The genus Jaculusis distributed in Palearctic desert and semi-desert areas, extending from Central Asia to the Western Sahara in the North Africa. In Iran three species of three-toed Jerboa have been reported: Jaculus jaculus from the south west and west of Iran, Jaculus blanfordi from the northeast, east and central part of Iran and Jaculus thaleri from the east of Iran. In present study, the phylogenetic and taxonomic relationships in the genus Jaculus from Iran were examined using molecular, geometric morphometric and morphologic data. Our molecular analyses indicated two monophyletic clades which contain J. jaculus and J. blanfordi. There is a high amount of genetic interspecific distance (12.7%) between J. jaculus and J.blanfordi, while the intraspecific divergence within these two species is low. Analysis of Variance (ANOVA) of morphometric variables were significant (P
