Subspecies
May prove to be a member of an obligate ant-following clade. Relationships uncertain. Retained in same genus as White-plumed Antbird (Pithys albifrons) on grounds of similarities in vocalizations, but further study required. Until recent rediscovery, some authors considered that present species might be a hybrid of White-plumed Antbird (Pithys albifrons) and some other antbird species. Determination of precise location of type locality problematic, partly because many villages in the region have same name, and also due to changing national boundaries.
