In the autumn 2012, a study in order to evalute the accuracy of describe four species from Alburnoides was done using morphological characters. The samples from three speices including Alburnoidesnamaki, Alburnoidesidignensis and Alburnoidesnicolasi caught by electrofishing from type locality that reported by Bogutskaya and Coad, 2009 and also, the samples of Alburnoideseichwaldiiwas caught from SiahroodRiver.Thirty three morphometric and five meristic characters were analysed. Morphologicalcharacteristics were standardized before statistical analysis to reduce the error ofthe allometricgrowth. In order to evaluate of morphometric variation between the mentioned populations, the morphometric and meristic characters and relative morphometric were analyzed by PCA and MANOVA/CVA methods. Our results showed a high coverage of morphometric characters in the mentioned populations and approximately these populations were not in separate site. Also, due to highe coverage in these populations, this seem that the separation of three populations in gharechay, Bidsorkh and noorabad that before described by Coad and Bogutskaya (2009) as A. namaki, A. idignensisand A. nicolausiis not possible.
