Evolutionary relationships between Tapinoma atriceps and Tapinoma breviscapum A bayesian phylogenetic reconstruction based on concatenated sequences of four molecular markers (COI, LWRh, WG, and EPIC). The scale bar represents substitutions per site and the number next to nodes the posterior probability B haplotype network including several populations of T. atriceps and a single sample of T. breviscapum (H08). Every circle represents a different haplotype, the color corresponds to the geographical distribution, and the number between brackets corresponds to the number of mismatches between haplotypes.
