J. F. Gmelin, 1788,
Type locality erroneous, since species has never occurred on Tahiti#R. Traditionally thought to form a species-group with several other Australasian and Polynesian species (see T. sanctus). Taxonomy of this group uncertain, and species boundaries not clear. Usually includes T. ruficollaris. Extinct nominate race of T. gambieri sometimes placed within present species on basis of morphological criteria, but current limited information suggests that it is probably better combined with the other Tuamotu taxon, gertrudae, in a separate species. Races pealei, manuae, marinus and sacer of T. chloris may belong in present species. Detailed genetic research required in order to clarify these taxonomic problems, but this is hampered by scattered distribution of the various populations over thousands of kilometres of Pacific Ocean. Specific name often given as tuta, but is Latinized Greek adjective and must agree with masculine genus name. Three subspecies currently recognized.
