Type, Alsocomus puniceus Tickell.
The present genus is often included in the genus Columba, from which, however, it differs so extremely in colour that it seems desirable to keep it apart. Wings, taxi and bill are as Columba but it has no neck-patch as in some of the species of that genus nor has it the strong gloss on the neck present in those species which have no wing-patch. Prom Ianthaenas it differs in having no naked space through the lores.
