A total 68 specimens of <br /> <em>A. marmid </em>from the Gamasiab River, Tigris river drainage, 85 specimens of <em>A. microlepis </em>from the Arasand Sefid rivers, Caspian Sea basin, and 90 specimens of <em>A. urmianus </em>from Mahabad-Chai and Godar-Chai rivers, Lake Urmia basin were captured by beach seine and electrofishing device. After anesthesia, the collected specimens were fixed into 10% buffered formalin and were transferred to the laboratory for further studies. Six meristic and 16 morphometric characters were counted and measured. The results showed a significant difference between the studied species in all morphometric traits except the pectoral fin length (P<0.05). In the cluster analysis, <em>A. microlepis </em>and <em>A. urmianus</em> were positioned in a clade. A significant difference found between the studied species in terms of the  meristic traits, including the lateral line scales, dorsal-fin unbranched and branched rays, and Anal-fin branched rays (P<0.05). MANOVA/CVA indicated that <em>A. urmianus</em> differed from <em>A. microlepis</em> in terms of the meristic traits. Also <em>A. microlepis</em> was positioned in a clade based on the result of meristic traits cluster analysis.
