Subspecies
Genus probably constitutes an old Guianan and central Brazilian element with close morphological and behavioural affinities with Leucochloris and Leucippus. In past, genus was considered monospecific, comprising present species only. Forms a superspecies with Tepui Goldenthroat (Polytmus milleri). Name andinus was thought to be preoccupied and this taxon was thus renamed "doctus", but renaming unjustified.
The following 3 subspecies are recognised:
andinus Simon, 1921 - Eastern Colombia (south to Meta and Vichada).
guainumbi (Pallas, 1764) - Venezuela and Trinidad to the Guianas and northern Brazil.
thaumantias (Linnaeus, 1766) - Eastern Bolivia, eastern Paraguay and central and eastern Brazil (southern Maranhío and Bahia to Mato Grosso do Sul, Sío Paulo and northern Paraná) to north-eastern Argentina.
