Subspecies
Black-eared Ground-thrush (Geokichla camaronensis) and Kibale Ground-thrush (Zoothera kibalensis) (Sibley and Monroe 1990, 1993), the latter also recognised as a species (but placed in the genus Turdus) by Collar and Andrew (1988), are lumped into Zoothera camaronensis following Dowsett and Forbes-Watson (1993).
Subspecies kibalensis has been considered a separate species on basis of its higher-elevation habitat (also reportedly larger size, more rufous upperparts, more compressed bill), but graueri inhabits similar forest types at only slightly lower altitudes. Subspecies graueri has been thought by various authors to be closely related to subspecies batesi of Grey Ground-thrush (Geokichla princei), to which it is very similar in plumage.
The following 3 subspecies are recognised:
camaronensis (Sharpe, 1905) - Cameroon and northern Gabon.
graueri Sassi, 1914 - North-eastern DRCongo and western Uganda.
kibalensis (Prigogine, 1978) - Kibale Forest, in western Uganda. Considered by some authors to be a distinct species, Kibale Ground-thrush (Zoothera kibalensis).
