Subspecies
Genus formerly included with Tityra in the Cotingidae, but transferred to present family because of several shared, derived features of the skull and syrinx. Because both genera exhibit similarity to cotingids in many other features, some authors prefer to leave them in that family or to treat them as representing a separate family (Tityridae). Phylogenetic affinity of present species unknown. Possibly closest to to Cinnamon Becard (Pachyramphus cinnamomeus). They are sometimes treated as a single zoogeographical species, essentially replacing each other geographically, but slight morphological differences between them considered by most authorities sufficient for treatment as distinct species.
The following 5 subspecies are recognised:
intermedius von Berlepsch, 1879 - Northern Venezuela (Falcón and Lara east to Sucre).
parui Phelps & Phelps Jr, 1949 - Base of Cerro Parú, in Amazonas (southern Venezuela).
saturatus Chapman, 1914 - South-eastern Venezuela (south-eastern Bolívar), eastern Colombia (R Dudita and Vaupés south to Meta), eastern Ecuador, north-eastern and eastern Peru (Loreto, Cuzco), northern Brazil (Amazonas, Acre and Rondônia east to Manacapurú and R Purús) and northern Bolivia.
amazonus Zimmer, JT, 1936 - Northern Brazil (both banks of Amazon from eastern Amazonas and Pará east to R Tocantins and Maranhío).
castaneus (Jardine & Selby, 1827) - North-eastern , south-eastern and southern Brazil (northern Bahia south to south-eastern Goiás, Mato Grosso do Sul and northern Rio Grande do Sul), south-eastern Paraguay and north-eastern Argentina (Misiones).
