Bare-eyed Antbird is a Brazilian endemic and the easternmost representative of the genus Rhegmatorhina. Like others of the genus, this species is an obligate ant-follower and thus one of the so-called ‘professional’ antbirds. It has a very limited range, occurring between the Rios Tapajós and Iriri/Xingu, in the states of Pará and Mato Grosso, in southeastern Amazonian Brazil. This species is dominant over all other such antbirds at army ant swarms, with the exception of the Black-spotted Bare-eye (Phlegopsis nigromaculata). Bare-eyed Antbirds seem to be largely found in terra firme, and rarely wander into seasonally flooded areas. The species is not especially sexually dimorphic, with females having a brownish-black head and throat, grading into yellowish-brown underparts, whereas these parts are blacker in males.
