Subspecies
This genus and Cyanerpes were previously regarded as members of a separate family, Coerebidae, but later placed in present family on basis of similarities in skull anatomy; molecular phylogenies indicate that the two genera are sisters and form a monophyletic group with Tersina. Often treated as conspecific with Yellow-tufted Dacnis (Dacnis egregia), but the two differ in plumage and are geographically isolated from each other. Further research is required.
The following 3 subspecies are recognised:
egregia Sclater, PL, 1855 - Northern Colombia in southern Córdoba (upper R Sinú), Antioquia (lower R Cauca and Nechí Valley), and middle and upper Magdalena Valley from Santander south to Tolima and Huila. Considered by some authors to be a distinct species, Yellow-tufted Dacnis (Dacnis egregia).
aequatorialis von Berlepsch & Taczanowski, 1884 - Western Ecuador (Esmeraldas south to El Oro). Considered by some authors to be a subspecies of Yellow-tufted Dacnis (Dacnis egregia).
lineata (Gmelin, 1789) - Northern and western Amazonia.
