Subspecies
Trogon violaceus (Sibley and Monroe 1990, 1993; Stotz et al. 1996) has been split into Violaceous Trogon (Trogon violaceus) and Gartered Trogon (Trogon caligatus) following SACC (2009).

DNA studies suggest possibly closest to White-tailed Trogon (Trogon viridis) and Blue-crowned Trogon (Trogon curucui). Subspecies caligatus and ramonianus have both been treated as separate species by some authors. Northernmost subspecies commonly labelled as braccatus, but name sallaei has priority. Extensive individual variation in degree of bronzy tinge on back in nominate and subspecies caligatus led to description of rossi, now considered a synonym of nominate.

The following 6 subspecies are recognised:

  • sallaei Bonaparte, 1856   -  Caribbean slope of eastern and southern Mexico, also Pacific slope of southern Mexico, and Guatemala, Belize, El Salvador and northern Honduras; possibly this subspecies in Nicaragua. Considered by some authors to be a subspecies of Gartered Trogon (Trogon caligatus).
  • concinnus Lawrence, 1862   -  Costa Rica, Panama (except Caribbean slope of Darién), western Colombia, western Ecuador and north-western Peru. Considered by some authors to be a subspecies of Gartered Trogon (Trogon caligatus).
  • caligatus Gould, 1838   -  Eastern Mexico to north-western SA. Considered by some authors to be a distinct species, Gartered Trogon (Trogon caligatus).
  • violaceus J. F. Gmelin, 1788   -  Eastern Venezuela, the Guianas and adjacent northern Brazil; Trinidad.
  • ramonianus Deville and Des Murs, 1849   -  Amazonian areas of Colombia, Ecuador, Peru, Bolivia and Brazil. Also penetrates southern Venezuela (upper R Orinoco). Considered by some authors to be a distinct species, Amazonian Trogon (Trogon ramonianus).
  • crissalis (Cabanis and Heine, 1863)   -  North-eastern Brazil on southern bank of lower R Amazon and tributaries (east of R Tapajós). Considered by some authors to be a subspecies of Amazonian Trogon (Trogon ramonianus).
