Possibly closest to T. curucui, T. elegans (with T. ambiguus), T. mexicanus, T. collaris and T. personatus; DNA studies suggest that T. elegans (with T. ambiguus), T. collaris and T. personatus may be nearest relatives. Six subspecies recognized.

Subspecies and Distribution
  • T. r. tenellus Cabanis, 1862 – E Honduras, Nicaragua, both slopes of Costa Rica (except NW) and Panama, and extreme NW Colombia.
  • T. r. cupreicauda (Chapman, 1914) – W Colombia and NW Ecuador.
  • T. r. rufus J. F. Gmelin, 1788 – E Venezuela and the Guianas to N Brazil (R Negro region and Amapá).
  • T. r. sulphureus Spix, 1824 – SE Colombia, E Ecuador, NE Peru, W Brazil (E to R Negro and R Madeira) and N Bolivia.
  • T. r. amazonicus Todd, 1943 – NC Brazil (lower Amazon Valley).
  • T. r. chrysochloros Pelzeln, 1856 – Paraguay, NE Argentina and E & SE Brazil (Bahia to Rio Grande do Sul, and including Mato Grosso); presumably this race in NE Brazil (Alagoas).
