Thus, the identical specific epithets never came into direct conflict until recently. But the black-chested eagle-buzzard's placement in a monotypic genus was always disputed, and several authors treated it in "Buteo". However, they overlooked that "Buteo melanoleucus" was the original name of the black-and-white hawk-eagle and thus as a senior homonym could not be applied to the later-described species. The correct specific name for the black-chested eagle-buzzard when placed in "Buteo", "Buteo fuscescens", was reestablished in the mid-20th century for a short time more by accident than anything else; as most late-20th-century researchers argued for retaining "Geranoaetus", this name was dismissed as erroneous and essentially forgotten.
