French: Tyranneau à face jaune German: Gelbstreif-Kleintyrann Spanish: Mosquerito Peruano
Other common names: Tschudi’s Tyrannulet

Taxonomy: E[laenia] viridiflava Tschudi, 1844, Tulumayo, Junín, Peru.
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 Z. chrysops, but separated on basis of plumage and voice. Monotypic.

Distribution: E Andes of C Peru (Huanuco, Junín, Ayacucho).
