Author: Fernández-Yépez, 1958
FBname: Rosette river stingray
Remark: Holotype was originally in the private collection of A. Fernandez-Yepez (AFY 51289). Distribution of this species was expanded by Castex & Yagolkowski (1970) to include the Negro river of the Amazonas basin. Note that the species we recognize as <i>Potamotrygon schroederi</i> does not correspond to this species in Rosa (1985a) – his “<i>P. schroederi</i>” actually represents a new species. Reproductive biology unknown. Additional references: Mago-Leccia (1970), Compagno & Cook (1995).
