Meristic characters : D: II 6, A: II 5, P: 7–8, V: 5–6, Z4: 12–17, TV: 39–40. Distribution : Tigris basin ( Fig. 284 ). Found in Gamasiab, Dinevar and Leyleh Rivers. Taxonomy . Conservation : IUCN: Not Evaluated, PC: Endangered B2ab(i,ii,iii,iv). Populations of this species are only known from three localities which occur in highly reduced numbers. This species is critically affected by severe drought, water extraction for agricultural use, pollution, loss of habitat due to gravel extraction from the river beds and isolation of local populations. It occurs in less than five localities and its AOO is less than 500 km 2 and severely fragmented. Therefore, we classified it as Endangered.
