Verbreitung und Lebensraum

The bare-eyed antbird has a limited range in southeastern Amazonian Brazil. It is bounded by the Amazon on the north, the Rio Tapajós on the west, and the Rio Xingu on the east. Its southern border is not well known but extends at least to the Teles Pires in northern Mato Grosso state. The species almost entirely inhabits the understorey of very humid terra firme primary rainforest, though it has also been recorded in várzea. Its range is entirely below 400 m (1,300 ft) of elevation.
