Tyrant-flycatchers (Tyrannidae)

White-tailed Tyrannulet (Mecocerculus poecilocercus) - HBW 9, p. 279

French: Tyranneau à queue blanche German: Weißschwanz-Tachurityrann Spanish: Piojito Coliblanco

Taxonomy: Serpophaga poecilocerca P. L. Sclater and Salvin, 1873, Púellaro, 8000 feet [c. 2440 m], Pichincha, Ecuador.
Genus as presently constituted is probably polyphyletic, and in need of further study. Syringeal characters suggest that present species and M. hellmayri, which form a superspecies, as well as M. stictopterus, are possibly close to Camptostoma, Inezia and relatives. Monotypic.

Distribution: Forested Andes from N Colombia S to SE Peru (S to Cuzco and Madre de Dios).
