Race melanorrhoa long considered a separate species, presumably on basis of its sooty-black vent (no other notable character), but intergrades with isaurae along border of Costa Rica with Panama; isaurae was also treated as a separate species. Geographically isolated race intermedia often placed in C. buffonii, but its largely pinkish mandible supports treatment in present species; nevertheless, it may be better considered a separate species, as also suggested earlier#R; it possesses a deep metallic blue vs bronzy-green tail (3) and dull but glittering turquoise-blue vs green belly (2), and its elevational range is “mostly 500–1750 m”#R while other subspecies are in the lowlands, but elevation in N Peru given as “up to 800 m”#R; more study required. Proposed race incognita (E Panama) probably best treated as a synonym of isaurae. Four subspecies recognized.
