Formicivora is a genus of insectivorous birds in the antbird family, Thamnophilidae.

These relatively small, long-tailed antbirds are strongly sexually dichromatic.

They are found in semi-open habitats in woodland and shrub in South America.

[4] The name of the genus Formicivora combines the Latin words formica for "ant" and -vorus "eating" from vorare "to devour".

[7] In contrast, the black-hooded antwren is not closely related to other Formicivora and may be better placed in its own genus.
