 * Grey-olive Greenbul, Phyllastrephus cerviniventris
 * Pale-olive Greenbul, Phyllastrephus fulviventris
 * Baumann's Olive-Greenbul, Phyllastrephus baumanni
 * Toro Olive Greenbul, Phyllastrephus hypochloris

Several species from Madagascar that were formerly placed here are now separated in Bernieria and Xanthomixis. Commonly called the Bernieria and the tetrakas, they are not bulbuls but Malagasy warblers similar to greenbuls due to convergent evolution.
