FIGURE 2. The highest-likelihood tree resulting from maximum-likelihood analysis of COI alignment. Ultra-fast bootstrap values are presented at nodes. Terminals are labeled with a sample ID, the morphology-based identification, and sampling locality. Clades are labeled with species identifications. Species delimitation results are indicated using + for support for the specieslevel distinctiveness of a node,—for a lack of support, x for too few individuals to conduct the analysis. They are presented in the following order: ABGD/P (randomly distinct)/Rosenberg's P (AB). SMAW=San Marcos Artesian Well.
