May form a superspecies with R. dimidiatus, R. melanogaster and R. bresilius. Molecular analysis indicates that levels of divergence between this species and R. melanogaster (1.1%) are lower than those generally found for other species in genus (2·4–4·0%); the two overlap slightly in range in N Peru (Marañón drainage), with some evidence of hybridization. Has hybridized with R. bresilius in E Brazil (SE Minas Gerais). Eight subspecies recognized.
