Holotype: NHMG 5021.[1]

Geographic range

Known only from the Çoruh River valley in Artvin Province, northeastern Turkey. It is probably also found in the Turkish province of Erzurum, as well as the Kura valley in Georgia.[1] Mallow et al. (2003) describe the range as Turkish Anatolia and adjacent parts of Georgia.[2] The type locality is "Coruh valley, province Artvin, northeastern Turkey.[1]

Conservation status

This species is classified as Critically Endangered (CR) according to the IUCN Red List of Threatened Species with the following criteria: C2ab, D (v2.3, 1994).[4] This indicates that the total population is estimated to number less than 250 mature individuals. A continuing decline has been observed, projected, or inferred in numbers of mature individuals. It is unclear whether the population structure is either severely fragmented (i.e. no subpopulation estimated to contain more than 50 mature individuals), or that all individuals are in a single subpopulation. In case of the latter, the total population may number less than 50 mature individuals. Year assessed: 1996.[5]It is also listed as a strictly protected species (Appendix II) under the Berne Convention.[6]

Habitat

Found on steep wooded mountain slopes with rock outcroppings and piles of stones.[1]
