Nominate race and argentata differ distinctively in plumage (though loudsongs identical), but intervening races diaphora and toddi may represent clinal variation; research needed. “Myrmeciza dubia”, described from a single specimen from Pará, in E Amazonia, generally considered a synonym of present species. Four subspecies recognized.
