Until recently included T. assimilis as a subspecies group. Race daguae has been given separate species status#R#R or assigned to T. assimilis, but on vocal evidence#R and rufous-tinted upperpart coloration belongs with present species. S races contemptus, paraguayensis, crotopezus and nominate differ in their irregularly dull-orange-washed flanks and slightly grey-tinged crown, but are equally weakly differentiated in voice. Eight subspecies currently recognized.
