Molecular systematics is bringing taxonomy into the 21st Century by updating our nomenclature to reflect phylogenetic relationships of taxa. This transformation is highly evidenced by massive changes in avian taxonomy, ranging from ordinal to subspecies changes. In this study, we employ target capture of ultraconserved elements to resolve genus-level systematics of a problematic group of honeyeaters (Aves: Meliphagidae). With near complete species-level taxon sampling of the Australo-Papuan species within the traditionally recognized Meliphaga and Oreornis, we investigate generic-limits using a genomic dataset. Likelihood and species tree methods confirm two clades within this group and found the New Guinea endemic Oreornis chrysogenys embedded within one of these clades. Our study supports earlier recommendations that Meliphaga Lewin, 1808 should be restricted to three species, M. aruensis, M. lewinii, and M. notata. We make a case for recognizing three genera in the remaining species, Oreornis van Oort, 1910, Microptilotis Mathews, 1912, and Territornis Mathews, 1924.
