It is found in Ecuador and Peru. == Taxonomy and systematics == The lunulated antbird was described and illustrated by the English ornithologists Philip Sclater and Osbert Salvin in 1873 and given the binomial name Pithys lunulatus. The species was subsequently included in the genus Gymnopithys. It was moved to a newly erected genus, Oneillornis, based on the results of a molecular phylogenetic study published in 2014. It shares the genus with the white-throated antbird (O. salvini), which has been treated as conspecific. The lunulated antbird is monotypic. == Description == The lunulated antbird is 13 to 14.5 cm (5.1 to 5.7 in) long and weighs 22 to 26 g (0.78 to 0.92 oz). Adult males are mostly gray.
