FIGURE 4. Maximum clade credibility tree based on Bayesian inference (BI) for Gecarcinus, Johngarthia and the outgroup, Cardisoma guanhumi, using the concatenated matrix of the 16S and COI genes. Probability values at the nodes refer to support values for BI and maximum likelihood (ML). In the assigned key for Mexican specimens, the last letter indicates the sex of the organism: male (M), female (H) or juvenile (JU), followed by the individual number. The organisms highlighted in red in the Atlantic Clade correspond to specimens from Costa Rica and Panama. See the locality list in table 1.
