The copper-throated sunbirds are within the Nectariniidae family, a grouping of sunbirds and spiderhunters. These birds are known for their nectarivorous diets, downward-curved beaks and colorful plumage. The copper-throated sunbird is within the small genus Leptocoma, which contains only 6 extant species. Leptocoma originates from the ancient Greek words leptos which means delicate or refined; and komē which means hair. In addition, the species name calcostetha originates from the words khalkos which means bronze; and stēthos which means breast. Sunbird species can be found in Africa, Asia and Australia. The current consensus is that sunbirds originated and speciated within Asia, and then spread to other continents over time.
