Maximum likelihood phylogenetic tree topology inferred from the concatenated dataset (18S rDNA, ITS-1, 28S rDNA and COI). Numbers at nodes indicate support values (posterior probability/bootstrap). *: Bootstrap value not applicable to this node, because of different topologies of trees generated by BI and ML methods.
