Subspecies
May form a superspecies with Yellow-scarfed Tanager (Iridosornis reinhardti), and sometimes considered conspecific, although there are significant morphological differences. Subspecies caeruleoventris may be a separate species. Conversely, ignicapillus and subsimilis differ little from nominate and possibly better synonymized with latter.
The following 4 subspecies are recognised:
caeruleoventris Chapman, 1915 - Northern end of western Andes (Paramillo) and northern part of central Andes (Antioquia south to Tolima), in north-western Colombia.
ignicapillus Chapman, 1915 - South-western Colombia (spottily at southern end of western and central Andes).
subsimilis Zimmer, JT, 1944 - Western slope of Andes in Ecuador (south to upper Chiriboga road, in Pichincha).
rufivertex (Lafresnaye, 1842) - Andes of south-western Venezuela (southern Táchira), both slopes of adjacent eastern Andes of Colombia (south to Cundinamarca and on eastern slope in Nariño), and entire eastern slope of Andes in Ecuador south to northern Peru (near Piura-Cajamarca border and north of Marañón Valley).
