Forms a superspecies, and conceivably conspecific, with Gabela Helmetshrike (Prionops gabela). Other proposed subspecies are intermedius (described from Mwanza, south of L Victoria, in Tanzania), synonymized with tricolor, and neumanni (from Fanole, in Somalia), synonymized with graculinus.
The following 4 subspecies are recognised:

graculinus Cabanis, 1868 - Southern Somalia, Kenya and north-eastern Tanzania.
retzii Wahlberg, 1856 - Extreme southern Angola (southern Huíla and probably Cubango) and southern Zambia south to northern Namibia, northern and eastern Botswana, Zimbabwe and northern South Africa.
tricolor Gray, GR, 1864 - Western and southern Tanzania and southern and eastern Zambia south to Malawi, Mozambique, north-eastern South Africa and eastern Swaziland.
