Taxonomic note
Previously listed as Chlorostilbon notatus (del Hoyo and Collar 2014), and before that as Chlorestes notata, but moved to current genus following a recent overhaul of all genera by NACC, based on McGuire et al. (2014), Stiles et al. (2017a, b) and others. Author and year of scientific description of species have continually been misquoted. Racial variation complex and possibly not constant; intermediate populations exist. Birds of Brazil S of Amazon formerly awarded subspecies cyanogenys. Two highly doubtful forms are known only from trade skins (one and two, respectively) from Bahia: C. subcaeruleus is probably a hyperchromatic aberration of present species; C. hypocyaneus may be a mutant of present species, or hybrid of present species with C. cyanus, or possibly even a valid species. Also, form Eucephala scapulata, known from single specimen from French Guiana, is probably a hybrid of present species with Thalurania furcata. Three subspecies currently recognized.
