In accord with AOS-NACC (Chesser et al. 2020b), change the scientific name of Cozumel Emerald from Chlorostilbon forficatus to Cynanthus forficatus (Stiles et al. 2017a, b), based on genetic evidence that the traditional genus Chlorostilbon is not monophyletic, and this species is embedded within Cynanthus (McGuire et al. 2014, Hernández-Baños et al. 2020).
