FIGURE 4. Principal components analysis of 10 morphometric and eight meristic characters comparing G. omarorum (red) and G. cuia (blue). A. Principal component one explains 33.1% of the variance and PC2 explains 15.5% of the variance in the comparison between G. omarorum (n=12) and G. cuia (n=56). Note the separation in shapespace between species. B. Principal component one explains 41.4% of the variance and PC2 explains 27.1% of the variance in the comparison between G. omarorum (n=12) and G. cuia (n=45). Note the relatively large separation in shapespace between species.
