Formerly placed in a monospecific Xanthoura. Races fall into two groups, “luxuosus group” in Central America, and “yncas group” in Andes; these sometimes treated as two separate species, the luxuosus group differing in its shorter frontal tuft (2); smaller overall size (allow 1); green-tinged underparts in some but not all races (ns); dark iris in some but not all races (ns); more clear-cut colour transition from crown to mantle (1); and possibly higher pitch to the typical rapid series of cracking notes (ns). Race luxuosus intergrades with vividus in SE Sierra de Tuxtla and Catemaco region of S Veracruz. Race cozumelae sometimes synonymized with maya. Proposed race andicola (Andes of Mérida, Venezuela) included in cyanodorsalis. Thirteen subspecies recognized.
