FIGURE 10. Maximum likelihood topology for the DNA-only dataset. The parsimony bootstrap values are shown above the branches or horizontal line; these values apply to this particular tree and do not indicate that the parsimony analysis supported these nodes most strongly. The Bayesian posterior probabilities are shown below branches. Asterisks represent bootstrap values of 100% or Bayesian posterior probabilities of 1. The dots refer to the names of the higher taxa.

FIGURE 9. Bayesian phylogenies of the combined DNA and morphology dataset (left) and the morphological dataset only (right). The parsimony bootstrap values are shown above the branches or horizontal line; these values apply to this particular tree and do not indicate that the parsimony analysis supported these nodes most strongly. The Bayesian posterior probabilities are shown below the branches or horizontal line. In the tree on the right, the polytomies were formed by collapsing those nodes with <50% posterior probability. The dots refer to the names of the higher taxa.

Fig. 9. Maximum likelihood bootstrap consensus tree of 34 Quadrulella COI sequences and 71 other hyalosphenid sequences based on a 684- nucleotide position alignment. The numbers along the branches represent respectively the bootstrap values obtained by maximum-likelihood analysis, posterior probability values obtain by Bayesian analysis and parsimony scores obtain by maximum parsimony analysis. Only values above 50/0.50/50 are shown. The tree is rooted with the Padaungiella–Alocodera group. The scale bar corresponds to the mean number of nucleotide substitutions per site on the respective branch.
