>>I think you should look carefully at the tree and think about what sharing a common ancestor means. You might notice that in the phylogeny, Charina forms a monophyletic group. Therefore all Charina share a recent common ancestor, not shared by Eryx. For your statement above to be true, Charina would have to be paraphyletic, which is not what is shown in the tree.>>
What a tree can show often depends on how many samples are included in constructing that tree. So far no one has included multiple samples of both C. bottae and L. trivirgata in a single analysis of their mtDNA. When that is done, it will probably be shown that L. trivirgata is nested within C. bottae.
