Myrmotherula longicauda

Chontabamba, La Merced and La Gloria, Junín, Peru


Member of the “streaked antwren assemblage” (see M. brachyura). Vocalizations suggest that this and M. klagesi are sister-species. Plumage distinctions among races are not entirely clear, and ranges listed below are tentative; taxonomic status of recently discovered population inhabiting lowland flooded forest in Loreto (Peru) uncertain; further study required. Four subspecies recognized.

Subspecies and Distribution
  • M. l. soderstromi Gyldenstolpe, 1930 – E slope of Andes in S Colombia (Putumayo) and N Ecuador (Napo).
  • M. l. pseudoaustralis Gyldenstolpe, 1930 – E slope in S Ecuador (Morona-Santiago, Zamora-Chinchipe) and N Peru (S to Pasco).
  • M. l. longicauda Berlepsch & Stolzmann, 1894 – C Peru (N Junín).
  • M. l. australis Chapman, 1923 – SE Peru (Cuzco, Madre de Dios, Puno) and NW Bolivia (La Paz, S Beni, Cochabamba).
