Races have sometimes been divided into as many as four species, but geographical variation complex, and some intergradation occurs between adjacent forms#R. Race papillosus previously referred to as damarensis, but former name has priority. More than 30 races described: traditional races marchei, callewaerti and blancoui now included in galeatus, as also are strasseni and bannermani (last two names assigned to stock introduced to Cape Verde Is); major, inermis, omoensis, macroceras, neumanni, toruensis, intermedius and uhehensis included in meleagris; ansorgei included in reichenowi; maximus, frommi, rikwae and bodalyae included in marungensis; mulondensis included in papillosus; and transvaalensis and limpopoensis included in coronatus. In E South Africa hybridization between local race coronatus and introduced domestic individuals (derived from W African subspecies galeatus) appears to exist, leading to potential outbreeding depression in wild population. Nine subspecies currently recognized.
Introduced to many parts of world, e.g. Cape Verde Is (galeatus), Yemen (galeatus), SW Arabia, Madagascar, Rodrigues I and the Comoro Is (mitratus), Western Cape (coronatus), also West Indies, apparently (sabyi) on Barbuda and parts of Australasia.
