Endemic to Brazil, the Serra Antwren is in many ways a typical Formicivora, and is distributed from northeast Minas Gerais south to northwest Rio de Janeiro, with two subspecies being generally recognized. Furthermore, the globally threatened Restinga Antwren (Formicivora littoralis), which was described as a subspecies of the present species, but subsequently elevated to species status, appears identical to the Serra Antwren in vocalizations and might be better treated as a subspecies of the Serra Antwren once more. Serra Antwrens are usually observed in pairs or small family groups, which sometimes join small mixed-species flocks of other insectivores, in the understory of semi-humid evergreen forest edges, dry scrub, second-growth woodland, and is even apparently capable of colonizing Eucalyptus plantations.
