Tyrant-flycatchers (Tyrannidae)

Dusky-chested Flycatcher (Myiozetetes luteiventris) - HBW 9, p. 408

French: Tyran à gorge rayée German: Strichelbrust-Maskentyrann Spanish: Bienteveo Pechioscuro
Other common names: Orange-vented Flycatcher

Taxonomy: Elaenia luteiventris P. L. Sclater, 1858, River Napo, Ecuador.
Morphological and behavioural evidence suggests genus most closely related to Legatus; nesting behaviour links with Pitangus. Taxonomic history of this species somewhat turbulent; orginally described within genus Elaenia, and subsequently transferred back and forth between current genus and Tyrannopsis, largely because of its smaller size and peculiar coloration compared with present congeners. Molecular data indicate strong support for a clade consisting of present species and M. granadensis as sister-group to one formed by M. cayanensis and M. si.. View all taxonomy...

Taxonomy: Elaenia luteiventris P. L. Sclater, 1858, River Napo, Ecuador.
Morphological and behavioural evidence suggests genus most closely related to Legatus; nesting behaviour links with Pitangus. Taxonomic history of this species somewhat turbulent; orginally described within genus Elaenia, and subsequently transferred back and forth between current genus and Tyrannopsis, largely because of its smaller size and peculiar coloration compared with present congeners. Molecular data indicate strong support for a clade consisting of present species and M. granadensis as sister-group to one formed by M. cayanensis and M. similis. Validity of race septentrionalis uncertain. Two subspecies recognized.

Subspecies and Distribution:

  • septentrionalis Blake, 1961 - E Surinam, French Guiana and adjacent NE Brazil (Amapá).
  • luteiventris (P. L. Sclater, 1858) - E Ecuador and SE Colombia (S from Putumayo and Vaupés) E to SE Venezuela (S Bolívar), S to Amazonian Brazil (E to E Pará and W Maranhão, S to Rondônia and N Mato Grosso), E Peru (Loreto and Madre de Dios, probably also elsewhere) and extreme NW Bolivia (Pando, N La Paz).
