Seven-colored Tanager is classified in the genus Tangara, the largest genus of Neotropical birds. Tangara is divided into 13 species groups based on vocalizations, diet, geographic distributions, behavior, and appearance (Isler and Isler 1987). Traditionally, plumage has been key indicator of the relationship of Seven-colored Tanager to other species of Tangara. Based on plumage similarities, Isler and Isler (1987) grouped Seven-colored Tanager in species group 3, with T. seledon (Green-headed Tanager) and T. chilensis (Paradise Tanager) (Isler and Isler 1987). Recent phylogenetic analysis, however, does not show that all three of these species are closely related. Seven-colored Tanager is the sister taxon to Green-headed Tanager, but Paradise Tanager is not closely related (Burns and Naoki 2004, Sedano and Burns 2010, Burns et al. 2014). Both Seven-colored and Green-headed tanagers belong to a clade that also includes T. desmaresti (Brassy-breasted Tanager), T. cyanocephala (Red-necked Tanager), and T. cyanoventris (Gild-edged Tanager). All five of these species are found in the Atlantic Forest; thus, all of these species likely descended from an ancestor that also lived in the Atlantic Forest, and their speciation is not the result of repeated colonization to the area (Sedano and Burns 2010).
