Overall COI distance summary at different taxonomic levels.

1Four species had only one sequence and so were not included in the within-species comparisons.The minimum, mean (with standard error [SE]), and maximum pairwise COI sequence distance found among individuals within species, among individuals belonging to different species within genera, among genera within families, among families within orders, and among orders within the class for all specimens of Branchiopoda from Churchill analyzed in the present study that yielded sequences >350 bp.
