Known from the upper rio Xingu in the states of Pará and Mato Grosso. A single specimen was found in sympatry with Bryconadenos weitzmani in rio Curuá, tributary of rio Iriri, rio Xingu basin. The population from Campinápolis, rapids in rio Culuene, rio Xingu basin is under severe threat due to the recent impoundment of the rio Culuene in the exact stretch where the specimens were collected, and other known populations should be preserved.
