Trees inferred from the Bayesian analysis (a) and from the maximum parsimony analysis (b) of nucleotide sequences of 13 single-copy genes. Branch lengths are proportional to the number of expected nucleotide substitutions; scale bar corresponds to one substitution per ten sites for the Bayesian tree and to 100 changes for maximum parsimony tree. Posterior probability and bootstrap values (greater than 0.5 and 50% respectively) are indicated by the colored bars placed on branches.
