Subspecies
Morphological, vocal and molecular studies indicate that, with exception of Narrow-billed Antwren (Formicivora iheringi), all species placed in current genus form a well-defined group. Considered to form a clade with Serra Antwren (Formicivora serrana) and Restinga Antwren (Formicivora littoralis), and all three have sometimes been treated as conspecific.
