J. F. Gmelin, 1788,
Closely related to H. barroti, with which sometimes regarded as conspecific. Indeed, extent of differentiation needs reviewing: it is commonly claimed (in both texts and illustrations, e.g. HBW#R#R) that female of present species differs in having grey-spotted breast, but this character is present in both species; reported minor differences in size and bill length#R#R not obvious in unmeasured material; thus all-green vs glittering purple crown of male (3) is only obvious distinction; detailed study required, including data for voice and display. Proposed race major probably a young male of H. barroti (which see). Three subspecies recognized.
