Often separated in monospecific Psilorhinus, but included in current genus following findings of recent phylogenetic study#R. Has hybridized with C. formosus in S Mexico. Two morphs, largely random in occurrence, white-tipped morph found at relatively high frequencies in arid and mesic regions, brown-tailed morph predominating in more humid areas; in Mexico, white-tipped morph, formerly treated as a separate species, “C. mexicanus”, recorded N to C Veracruz (Plan del Río, 19°12’ N), and brown-tailed morph found S to Montecristo, in Tabasco. Proposed race cyanogenys (Pearl Cay Lagoon, in Nicaragua) included in nominate. Three subspecies recognized.
