''Formicivora'' is a genus of birds in the family Thamnophilidae. These relatively small, long-tailed antbirds are strongly sexually dichromatic. They are found in forest, woodland and shrub in South America, although a single species (''F. grisea'') also occurs in Panama. ==Species== The Sincorá antwren was only described in 2007. While traditionally placed in its own genus ''Stymphalornis'', the marsh antwren belongs in ''Formicivora''.〔Buzzetti, Belmonte-Lopes, Reinert, Silveira & Bornschein. (2013). "A new species of Formicivora Swainson, 1824 (Thamnophilidae) from the state of São Paulo, Brazil". Revista Brasileira de Ornitologia 21 (4): 269–291.〕 In contrast, the black-hooded antwren is not closely related to other ''Formicivora'' and better moved to its own genus.〔 * Narrow-billed antwren, ''Formicivora iheringi'' * White-fringed antwren, ''Formicivora grisea'' * * Southern white-fringed antwren, ''Formicivora (grisea) grisea * * Northern white-fringed antwren, ''Formicivora (grisea) intermedia * Black-bellied antwren, ''Formicivora melanogaster'' * Serra antwren, ''Formicivora serrana'' * Restinga antwren, ''Formicivora littoralis'' * Black-hooded antwren, ''Formicivora erythronotos'' * Rusty-backed antwren, ''Formicivora rufa'' * Sincorá antwren, ''Formicivora grantsaui''〔Gonzaga, Carvalhaes & Buzzetti (2007).
