Issue
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 Potamotrygon schroederi does not correspond to this species in Rosa (1985a) – his “P. schroederi” actually represents a new species. Reproductive biology unknown. Additional references: Mago-Leccia (1970), Compagno & Cook (1995).
