Subspecies
No subspecies.
Despite superficial resemblance to Phyllomyias, genus appears to be more closely related to Phylloscartes. This species was formerly placed in a separate genus, Tyranniscus, but exhibits plumage and morphological features (wing pattern, proportionally long tail and bill, and derived characters of both syrinx and palate) typical of present genus. Often treated as conspecific with Golden-faced Tyrannulet (Zimmerius chrysops), but separated on basis of plumage and voice.
The following 2 subspecies are recognised:
flavidifrons (Sclater, PL, 1860) - South-western Ecuador (south-eastern Guayas south to western Loja).
