Figure 3 in Evolutionary relationships of euthyneuran gastropods (Mollusca): a cladistic re-evaluation of morphological characters
Figure 3. Proposition of a phylogeny of Heterobranchia. Here well supported nodes according to present results and character discussions are shown only. Interrupted lines indicate possible phylogenetic relationships. Unambiguous synapomorphies supporting the phylogenetic relationships of euthyneuran taxa are shown by character numbers such as listed in the text. The character numbers in italics are potentially important but require further analysis and discussion (see phylogenetic and taxonomic results).
