Yellow-breasted Flycatcher (Tolmomyias flaviventris) - HBW 9, p. 340

French: Platyrhynque à poitrine jaune German: Gelbbauch-Breitschnabeltyrann Spanish: Picoplano Pechiamarillo
Other common names: Yellow-breasted Flatbill; Ochre-lored Flycatcher (N & E races aurulentus, dissors and flaviventris); Olive-faced Flycatcher (W Amazonian races viridiceps, zimmeri and subsimilis)

Taxonomy: Muscipeta flaviventris Wied, 1831, southern Bahia, Brazil.
Relationships within genus uncertain, pending completion of major genetic study. W Amazonian races (viridiceps, zimmeri, subsimilis) sometimes treated as a separate species on grounds of plumage and vocal differences. Taxonomic limits of all races, however, poorly delineated. Named taxon borbae, from Borba (R Madeira, in Brazil), considered an intergrade between viridiceps and nominate; collingwoodi, described from Trinidad, included within aurulentus. Six subspecies recognized.
