A Bayesian phylogenetics estimates and B haplotype networks of COI and EF1-α-F1 sequences of North American Trachymyrmex species. The phylogenetics inference was calculated with COI and EF1-α-F1; clade support is indicated above branch posterior probability by Bayesian inference. Due to the incomplete taxon sampling the tree was midpoint rooted. In the minimum-spanning haplotype networks for COI and EF1-α-F1, each circle represents a haplotype, with size proportional to the haplotype’s frequency in the population. Numbers along branches represent substitutions.
