These species were early placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic.^[2] In the revised classification to create monophyletic genera, these Mexican species were placed in the resurrected genus Leucolia by some taxonomic systems.^[3] However, a study published in 2021 showed that Leucolia was not available because of the principle of priority. The authors proposed the new genus Ramosomyia and in mid-2022 it was adopted by the North American Classification Committee of the American Ornithological Society and the International Ornithological Committee.^[4][5][1] As of that date the Clements taxonomy retains the three species in Leucolia and BirdLife International's Handbook of the Birds of the World in the earlier Amazilia.^[6][7]
