Subspecies
Phylogenetic affinity of present species unknown. Has been suggested that it is closely related to One-colored Becard (Pachyramphus homochrous), Pink-throated Becard (Pachyramphus minor) and Crested Becard (Pachyramphus validus), or even conspecific with One-colored Becard (Pachyramphus homochrous) and Pink-throated Becard (Pachyramphus minor) and all are sometimes combined in a separate genus, Platypsaris, differing from present genus in nest shape and placement, as well as in some vocal and minor morphological characters. Racial variation poorly understood.
