The evidence of vocalizations, morphology and nest architecture suggests that this species enjoys a close relationship with the east Brazilian endemics Scalloped Antbird (Myrmeciza ruficauda), White-bibbed Antbird (Myrmeciza loricata), and Squamate Antbird (Myrmeciza squamosa), which possibility is significant given that the genus Myrmeciza is almost certainly polyphyletic as currently constituted. In contrast to its apparent closest relatives, the Ferruginous-backed Antbird is a Guianan Shield endemic, where it inhabits the floor of tropical evergreen forest and old second growth. Once seen well, the Ferruginous-backed Antbird can be appreciated as one of the most beautiful and charismatic members of its genus, being largely warm brown above, with immaculately patterned spotting on the wing coverts, a patch of pale blue orbital skin, a deep black face and throat delineated by white on the neck and breast sides, and a buffy ventral region. Females differ from males in having the chin white, contrasting with the black face and upper breast.
