Both populations are confined to well-defined distribution areas. While both populations are separated in the south by Mt Suphan, an extinct volcano over 4000 m high, there is no geographic barrier between both populations in the north, and there seems to be a secondary contact zone. The Van population constitutes a new chromosomal form of Mole Rat in Turkey, and could be regarded as a sibling species. However, no taxomomic decision is taken until more evidence on the evolution of these forms has become available.eninfo:eu-repo/semantics/closedAccessRodentiaSpalacidaeNannospalax NehringiKaryotypeTurkeyArticle481724WOS:000271755400003N/A
