Maximum Likelihood tree based on a 562 bp fragment of the mitochondrial COI gene from Corbicula spp. Posterior probabilities from Bayesian Inference (first) and bootstrap values from Maximum Likelihood (second) are indicated for nodes found in both analyses. Sequence of Neocorbicula limosa was used as an outgroup. See Table 1 for the origin of all the sequences. The three European morphotypes are indicated (form R, form S and form Rlc) and the frames are colour coded according to Fig. 1. Two individuals of form R exhibited the COI haplotype of form S (haplotype 2 = FW17).
