Phyllastrephus is a songbird genus in the bulbul family Pycnonotidae. Most of the species in the genus are typical greenbuls, though two are brownbuls, and one is a leaflove.
The genus Phyllastrephus was introduced by the English naturalist William John Swainson in 1832 with Le Jaboteur (Levaillant), now the terrestrial brownbul, as the type species.[1][2] The genus name combines the Ancient Greek phullon meaning "leaf" with strephō meaning "to toss" or "to turn".[3]
Several species from Madagascar that were formerly placed in the genus Phyllastrephus have now been moved into Bernieria and Xanthomixis. Commonly called the Bernieria and the tetrakas, these species are not bulbuls but Malagasy warblers similar to greenbuls due to convergent evolution. Formerly, some authorities also considered the following species (or subspecies) as species within the genus Phyllastrephus:
