F.] 1877: 137; Type locality: Kura River, Tbilisi , Georgia , Eurasia. Syntypes : (8) BMNH 1897.7.5.27 [ex St. Petersberg Univ.] (1), ZIN 10919 (2). Common name : Pr: Shekamsiah-e Aras, En: Southern Caspian nase. Diagnosis : This species is the only one in its genus in the Caspian Sea basin. Meristic characters : D: IV 8–10, A: III 9–10, P: 9–15, V: 9–10, GR: 21–31, LL: 55–64, TV: 43–45. Distribution : Caspian Sea basin ( Fig. 242 ). Only found in upper part of Aras River ( Jouladeh-Roudbar et al. 2015c ). Taxonomy . Conservation : IUCN: Not Evaluated, PC: Data Deficient. This species occurs in Kura and Aras River systems which are shared between Iran , Armenia , Turkey and Azerbaijan . In Iran a very reduced number have been recorded from one locality (Aras dam, Close to Poldasht county), but there is no information about it from the other countries where it occurs. Hence, we did not believe that there are enough data to make a classification. Fig. 240. Distribution map of Blicca bjoerkna . Fig. 241. Chondrostoma cyri .

Meristic characters : D: IV 8–9 (8), A: III 10, P: 15–17, V: 9, GR: 15–17, LL: 51–58, TV: 43. Distribution : Tigris basin ( Fig. 244 ). Just found in Sarab-e Ravansar River ( Eagderi et al. 2017a ). Taxonomy . Conservation : IUCN: Not Evaluated, PC: Vulnerable D 2 . This species is only found from Sarab e Ravansar ( type locality), situated in Ravansar city center and is severely affected by water extraction, pollution and drought. Area of occupancy of the species is typically less than 20 km 2 ; we therefore classified it as Vulnerable D 2 .
