Spalax is a genus of rodent in the family Spalacidae, subfamily Spalacinae (blind mole-rats). It is one of two extant genera in the subfamily Spalacinae, alongside Nannospalax.
Species in this genus are found in Eastern Europe and Western & Central Asia. They are completely blind and have a subterranean lifestyle.
Taxonomy
Prior to 2013, Spalax was widely considered the only member of Spalacinae, with all blind mole-rat species being grouped within it. However, phylogenetic and morphological evidence supported some of the species within it forming a distinct lineage that diverged from the others during the Late Miocene, when a marine barrier formed between Anatolia and the Balkans. These species were reclassified into the genus Nannospalax, making Spalax one of two extant spalacine genera.
