Subspecies
Sometimes placed with Velvet-fronted Nuthatch (Sitta frontalis) and Yellow-billed Nuthatch (Sitta solangiae) in a separate genus, Oenositta. They may form a superspecies and have at times been considered conspecific. Possibly more closely related to Yellow-billed Nuthatch (Sitta solangiae), Hainan subspecies chienfengensis of which may form link between the two species (both are yellow-billed, whereas Velvet-fronted Nuthatch (Sitta frontalis) has red bill). Geographical variation partly clinal, colour saturation and dominance of lilac tones in plumage increasing from north to south through islands.

The following 6 subspecies are recognised:

mesoleuca (Ogilvie-Grant, 1894) - North-western Luzon (western Cordillera mountains), in northern Philippine Is.
isarog Rand & Rabor, 1967 - Luzon (except north-west).
oenochlamys (Sharpe, 1877) - West-central Philippines (Panay, Guimaras, Negros and Cebu).
lilacea (Whitehead, J, 1897) - East-central Philippines (Samar, Biliran and Leyte).
