A new species of Leporinus Agassiz is described from the rio Curua, a tributary of the rio Iriri, rio Xingu basin, Serra do Cachimbo, Para State, Brazil. The new species is diagnosed by the color pattern, which consists of eight to ten midlateral round dark blotches plus 20 to 40 smaller ones scattered over the body, dental formula 3/4, subinferior to inferior mouth, 37 to 38 lateral line scales, 4/3-4 transversal series of scales, and 12 circumpeduncular scale series. The new species most closely resembles L. octomaculatus and L. reticulatus from the upper Tapajos basin, and L. marcgravii and L. microphthalmus from the rio Sao Francisco and the rio Paranaiba, respectively. Based on recently collected specimens, L. reticulatus is re-diagnosed as having an allometric elongation of the snout.
