Naming
Zeledon's antbird was at one time treated as a subspecies of the blue-lored antbird. It was also previously included in the genus "Myrmeciza". A molecular phylogenetic study published in 2013 found that "Myrmeciza", as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera Zeledon's antbird was moved to the newly erected genus "Hafferia".The common name and Latin binomial commemorate the Costa Rican ornithologist José Cástulo Zeledón.

Food
Zeledon's antbird feeds on insects, and regularly follows swarms of army ants in order to catch prey flushed by the swarms, but it is not an obligate ant-follower like some species of antbirds.References:
