Close to T. lavinia; replaced by latter in wet Chocó–Pacific lowlands. Races appear to form three plumage groups: “albertinae group”, with blue underparts and rump (in W & S); “viridissima group”, with green underparts and rump (in N); and single-taxon “gyrola group”, with mixed underparts and green rump (in E & SE); these have in the past been treated as three separate species, but geographical pattern of character distribution renders such an arrangement problematic, and calls appear similar across range; further study desirable. Name “gyroloides”, dating to 1847, was in the past applied variously to birds of races deleticia, albertinae and catharinae; however, it is a replacement name for the preoccupied “Aglaïa Peruviana”, which is itself unidentifiable owing to contradictory features in the description. Nine subspecies recognized.
