Related to Red-vented Barbet (Psilopogon lagrandieri), but not very closely. Subspecies weakly to moderately marked. Indochinese birds, described as subspecies indochinensis, now considered indistinguishable from nominate. Birds of Mishmi Hills (north-eastern Assam) formerly recognized as subspecies mayri, but inseparable from clamator.
