Subspecies
No subspecies.
Genus as presently constituted may be polyphyletic. Anatomical evidence suggests that present species may be closest to Planalto Tyrannulet (Phyllomyias fasciatus) and Sooty-headed Tyrannulet (Phyllomyias griseiceps) and that all perhaps unrelated to others of genus, some or all of which possibly better placed in resurrected genus Tyranniscus. Has been placed by some authors in genus Oreotriccus, which originally contained only Plumbeous-crowned Tyrannulet (Phyllomyias plumbeiceps), but considered not allied to latter.
