Fig. 9. Cladistic analysis of pholadoidean bivalve Barnea (Anchomasa) Leach, 1852 obtained by processing the matrix in Appendix 4. Exhaustive search with constraints enforcing the relationships among the outgroup taxa in order to reproduce the distribution of the supraspecific characters and the topology of the cladogram in Fig. 3. Strict consensus of three most parsimonious cladograms (L 21, CI 0.62, RI 0.74, RC 0.46). Unsupported nodes collapsed. See text for the definition of the cladistic parameters. Symbols as in Fig. 3.

Fig. 3 in Phylogeny and biogeography of pholadid bivalve Barnea (Anchomasa) with considerations on the phylogeny of Pholadoidea

Fig. 3. Phylogeny of Pholadoidea. Most parsimonious tree corresponding to the 50% Majority Rule consensus tree obtained by successive approximation weighting. L 96. Indices under unitary weight conditions: CI 0.54, RI 0.85, RC 0.46. Indices under reweight conditions: CI 0.78, RI 0.94, RC 0.74. Abbreviations: L, length; CI, consistency index; RI, retention index; RC, rescaled consistency index. Numbers in bold indicate the Majority Rule values and, in brackets, the bootstrap support values of the individual nodes. Only bootstrap values higher than 40% are shown. Numbers in smaller type represent the most significant state changes at the respective nodes. Exclusive synapomorphies are in bold. Unambiguous not−exclusive synapomorphies are in normal type. Abbreviations A and D mark the ambiguous changes of character states under ACCTRAN and DELTRAN optimisations, respectively. For changes of character states in the Pholadinae clade see Fig. 4. The classification of Pholadoidea in Turner (1969) is shown besides the tree by comparison.
