Phylogenetic relationships within Tetraconata. (a) Inferred by PhyloBayes CAT-GTR with matrix 4 (455 decisive genes). All nodes within Malacostraca and Branchiopoda were collapsed (for details, see the electronic supplementary material, table S2 and figures S2 and S3). Support values for all analyses are depicted as rug plots, with each cell representing a specific combination of matrix and analytical method. Nodes supported in only one of two PhyloBayes chains are marked in yellow (the two PhyloBayes chains did not converge for these nodes). Individuals newly sequenced for this study are highlighted in bold. (b–k) All alternative topologies recovered in any analysis with support greater than 50 or 0.5. Alternative relationships within allotriocaridan and multicrustacean taxa (b–k), within Oligostraca (g–h), within Thecostraca (i) and Hexapoda (j–k) are depicted. (Online version in colour.)
