Sometimes placed in separate genus Chrysotrogon. DNA studies suggest possibly closest to T. viridis (with T. chionurus) and T. curucui, recent work#R indicating paraphyly, leading to proposed split of races caligatus (with sallaei and concinnus) and ramonianus (with crissalis) as two separate species#R, an arrangement practised in the past. Nevertheless, independent confirmation of this circumstance is needed, since plumage characters overlap extensively, rendering diagnosis problematic; moreover, despite remark that caligatus and violaceus have “strikingly different songs”#R, evidence online suggests that vocalizations in this complex are shared by taxa supposedly belonging to different species. N race commonly labelled as braccatus, but name sallaei has priority#R. Extensive individual variation in degree of bronzy tinge on back in nominate and race caligatus led to description of rossi, now considered a synonym of nominate. Six subspecies recognized.
