Rufous-backed Antwren

About the Rufous-backed Antwren

The rufous-backed stipplethroat (Epinecrophylla haematonota) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, Peru, and Venezuela. In its complex taxonomic history, Epinecrophylla haematonota has also been called the rufous-backed antwren, stipple-throated antwren, Napo stipple-throated antwren, and western stipple-throated antwren.

The rufous-backed stipplethroat was described by the English zoologist Philip Sclater in 1857 and given the binomial name Formicivora haematonota. It was later placed in genus Myrmotherula. Based on genetic and vocal studies it and seven other members of that genus were moved to the newly created genus Epinecrophylla. All were eventually named "stipplethroats" to highlight a common feature and to set them apart from Myrmotherula antwrens.

Since 2019 taxonomists have recognized these three subspecies within Epinecrophylla haematonota: E. h. haematonota (Sclater, PL, 1857) E. h. pyrrhonota (Sclater, PL & Salvin, 1873) E. h. fjeldsaai (Krabbe, Isler, ML, Isler, PR, Whitney, Álvarez A, J & Greenfield, 1999)
