Description
Males can be distinguished from those of the marsh antwren by their black underparts and thighs, very dark grey-brown upperparts, and a smaller exposed culmen. Females are distinguished by their very dark grey-brown upperparts and flanks, and smaller exposed culmen.
Distribution and habitat
The antwren has been found in fifteen small, isolated areas in the east of the state of São Paulo, not far from the city of São Paulo, in south-eastern Brazil. The sites lie within the headwaters of the Paraíba do Sul and Tietê Rivers, at elevations of 600–760 m. There it inhabits marshes with relatively tall (60–250 cm) vegetation. Much of its habitat is degraded and threatened by agricultural, industrial and residential development.
