Issue
Occurrence in Orinoco basin tentative, dependent upon identification of questionable synonym Oxydoras holdeni Fernández-Yépez; specimens of Oxydoras niger reported from Venezuela by Fernández-Yépez 1968:57 pertain to Oxydoras sifontesi Fernández-Yépez. Species-level distinctiveness of São Francisco and Amazonas Oxydoras not investigated.
