Abstract. We examined morphometric variation in green toads of the genus Bufotes using univariate and multivariate statistics in order to identify diagnostic characters. This study describes patterns of variation in two diploid (B. sitibundus and B. perrini) and a tetraploid (B. pewzowi) species and triploid hybrids of B. perrini and B. pewzowi distributed in Kazakhstan and Kyrgyzstan (14 localities). Since body proportion characters were highly correlated, we divided them into each other and obtained 190 indices.
