Tassonomia

This species was described by Thomas Campbell Eyton as Perdix Charltonii in 1845. The IOC World Bird List recognises the subspecies T. c. charltonii found in the Malay Peninsula, T. c. atjenensis in Sumatra. Some authorities have considered the green-legged partridge (A. chloropus) to be conspecific with this species. The Sabah partridge (T. graydoni) was also previously considered conspecific.
