Subspecies
Forms a superspecies with Andaman Woodpecker (Dryocopus hodgei), and sometimes considered conspecific. Proposed subspecies buettikoferi (Nias I) appears indistinguishable from nominate; esthloterus (northern Luzon, in Philippines), supposedly with thinner bill and less white on head, is not safely separable from confusus. Subspecies philippinensis frequently misspelt "philippensis".
The following 15 subspecies are recognised:
hodgsonii (Jerdon, 1840) - Peninsular India in western Ghats, southern Madhya Pradesh, and Orissa to northern Andhra Pradesh.
forresti Rothschild, 1922 - Montane northern Myanmar and adjacent south-western China (south-western Sichuan, north-western and southern Yunnan).
richardsi Tristram, 1879 - Korea; extinct on Tsushima I (Japan).
feddeni (Blyth, 1863) - Myanmar (except north), most of Thailand, and Indochina.
javensis Tristan, 1879 - Southern Thailand south to Sumatra and Nias I, Java, Bali, and Borneo and associated islands, including northern Natunas.
parvus (Richmond, 1902) - Simeulue I (off north-western Sumatra).
