Subspecies
Taxonomy long disputed. Has frequently been thought to belong in family Mimidae. but recent DNA studies, however, strongly suggest that this species is neither a mimid nor a troglodytid, but an aberrant "sylvioid", a group that includes the babblers (Timaliidae) and the Old World warblers (Sylviidae). Species name often erroneously emended to atricapillus, but atricapilla is a Latin noun and is thus invariable.
The following 4 subspecies are recognised:
brachypterus Madarász, 1913 - Panama (eastern Darién) and north-western Colombia (east to Santa Marta region, south to northern Tolima).
atricapilla (Linnaeus, 1766) - Northern Venezuela, the Guianas, most of Brazil, Paraguay and extreme north-eastern Argentina.
nigrodorsalis Traylor, 1948 - Southern and south-eastern Colombia, eastern Ecuador and eastern Peru (south to Madre de Dios).
albovittatus d'Orbigny & Lafresnaye, 1837 - South-western Brazil (Acre) south to northern and eastern Bolivia (Beni, eastern Cochabamba, Santa Cruz).
