Typical Antbirds (Thamnophilidae)
Rusty-backed Antwren (Formicivora rufa) - HBW 8, p. 615
French: Grisin roux
German: Zimtrücken-Ameisenfänger
Spanish: Hormiguerito Dorsirrufo
Taxonomy: Myiothera rufa Wied, 1831, interior of Bahia, Brazil.
Morphological, vocal and molecular studies indicate that, with exception of F. iheringi, all species placed in current genus form a well-defined group. According to recent extensive morphological and vocal study, present species is closest to F. grisea and Stymphalornis acutirostris; close relationship to former also supported by genetic study. Plumage variation occurs within races as currently defined, and nominate race and chapmani possibly intergrade; also, possible regional variation in vocal repertoires; further study needed. Three subspecies recognized.
