Subspecies
No subspecies.
Genus as presently constituted may be polyphyletic. Anatomical evidence suggests that Planalto Tyrannulet (Phyllomyias fasciatus), Grey-capped Tyrannulet (Phyllomyias griseocapilla) and Sooty-headed Tyrannulet (Phyllomyias griseiceps) may be unrelated to others of genus, some or all of which possibly better placed in resurrected genus Tyranniscus. Appears to form a superspecies with Greenish Tyrannulet (Phyllomyias virescens) and Urich's Tyrannulet (Phyllomyias urichi) and probably closest to Urich's Tyrannulet (Phyllomyias urichi). All were for long considered conspecific, but differences in morphology (plumage pattern, wing and tail proportions), degree of sexual dimorphism, habitat and voice evident. Has been suggested that Sclater's Tyrannulet (Phyllomyias sclateri) also belongs in this group.
