The species account classifies this antbird as a forest-dwelling invertivore. In Anapu, Pará, two nests were documented in dense terra firme forest in April 2016.
Oiseaux.net lists a body mass of 12.3 g.
The two Anapu nests were basket-shaped and made with vines and dry leaves; they were found in April 2016. During 196 minutes at one nest, observers saw only the male care for the nestlings. The authors state that this short, preliminary observation is not conclusive.
