* We considered homogeneity as significantly rejected with P- values ≤ 0.01. The pairwise deletion option was used to compare all possible species pairs (100% = all pairwise comparisons between the species from both taxa rejected homogeneity). Anomalodesmata were treated separately and thus are excluded when showing results for the remaining Heterodonta.
