Subspecies
No subspecies.
A member of a species group that contains also Corsican Nuthatch (Sitta whiteheadi), Algerian Nuthatch (Sitta ledanti), Krueper's Nuthatch (Sitta krueperi), Snowy-browed Nuthatch (Sitta villosa) and Yunnan Nuthatch (Sitta yunnanensis), and all sometimes thought to form a superspecies. Formerly treated as conspecific with Corsican Nuthatch (Sitta whiteheadi) and Snowy-browed Nuthatch (Sitta villosa). Close relationship with these two supported by recent data on mitochondrial DNA, which indicate that all three form a sister-clade to Krueper's Nuthatch (Sitta krueperi) and Algerian Nuthatch (Sitta ledanti) (no Yunnan Nuthatch (Sitta yunnanensis) material was available for analysis), with a genetic distance of approximately 10% between the two clades.
