Subspecies
No subspecies.
In the past, genus sometimes subsumed in Buthraupis, but this treatment not supported by recent molecular-genetic studies, which place it in a separate clade, with Wetmorethraupis as sister to it. In addition, members of present genus are smaller in size and shorter-tailed than Buthraupis, relatively uniform in plumage, behaviourally less social and occur mostly at lower elevations.
