FIGURE 2. Results of the multivariate statistical analyses (ellipses always represent 95% confidence intervals). Top left: Scatterplot of the first two PC of an analysis grouping specimens into color patterns types I (solid dots), II (Xs), and III (open dots). Top right: Scatterplot of the first two PC of an analysis including specimens of A. snethlageae (open dots) and A. touzeti (solid dots). Bottom left: scatterplot of TL vs. PC2 in specimens of A. snethlageae (open dots) and A. touzeti (solid dots); fitted straight line and squared correlation coefficient are for the first species. Bottom right: Scatterplot of the first two PC of an analysis including specimens of A. badius (solid dots), A. flammigerus (Xs), and A. snethlageae (open dots).
