Tyrant-flycatchers (Tyrannidae)

Ochre-bellied Flycatcher (Mionectes oleagineus) - HBW 9, p. 309

French: Pipromorphe roussâtre German: Ockerbauch-Pipratyrann Spanish: Mosquero Aceitunado
Other common names: Oleaginous Flycatcher/Pipromorpha

Taxonomy: M[uscicapa] oleaginea M. H. K. Lichtenstein, 1823, Bahia, Brazil.
Closely allied to M. macconnelli and M. rufiventris; the three were for long placed in a separate genus, Pipromorpha, on basis of specialized outer primaries of male, but they share numerous characters (including unusual lek breeding system) with both M. striaticollis and M. olivaceus. Races fall into two groups according to plumage, the “assimilis group” and the “nominate group”. Variation within former sufficient to warrant retention of several names, but obscurus (El Salvador), dyscolus (W Costa Rica and extreme W Panam.. View all taxonomy...

Taxonomy: M[uscicapa] oleaginea M. H. K. Lichtenstein, 1823, Bahia, Brazil.
Closely allied to M. macconnelli and M. rufiventris; the three were for long placed in a separate genus, Pipromorpha, on basis of specialized outer primaries of male, but they share numerous characters (including unusual lek breeding system) with both M. striaticollis and M. olivaceus. Races fall into two groups according to plumage, the “assimilis group” and the “nominate group”. Variation within former sufficient to warrant retention of several names, but obscurus (El Salvador), dyscolus (W Costa Rica and extreme W Panama) and lutescens (W Panama, including Coiba I) merged with assimilis, because they represent barely discernible intermediate forms within a broad N-S cline. Geographical variation across widespread “nominate group” exceedingly minor, while individual, age-specific and sexual variation considerable; described races intensus (SE Venezuela and W Guyana), wallacei (the Guianas, NE & E Amazonian Brazil E of R Negro), chloronotus (Amazon Basin), hauxwelli (E Ecuador and NE Peru N of Amazon) and maynanus (EC Peru S to Pasco) all treated as synonyms of nominate. Seven subspecies recognized.

Subspecies and Distribution:

  • assimilis P. L. Sclater, 1859 - humid lowlands from S Mexico (Veracruz, Tabasco, Yucatán Peninsula) S to E Costa Rica and W Panama.
  • parcus Bangs, 1900 - E Panama (E from Canal Zone) E to N Colombia and NW Venezuela (Zulia, Táchira, Mérida).
  • abdominalis (Phelps, Sr & Phelps, Jr, 1955) - N Venezuela (Distrito Federal and Miranda E to Cerro Negro).
