Phylogenetic relationship of 31 representative Scylla specimens from Samutprakarn and Samutsongkram provinces of Thailand. A neighbor-joining tree was constructed using mitochondrial 16 S rDNA sequences of reference S. serrata, S. paramamosain, S. tranquebarica and S. olivacea, and 31 recent Scylla species collected from Samutprakarn and Samutsongkram provinces of Thailand. Yellow highlights indicate crabs with at least 1 nt difference compared with those of the respective reference species. The value at each node is the percent bootstrap confidence calculated from 1000 bootstrap resamplings. Bootstrap values of 50% and below have been omitted in the figure. Each branch distance corresponds to sequence divergence.
