Figure 4. Clade A subtree of the Bayesian tree obtained after analysis of the MCPV-4G data set. Support values are indicated for each node as Bayesian analysis Posterior probabilities values (when ≥ 0.8)/maximum likelihood bootstrap values (when ≥ 50)/ BA Posterior probabilities values for the COI single gene analysis (when ≥0.8). Voucher shells for those species studied morphologically are illustrated; numbers in bold correspond to scanning electron microscopy photos of their radulae [shown at the bottom for Volutomitridae (Microvoluta joloensis – 1), Exilioidea sp. (2), and Columbariinae (Coluzea cf. liriope – 3) and in Figure 5 for Exilia, Ceratoxancus, Latiromitra, and Costellariidae]. MCPV, Mitridae−Costellariidae−Ptychatractidae−Volutomitridae.
