Rufous-winged Tyrannulet (Mecocerculus calopterus) - HBW 9, p. 280

Taxonomy: Formicivora caloptera P. L. Sclater, 1859, Pallatanga, Chimborazo, Ecuador.
Genus as presently constituted is probably polyphyletic, and in need of further study. Syringeal characters suggest that present species and M. minor are possibly related to Phyllomyias, specifically to Tyranniscus if latter resurrected. Monotypic.

Distribution: Andes of W & SE Ecuador and N Peru (S to Lambayeque and La Libertad).
