Subspecies
Forms a superspecies with Livingstone's Turaco (Tauraco livingstonii), Schalow's Turaco (Tauraco schalowi), Knysna Turaco (Tauraco corythaix), Guinea Turaco (Tauraco persa) and Fischer's Turaco (Tauraco fischeri), a complex of allopatric forms formerly treated variably either as a single polytypic species or as three, five or six species. Two additional localized forms (sharpei and finschi) described, but doubtfully valid, owing to much intergradation with emini and nominate schuetti.
The following 2 subspecies are recognised:
emini Reichenow, 1893 - Southern Sudan, eastern Zaire, Uganda and western Kenya to north-western Tanzania, Burundi and Rwanda.
schuettii (Cabanis, 1879) - Democratic Republic of the Congo east to the Ituri Basin and south to northern Angola.
