Puerto Rican Euphonia Chlorophonia sclateri andLesser Antillean Euphonia C. flavifrons are split from Hispaniolan (formerly Antillean) Euphonia C. musica (Clements 2007:627)

Summary: The Caribbean avifauna increases by two attractively plumaged species with the recognition that Puerto Rican Euphonia and Lesser Antillean Euphonia are distinct species from Hispaniolan Euphonia.

Details: The Chlorophonia musica complex (sensu Storer 1970) comprised nine subspecies of which, due to earlier taxonomic changes, only three now remain in the Antillean complex C. musica. These three, the Puerto Rican C. sclateri, Hispaniolan C. musica, and the Lesser Antillean C. flavifrons, were all originally described as separate species, and male plumages differ markedly. del Hoyo and Collar (2016) considered each of these separate species on the basis of morphology. However, no genetic comparisons appear to have been made for these three, and vocalizations are at least broadly similar so far as known (Mason et al. 2022, https://americanornithology.org/wp-content/uploads/2023/08/2023-B.pdf). Nevertheless, WGAC, NACC (Chesser et al. 2023), Gill et al. (2023, IOC v.13.2), and Clements et al. (2023) align with del Hoyo and Collar (2016) in now considering each of these taxa separate species based on their morphological differences that are equivalent to or exceed those exhibited by other euphonia species.
