APPENDIX

Raw data used for the canonical variate analysis

Measurements were made twice from scanned SEM photographs, one after discarding the magnification factor and the other with considering it. The results of the analysis were approximately the same in both cases indicating that the magnification factor was not affecting the analysis as a result of the constant ratio of the dimensions measured for each specimen. The following measurements are based on discarding the magnification.

The length of the carapace (L), the height of the carapace (H), the distance from the eye tubercle to the maximum end of the posterior margin (P), the distance from the eye tubercle to the maximum end of the ventral margin (V) and the length of the hinge (G)
