Molecular phylogenetic analysis. The maximum-likelihood method based on the Kimura 2-parameter model was used with 100 bootstrap replicates. Branches corresponding to partitions reproduced in less than 50% bootstrap replicates are collapsed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. Evolutionary analyses were performed in megaX
