Typical Antbirds (Thamnophilidae)

Pacific Antwren (Myrmotherula pacifica) - HBW 8, p. 578

French: Myrmidon du Pacifique German: Westlicher Strichelameisenschlüpfer Spanish: Hormiguerito del Pacífico
Other common names: Pacific Streaked Antwren

Taxonomy: Myrmotherula surinamensis pacifica Hellmayr, 1911, Buenaventura, Valle del Cauca, Colombia.
Until recently considered conspecific with M. surinamensis and M. multostriata, but vocal and plumage characters indicate that they are separate species; appears to be most closely related to M. cherriei. Genetic and morphological analyses indicate that all four species are part of a monophyletic group that also includes M. brachyura, M. ignota, M. klagesi, M. longicauda, M. sclateri and M. ambigua (the “streaked antwren assemblage”). Monotypic.

Distribution: Panama (E from E Bocas del Toro on Caribbean slope, from Panamá on Pacific slope), W & N Colombia (Pacific slope, N base of Andes E to Santander, and Magdalena Valley S to Cundinamarca) and W Ecuador (S to E Guayas, Chimborazo and NW Azuay).
