FIGURE 2. Mensural character variation between lineages based on n = 54 specimens. (A) Biplot of PCA with axes showing the first two principal components (PC1 and PC2) and their percentage of explained variation. Large, coloured ovals denote the 90% concentration ellipses for each lineage. Small points denote PC scores of individuals, whereas large points denote group centroids. Holotype specimens are denoted by 'H' above data points. Variables are denoted by arrows, the direction and length of which indicates their degree of contribution to each axis. Each variable is coloured according to its percentage contribution to its associated PC. (B) Graph of mensural character loadings from PCA. (C) Violin plots with embedded boxplots of size corrected mensural characters for each lineage showing the mean (white dot), range, frequency, and inter-quartile range (black rectangle). Asterisks denote characters bearing statistically significant mean differences. Note that SVL was not included in the PCA of size adjusted characters, but is presented in C to show raw adult (> 75 mm SVL) variation in SVL (n = 62 for SVL in C).
