Previously placed in Stactolaema, but such treatment would lead to paraphyly in latter genus#R. Races belcheri and woodwardi sometimes treated both as full species, but their features are apparent to some degree in other races, and they are vocally identical. Proposed race hylophona included within woodwardi, although tending towards N races. Five subspecies recognized.

Subspecies and Distribution
  • C. o. olivacea (Shelley, 1880) – Green Barbet – SE Kenya and NE Tanzania.
