Subspecies
No subspecies.
Genus as currently constituted probably polyphyletic. In-depth analysis of morphology, voice, behaviour and genetics required to redefine its limits. Present species previously placed, along with Black-crested Bulbul (Pycnonotus flaviventris), Flame-throated Bulbul (Pycnonotus gularis), Black-capped Bulbul (Pycnonotus melanicterus) and Bornean Bulbul (Pycnonotus montis), in a separate genus Rubigula, to which all five may yet be returned. They form a superspecies, and have often been treated as conspecific under the name "Pycnonotus melanicterus".
Considered by some authors to be a subspecies of Black-crested Bulbul (Pycnonotus flaviventris).
