Fig. 1

Maximum likelihood analysis with 10,000 bootstrap replications based on the Kimura 2-parameter model. The tree with the highest log likelihood (−1598.0929) is shown, and the tree is drawn to scale with branch lengths measured in the number of substitutions per site. The percentage of trees in which the associated taxa clustered together is shown next to the branches. There were a total of 530 positions in the final dataset
