Figure 3. Principal component analysis of Mesobuthus eupeus and Mesobuthus caucasicus based on morphological ratios. (A) and (B) plot positions of the species, respectively, with respect to the first and second components and with respect to the first and third components (see text). Mesobuthus eupeus and M. caucasicus are encircled according to species identification in phylogenetic tree shown in Figure 2:, M. eupeus;, M. caucasicus.
