FIGURE 10 | Bayesian GMYC tree of a 591 bp alignment of the mitochondrial COI (cytochrome C oxidase subunit 1 gene) marker. Color boxes indicate taxonomic assignments found through all species delimitation analyses; lineages without color were not recovered on all analyses. Number on nodes corresponds to posterior probabilities (PP). GMYC = General mixed Yule coalescent method; bPTP = Bayesian implementation of the poisson tree processes; ABGD = Automatic Barcode Gap Discovery.
