouvier, 1899), and two to the Isopoda Order, corresponding to the families Cymothoidae and Corallanidae, represented by the species Braga cigarra (Szidat & Schubart, 1960) and Excorallana delaneyi (Stone & Heard, 1989), respectively.
