Present species and H. constantii occasionally separated in genus Anthoscenus on basis of squarish tail, rounded rectrices and details of bill morphology; the distinguishing features, however, vary in a continuum between these species and H. furcifer, with H. squamosus occupying intermediate position, and treatment of all four as congeners now generally considered more appropriate. Several additional races described, notably veraguensis (Panama), chalcurus (Costa Rica), stuartae (Colombia) and caeruleiceps (Bolivia), but most have not been sustained and now included within nominate; masculinus (SC Mexico) considered a synonym of pallidiceps, but separation of latter from nominate has itself been questioned. Three subspecies currently recognized.
