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. Formerly placed in a genus Xanthomyias along with Greenish Tyrannulet (Phyllomyias virescens). It has been suggested that it may belong in a superspecies formed by Greenish Tyrannulet (Phyllomyias virescens), Reiser's Tyrannulet (Phyllomyias reiseri) and Urich's Tyrannulet (Phyllomyias urichi).
Proposed taxon Tyranniscus australis (Phyllomyias australis) is regarded as a synonym for this species.
The following 2 subspecies are recognised:
subtropicalis (Chapman, 1919) - Eastern Andes of south-eastern Peru (Cuzco).
sclateri Berlepsch, 1901 - Eastern Andes of Bolivia (La Paz south to Tarija) and north-western Argentina (Jujuy south to Tucumán).
