Subspecies
Little Bronze-cuckoo (Chalcites minutillus) and Green-cheeked Bronze-Cuckoo (Chrysococcyx rufomerus) (Sibley and Monroe 1990, 1993) have been lumped into Chrysococcyx minutillus following Payne (1997 and 2005).
Some authors consider this a subspecies of Little Bronze-cuckoo (Chalcites minutillus).
