Subspecies
Genus sometimes merged into Picoides. Relationships within genus somewhat obscure and most likely related to southern Asian Fulvous-breasted Woodpecker (Dendrocopos macei) superspecies and Scarlet-breasted Woodpecker (Dryobates cathpharius). Variation, particularly in tone of underparts, is considerable, but largely individual.
The following 4 subspecies are recognised:
marshalli (Hartert, 1912) - North-eastern Pakistan, Kashmir and northern India.
hyperythrus (Vigors, 1831) - Nepal east to south-eastern Tibet and western and south-western China (Sichuan, Yunnan), south to Bangladesh, central Myanmar and north-western Thailand.
annamensis (Kloss, 1925) - Eastern Thailand, Cambodia and southern Vietnam.
