This species is widespread in nature although the true extent of its range is an issue for debate. Officially its been recorded from Venezuela, Guyana, Suriname, French Guiana, Colombia, Ecuador, Peru, Bolivia and Brazil in various rivers including the rios Amazon, Orinoco, Negro, Xing and Araguia. However there is evidence to suggest that it may be confined to Guyana with collections at other localities perhaps comprising other species.
