The Salvadori’s Antwren is endemic to southeast Brazil, where most of the recent available records are from the Serra da Bocaina and Serra do Mar in southern Rio de Janeiro and adjacent São Paulo states, although there are also records from Minas Gerais, Espírito Santo, northeast Santa Catarina, and Bahia. The species’ current range appears to be highly fragmented and it is now rare, being consequently listed as Vulnerable according to IUCN criteria. Over its core range, males especially should be easily identified, by the dark grey plumage, with a black bib and white-spotted wing coverts, as the similar White-flanked Antwren (Myrmotherula axillaris) only reaches south to central Rio de Janeiro. The Salvadori’s Antwren is perhaps most frequently encountered within mixed-species flocks of insectivores in the understory; these typically also include various foliage-gleaners, Red-crowned Ant-Tanagers (Habia rubica), and sometimes the only marginally more numerous Unicolored Antwren (Myrmotherula unicolor).
