Figure 2. Bayesian phylogram for basommatophoran taxa based on 2423 nucleotide positions of combined COI and 18S rRNA sequences showing the 50% majority-rule consensuses of topologies sampled during the Bayesian search. The tree was rooted with the outgroup Acroloxus lacustris. The scale bar indicates the expected number of substitutions per site according to the model of sequence evolution applied. Posterior probabilities are provided above the branches. Note that the topology of a maximum likelihood phylogram (not presented here) is identical with the Bayesian phylogram. Maximum likelihood bootstrap support (1000 replicates) is indicated below the branches. Family assignments follow Boss (1982). Ambiguous assignments are indicated by hatchings.
