Adult males have a black crown and nape, a wide whitish supercilium, a black stripe through the eye, and black and white or pale yellow mottled ear coverts. Their upperparts are mostly olive-gray with scattered black patches, yellow uppertail coverts, and white tips on their outer scapulars. Their wing coverts are black with white tips; their flight feathers are olive-brown tinged dark gray with bright cinnamon-rufous edges. Their tail is mostly dark gray with white tips on the feathers and an entirely white outermost pair. Their throat and underparts are light yellow with an olive tinge on the sides.

Areale e habitat

The rufous-margined antwren has a disjunct distribution. A small population is found north of the Rio São Francisco in Brazil's Pernambuco state. The other population is found from Bahia in southeastern Brazil south into Paraguay and northeastern Argentina. It primarily inhabits the interior of humid evergreen Atlantic Forest, less often its edges, and locally in restinga woodlands on white-sand soils. It typically is found from the forest's mid-storey to its subcanopy and favors dense vine tangles. In elevation it ranges from sea level to about 1,100 m (3,600 ft).
