Taxonomy.

Conservation: IUCN: Not Evaluated, PC: Critically Endangered B2ab(i,ii,iii,iv). A single population of this species is found in the Norabad River (type locality). Other reports of this species in other parts of the Tigris basin are mis-identifications of A. idignensis . The habitat of this species is heavily influenced by the unregulated exploitation of water resources for agricultural fields, furthermore during cultivation season pesticides are widely introduced into the habitat of this species. This species just found in single locality and we estimated EOO of less than 100 km 2 and AOO of less than 10 km 2. We therefore classified it as Critically Endangered.
