Tyrant-flycatchers (Tyrannidae)
Sulphur-bellied Flycatcher (Myiodynastes luteiventris) - HBW 9, p. 413
French: Tyran tigré
German: Nördlicher Fleckenmaskentyrann
Spanish: Bienteveo Ventriazufrado
Taxonomy: Myiodynastes luteiventris P. L. Sclater, 1859, Orizaba, Veracruz, Mexico.
Affinities of genus uncertain; for long hypothesized as being closest to Conopias, largely on basis of similar hole-nesting tendencies. Genus probably monophyletic, although this only weakly supported by recent analyses of molecular-sequence data (likely due to inappropriate markers for the apparently long branches and deep level of divergence within genus). Results of separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence strongly suggests that present species is sister to M. maculatus, and that the two are sister-group ..

Affinities of genus uncertain; for long hypothesized as being closest to Conopias, largely on basis of similar hole-nesting tendencies. Genus probably monophyletic, although this only weakly supported by recent analyses of molecular-sequence data (likely due to inappropriate markers for the apparently long branches and deep level of divergence within genus). Results of separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence strongly suggests that present species is sister to M. maculatus, and that the two are sister-group to a clade consisting of M. hemichrysus and M. chrysocephalus. Specimens S from Guatemala evidently have heavier streaking on chest and throat and smaller bill than birds from Mexico, but differences deemed too inconstant to warrant subspecific separation. Monotypic.
Distribution: Breeds SW USA (mountains in S Arizona), Mexico (S on both slopes from Sonora, E Nuevo León and Tamaulipas), Guatemala and Belize S to Costa Rica. Winters E Ecuador, E Peru, extreme W Brazil (along R Juruá, in Acre) and Bolivia (S to Cochabamba and W Santa Cruz).
