We explored the population systems of Pelophylax bedriagae (Camerano, 1882) in northwestern, western and southwestern Iran. Statistical significance for a hypothesis of sexual dimorphism of the frogs was tested using t-test and multivariate analysis of variances (MANOVA). Due to lack of sexual differences between the male and female frogs, the data of both sexes were pooled for further analysis. Taxonomic relationships among local populations were investigated using discriminate analysis (by stepwise method) with iterative sample assignment. The multivariate morphometric analyses revealed that the range of P. bedriagae extends to western Iran. The next step was to analyze the advertisement call (five standard parameters: call duration, number of pulse groups per call, duration of pulse groups, interval between pulse groups, and intercall interval) of the water frogs inhabiting three sites in western Iran. Rigorous application of the bioacoustic method removes all doubt that these three sites are inhabited by the same species, which on the basis of priority of nomenclature should be called P. bedriagae.
