Genetic and morphological analyses indicate that this species and M. brachyura, M. surinamensis, M. multostriata, M. pacifica, M. cherriei, M. klagesi, M. longicauda, M. sclateri and M. ambigua represent a monophyletic group (the “streaked antwren assemblage”). Present species is closely related to first of those, and nominate race formerly considered conspecific, but differs in vocalizations and plumage. Race obscura often treated as a separate species, but vocally indistinguishable from nominate. Two subspecies recogn.. View all taxonomy...
Genetic and morphological analyses indicate that this species and M. brachyura, M. surinamensis, M. multostriata, M. pacifica, M. cherriei, M. klagesi, M. longicauda, M. sclateri and M. ambigua represent a monophyletic group (the “streaked antwren assemblage”). Present species is closely related to first of those, and nominate race formerly considered conspecific, but differs in vocalizations and plumage. Race obscura often treated as a separate species, but vocally indistinguishable from nominate. Two subspecies recognized.
Subspecies and Distribution:
- ignota Griscom, 1929 - E Panama (Caribbean slope in Canal area and San Blas, Pacific slope in E Panamá and Darién), W & N Colombia (Pacific slope and along N base of Andes E to Santander) and NW Ecuador (Esmeraldas, SW Imbabura, NW Pichincha).
- obscura J. T. Zimmer, 1932 - SC & E Colombia (locally along base of Andes S from Meta, and in Guianía and Vaupés), E Ecuador, NE Peru (S to Pasco and Ucayali), and SW & WC Amazonian Brazil (extreme SW S to NW Acre, and EC Amazonas along R Solimões).
