In the past, sometimes placed in genus Sphenurus. Closely allied to T. oxyurus and T. seimundi, and these three species may form a link between the African and other Asian Treron species; more distantly related to the T. sphenurus species-group. Race lowei fairly distinctive, differing from apicauda and laotinus in its reduced or non-existent dull orange breast patch (1), brighter yellow rump (2), feathered lores (1), and slightly different structure of two primaries (difference not obvious and function unknown; score perhaps 1); vocal evidence worth checking. Distribution of lowei sometimes believed to also encompass at least parts of Thailand, but photographs from there suggest that nominate group is involved; still, further research necessary. Three subspecies recognized.
