Subspecies
Some authors include present species in a superspecies with Chestnut-bellied Partridge (Arborophila javanica) and Grey-breasted Partridge (Arborophila orientalis), and all three are sometimes considered conspecific. Others attribute morphological similarities to convergent evolution. Sometimes Sichuan Partridge (Arborophila rufipectus) or Red-breasted Partridge (Arborophila hyperythra), or both, also included in the superspecies. Birds of Guangxi (central-southern China) probably belong to subspecies henrici, but sometimes ascribed to nominate subspecies.
The following 3 subspecies are recognised:
brunneopectus (Blyth, 1855) - Central-southern China (south-western Yunnan) through eastern Burma and northern Laos to western Thailand.
henrici (Oustalet, 1896) - Northern and central Vietnam; probably also central-southern China (Guangxi).
