Family Typical Antbirds (Thamnophilidae)

Least Concern

Western Stipple-throated Antwren (Epinecrophylla haematonota)


French: Myrmidon cravaté German: Napoameisenschlüpfer Spanish: Hormiguerito dorsirrojo occidental
Other common names: Brown-backed Antwren (fjeldsaai)

Formicivora hæmatonota

P. L. Sclater

, 1857,

Chamicuros, Loreto, Peru


Until recently, considered conspecific with E. amazonica. Recent vocal and genetic analysis#R indicates that taxon fjeldsaai#R, treated as a full species in HBW, is better considered a race of present species (indistinguishable on voice although moderately distinct in plumage). Genetic evidence suggests that race pyrrhonota (which occurs sympatrically in E Andes of Colombia with E. spodionota#R) is distinctive, but it is vocally nearly identical to haematonota although, like fjeldsaai, moderately distinct in plumage. Three subspecies recognized.
