Figure 2. Species tree estimated using the multispecies coalescent model in *BEAST. Specimens shaded in grey are from the Southern Hemisphere. Specimens in bold represent new species. Two support values are presented: first, the posterior probabilities from *BEAST; second, the posterior probabilities from the concatenated MRBAYES tree (see Supporting Information, Fig. S3), where '–' indicates the absence of the node in question. Scale bar shows the expected number of changes per site scaled in accordance with the substitution rate of COI.
