This small antwren lives in tall forests of eastern Brazil and often forages with mixed-species bird flocks.
The female has a gray back and white marks on the wings and tail. The account used here does not describe the male's plumage in detail.
Pairs or small family groups travel with mixed-species flocks and search leaves and vines about 3–9 m above the ground. Most observed foraging was at 5–7 m.
