Subspecies
No subspecies.
Monotypic genus, in many respects transitional between Phyllomyias and Myiopagis, but anatomical evidence suggests closer relationship to latter. Birds from Panama named as subspecies panamensis and birds from northern Bolivia as benii. However, in examination of large series of specimens both considered indistinguishable from other populations.
