In the past was sometimes placed in genus Porphyriornis. Until recently, unclear whether present species monotypic or a subspecies of recently extinct population named †G. nesiotis of Tristan da Cunha, but molecular data suggest that, if comeri is accepted as distinct from G. chloropus, then †G. nesiotis should be treated as distinct from G. comeri#R.

Introduced to Tristan da Cunha.
