Previously placed in monotypic genus Spizastur, and thought to be very similar to Old World Hieraaetus; recent phylogenetic study, however, found that this taxon was nested among the New World Spizaetus group#R. DNA studies indicate that this species is sister to the pair S. ornatus and S. isidori#R#R#R. Monotypic.

Distribution:

E & S Mexico (S Tamaulipas, Oaxaca) S through Central America to Colombia, E Peru and N & E Bolivia to Paraguay, N Argentina (Jujuy, Salta, Tucumán, Misiones) and S Brazil, and E through Venezuela to the Guianas, then S to C Brazil.
