P. L. Sclater, 1859,
Often placed with S. kollari and S. candei in a separate genus Poecilurus, but no diagnosable differences from current genus. Genetic data#R show that present species is sister to S. cinerascens. Whether darker race whitii can be distinguished from extremes of adjacent populations of nominate, which varies clinally from NE to SW, or whether it is diagnosably distinct, merits investigation. Newly discovered population in SE Peru here included in whitii, as is nearby one in NW Bolivia, but these may represent an undescribed taxon#R. Proposed races neglecta (Ceará), supposedly paler rufous above and whiter below, and teretiala (Serra dos Carajás, in S Pará), described from three specimens as smaller and whiter below than nominate, both considered indistinguishable. Two subspecies recognized.
