Golden-faced Tyrannulet (Zimmerius chrysops) - HBW 9, p. 297

French: Tyranneau à face d’or German: Goldgesicht-Kleintyrann Spanish: Mosquerito Caridorado
Other common names: Loja Tyrannulet (flavidifrons)

Taxonomy: Tyrannulus chrysops P. L. Sclater, 1859, Zamora, Zamora-Chinchipe, Ecuador.
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. viridiflavus, but separated on basis of plumage and voice. Races albigularis and flavidifrons possibly represent a separate species.

Proposed race molestus (described from Cauca, in W Andes of Colombia) merged with nominate. Five subspecies recognized.
