This species has only just been described – Creme-eyed Bulbul (Pycnonotus pseudosimplex Shakya et al.); it is one of the many cryptic species that have been previously overlooked.
The species appears to be more closely related to the Gray-fronted Bulbul (Pycnonotus cinereifrons(Tweeddale)) from the island of Palawan, Philippines than to the White-eyed Bulbul (Pycnonotus simplexLesson) with which it shares its habitat on the Indonesian island of Borneo and which it closely resembles.
