Nilson and Andrén (1986) restricted the species to "Xanthos" [= Xanthus] (Kinik) province Mugla, S. W. Turkish Anatolia" through lectotype designation.

Conservation status

This species is classified as Least Concern (LC) according to the IUCN Red List of Threatened Species (v3.1, 2001). Listed as such due to its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. Year assessed: 2005.

It is, however, listed as strictly protected (Appendix II) under the Berne Convention.

Taxonomy

According to Nilson, Andrén and Flärdh (1990), V. bornmuelleri, V. bulgardaghica, V.wagneri and V. xanthina are all closely related and together form the Vipera xanthina group or complex.
