Was thought to be a synonym of Duopalatinus since the single species of P. barbatus was found to be a synonym of Duopalatinus goeldii, but further study revealed that P. barbatus and D. goeldii were synonyms of P. mucosus (Vaillant, 1880). Description: The barbels reach up to three times the length of the body. The head is high and narrows with a subterminal mouth. The maxillary barbels display a membranous thickening at the base. The fontanel is large and thin that arrives just before the dorsal plate, the humeral process is visible. Species of average bearing grow to about 20cm SL. Colouration: The body colour can be of brown or grey on the back combined with the ventral area which is clear in colour. Usually there is circular spots in the flanks that can vary in amount. The fins are translucent. Remarks: Catalogued as being from the Amazon and Orinoco Rivers but the last two (penultimate) thumbnail juvenile specimens were captured in the Madre De Dios in southern Peru and photographed by the image contributor.
