Table 3. Features of the DNA datasets used in this study, based on one of the most parsimonious trees from the combined parsimony analysis and nucleotide substitution models selected for Bayesian analyses. (bp = base pairs; CI = consistency index; RI = retention index; Best-fit model for the Bayesian analysis was selected by AIC in MrModeltest 2.3).| DNA region | N | Aligned length (bp) | Number variable sites | Number Potentially parsimony informative sites | Number of changes/ variable sites | Fitch tree length | CI | RI | Best-fit model |
