Sometimes placed in genus Dysithamnus. Closely related to T. saturninus and has been treated as conspecific; taxonomic study of populations needed. Races appear to intergrade; specimens in N part of range of nominate approach obidensis in extent of black on male throat, and region in E Colombia that is said to separate races is poorly known ornithologically; further work required. Two subspecies recognized.

Subspecies and Distribution
