The Bicoloured Antbird is distributed from Honduras to Panama and into Colombia, Ecuador, Peru and Brazil north of the Amazon and west of the rio Negro. These birds were photographed on the right bank of the rio Negro so were at the edge of their range. It is the lateralis sub-species in this area.

The "bicoloured" aspect is the brown above and the white below but possibly the most striking feature, at least east of the Andes, is the blue area around the eye.
