Typical Antbirds (Thamnophilidae)
Stripe-chested Antwren (Myrmotherula longicauda) - HBW 8, p. 579
French: Myrmidon à ventre blanc

Spanish: Hormiguerito Pechilistado
Taxonomy: Myrmotherula longicauda Berlepsch and Stolzmann, 1894, Chontabamba, La Merced and La Gloria, Junín, Peru.
Vocalizations suggest that this and M. klagesi are sister-species. Genetic and morphological analyses indicate that both are part of a monophyletic group that also includes M. brachyura, M. ignota, M. surinamensis, M. multostriata, M. pacifica, M. cherriei, M. sclateri and M. ambigua (the “streaked antwren assemblage”). Plumage distinctions among races are not entirely clear, and ranges listed below are tentative; further, taxonomic status of recently discovered population inhabiting lowland flooded forest in Loreto (Peru) unc..

Plumage distinctions among races are not entirely clear, and ranges listed below are tentative; further, taxonomic status of recently discovered population inhabiting lowland flooded forest in Loreto (Peru) uncertain; further study required. Four subspecies recognized.
Subspecies and Distribution:
- soderstromi Gyldenstolpe, 1930 - E slope of Andes in S Colombia (Putumayo) and N Ecuador (Napo).
- pseudoaustralis Gyldenstolpe, 1930 - E slope in S Ecuador (Morona-Santiago, Zamora-Chinchipe) and N Peru (S to Pasco).
- longicauda Berlepsch & Stolzmann, 1894 - C Peru (Junín).
- australis Chapman, 1923 - SE Peru (Cuzco, Madre de Dios, Puno) and NW Bolivia (La Paz, S Beni, Cochabamba).
