Brown-backed Antwren (Myrmotherula fjeldsaai) - HBW 8, p. 586
French: Myrmidon de Fjeldsa
Spanish: Hormiguerito del Yasuní
Other common names: Yasuní Antwren
Taxonomy: Myrmotherula fjeldsaai Krabbe et al., 1999, Río Tiputini, Napo, Ecuador.
Forms a superspecies with M. spodionota and M. haematonota. Genetic, morphological and behavioural analyses indicate that the three are part of a monophyletic group that also includes M. gutturalis, M. fulviventris, M. leucophthalma, M. ornata and M. erythrura (the “stipple-throated antwren assemblage”), and which may not be closely related to other species placed in the genus. Monotypic.
Distribution: SE Ecuador (S & W of R Napo) and extreme NC Peru (N Loreto S to C R Tigre).
