The Guianan Warbling-Antbird can be found from eastern Venezuela, through the Guianas, to northeast Amazonian Brazil.
It has a black crown streaked with white, white supercilium, olive-grey upperparts, back spotted black and white, with orange fading to white underbelly.
The main component of its diet is arthropods; these are mostly insects, including grasshoppers and crickets, cockroaches, praying mantises, stick insects and the larvae of butterflies and moths.
