Adult individuals have a slate-gray crown and nape, with a bright olive-green back and rump. Their lores and the area surrounding the eye are white, marked with a faint dusky stripe that passes through the eye. The lower part of their face is pale gray. Their wings are dusky, with bright yellow edges on the flight feathers and the tips of the coverts; the yellow edges on the coverts form two distinct wing bars. Their tail is dusky olive. Their throat is grayish white, their breast is pale gray, their flanks are bright yellow-green, and their belly is whitish. They have a brown iris, a small, rounded blackish bill, and gray legs and feet. This species is found in eastern Brazil, occurring in south-central Bahia, and extending further south from Minas Gerais and Espírito Santo to northeastern Rio Grande do Sul. It lives in the interior and edges of humid primary forest and secondary forest in the tropical zone. Most of its population occurs at elevations between 750 and 1,850 m (2,500 and 6,100 ft), though local populations can be found as low as sea level.
