Tyrant-flycatchers (Tyrannidae)

Sulphur-bellied Tyrannulet (Mecocerculus minor) - HBW 9, p. 280

French: Tyranneau soufré German: Gelbbauch-Tachurityrann Spanish: Piojito Azufre

Taxonomy: Leptopogon minor Taczanowski, 1879, Tambillo, Cajamarca, Peru.
Genus as presently constituted is probably polyphyletic, and in need of further study. Syringeal characters suggest that present species and M. calopterus are possibly related to Phyllomyias, specifically to Tyranniscus if latter resurrected. Monotypic.

Distribution: Andes of W Venezuela (Táchira), and locally in E range in Colombia, E Ecuador (one record from W slope) and N Peru (S to Huánuco).
