J. F. Gmelin, 1788,
Sister-species of G. aeneus, and often considered conspecific but they meet in W Panama and W Colombia without interbreeding; present species interrupts former probably continuous distribution of G. aeneus and presumably in gradual process of replacing it. Several attempts made to subdivide present species into races, with affinis (of the Guianas), mazeppa (CE Brazil) and abrawayae (SE Brazil) described on basis of plumage differences in immature and adult males and females, but these did not take into consideration intraspecific variation in coloration and measurements independent of geography; only birds from Grenada, Trinidad and Tobago are morphologically separable. Includes proposed taxon Threnetes grzimeki, based on immature male plumage. Two subspecies currently recognized.
