Gnateaters (Conopophagidae)

Rufous Gnateater (Conopophaga lineata) - HBW 8, p. 745

French: Conophage roux German: Rotkehl-Mückenfresser Spanish: Jejenero Rojizo
Other common names: Silvery-tufted Gnateater; Caatinga Gnateater (cearae)

Taxonomy: Myiagrus lineatus Wied, 1831, near Vitória da Conquista, Bahia, Brazil.
See page 735. Apparently closest to, and perhaps forms a group with, C. roberti, C. peruviana, C. ardesiaca and C. castaneiceps, possibly also including C. melanogaster. Geographical limits of races uncertain; complex vocal variation, but the extent to which this corresponds with published ranges of named races is not known; in addition, plumage variation minimal throughout S half of range; much additional work and taxonomic revision required. Race cearae morphologically and vocally distinctive, and may merit species status. Described forms anomalu.. View all taxonomy...

Taxonomy: Myiagrus lineatus Wied, 1831, near Vitória da Conquista, Bahia, Brazil.
See page 735. Apparently closest to, and perhaps forms a group with, C. roberti, C. peruviana, C. ardesiaca and C. castaneiceps, possibly also including C. melanogaster. Geographical limits of races uncertain; complex vocal variation, but the extent to which this corresponds with published ranges of named races is not known; in addition, plumage variation minimal throughout S half of range; much additional work and taxonomic revision required. Race cearae morphologically and vocally distinctive, and may merit species status. Described forms anomalus from Paraguay (Alto Paraná) and rubecula from Brazil (Veadeiros, in Goiás) subsumed in, respectively, vulgaris and nominate. Also, two specimens from E Brazil (Ibiquera, in C Bahia) exhibit distinctive plumage differences, and possibly represent an unnamed taxon. Three subspecies provisionally recognized.

Subspecies and Distribution:

  • cearae Cory, 1916 - NE Brazil in N Ceará (Serra de Baturité); affinity with populations in Pernambuco and N Bahia requires confirmation.
  • lineata (Wied, 1831) - Pernambuco S to S Bahia, and S & W to Goiás; also N Mato Grosso do Sul (Serra das Araras).
  • vulgaris Ménétriés, 1835 - SC & SE Brazil (S Mato Grosso do Sul and Espírito Santo S to Rio Grande do Sul) to E Paraguay, NE Argentina (Misiones, Corrientes) and E Uruguay.
