Subspecies
In past, sometimes placed in genus Sphenurus. Closely allied to White-bellied Green-pigeon (Treron sieboldii) and Taiwan Green-pigeon (Treron formosae), and more distantly to Sumatran Green-pigeon (Treron oxyurus) species-group. Subspecies korthalsi formerly considered a distinct species on basis of emarginated third primary, but this feature subsequently found in some birds of other subspecies in present species.
Proposed subspecies yunnanensis and oblitus included in nominate; annamensis in robinsoni; and etorques in korthalsi.
The following 5 subspecies are recognised:
