In accord with AOS-NACC (Chesser et al. 2020b), change the scientific name of Puerto Rican Emerald from Chlorostilbon maugaeus to Riccordia maugaeus (Stiles et al. 2017a, b), based on genetic evidence that the traditional genus Chlorostilbon is not monophyletic (McGuire et al. 2014, Hernández-Baños et al. 2020).
