Fish Petroleuciscus Cyprinidae freshwater fish new species Iran


A new species, Petroleuciscus esfahani, is described from central Iran in the Zayandeh River basin. It is distinguished from other members of the genus by a combination of characters including a mode of 8 1/2 dorsal-fin branched rays, modally 10-11 1/2 anal-fin branched rays, small scales numbering 44-54 in the total pored lateral line, a modal pharyngeal-tooth formula 2.5-4.2, and total vertebrae usually 40-42. It appears to be morphologically closest to Petroleuciscus gaderanus (Gunther, 1899) that we tentatively consider as a synonym of P. ulanus (Gunther, 1899) of the Lake Orumiyeh basin in northwestern Iran.
