TABLE 1. Morphometric variables compared between C. ectopistes sp. nov. and C. robustus s.s., including mean (x) and standard deviations (s), test statistics (either Wilcoxon rank-sum test, W, or Welch’s t -test, t, with subscript = degrees of freedom), and associated p -values. Statistically significant differences between the two species (P <0.05) are denoted using an asterisk *. Length (L), width (W), depth (D), total carapace length (TCL), carapace width (CW).
