This antshrike inhabits the Amazon basin along major rivers. It mainly forages in dense understory on river-created islands, and male and female wing markings differ.
The male is black with white edging on the wing coverts and a white shoulder mark. The female lacks white wing markings. Both sexes have a partly hidden white patch on the back.
It forages in dense understory on river-created islands and is also recorded in similar river-edge habitat, though less often.
