The three species in the genus were previously placed in the genus Cercomela. A molecular phylogenetic study published in 2010 found that Cercomela was polyphyletic and that the type species Cercomela melanura (the blackstart) lay in a clade containing members of Oenanthe.[1] A more comprehensive study published in 2012 confirmed the earlier results.[2] In order to create monophyletic genera the species assigned to Cercomela were moved into other genera.[3] Three species were placed in the resurrected genus Emarginata that had been introduced by the English ornithologist George Ernest Shelley in 1896.[4]

The three species in the genus are:[3]
