Similar to P. anthophilus, both species apparently lacking close relatives. Includes proposed taxon P. nigrirostris, based on a unique specimen of nominate race having uniformly black bill. Proposed race pinheiroi (from Minas Gerais, in Brazil) is synonymized with nominate#R. Two subspecies recognized.
