FIGURE 9. Genealogical network for the control region haplotypes observed within the clades of Uca crassipes (White, 1947) (collected from the Ryukyus, Taiwan, the Philippines, Guam, Indonesia, Cocos-Keeling, New Caledonia and Polynesia) and U. boninensis sp. nov.

Probability values at the nodes represent support values for ME, maximum parsimony (MP) and maximum likelihood (ML). For haplotype names, see Table 1. "*" means the haplotype is heteroplasmic obtained by cloning.
