FIGURE 21: Maximum Likelihood phylogram of surveyed populations of the Trachymyrmex species occurring in the United States, with branch lengths, calculated under GTR+R model. Numbers on branches represent bootstrap values based on 560 pseudoreplications. The scale bar depicts expected rate of substitutions per site. County/Parish, State and Country names (for Mexican samples) are given behind the species name. Note: the taxon sampling for the genus Trachymyrmex is incomplete, thus two species appearing adjacently in this phylogram are not necessarily sister taxa.
