White-shouldered Antbird

Akletos melanoceps

The white-shouldered antbird (Percnostola melanoceps) is a species of bird in the family Thamnophilidae. It is found in Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical swamps.

The white-shouldered antbird was described and illustrated by the German naturalist Johann Baptist von Spix in 1825 and given the binomial name Thamnophilus melanoceps. It was subsequently moved to the genus Myrmeciza. A molecular phylogenetic study published in 2013 found that Myrmeciza was polyphyletic. In the resulting rearrangement to create monophyletic genera this species was moved to the resurrected genus Akletos which had been introduced by the Polish ornithologist Andrzej Dunajewski in 1948.
