Abstract

The population genetic structures of S. vanluni, S. cheongi and S. jeffreyi were determined from mitochondria-encoded sequences of cytochrome c oxidase subunits I (COI) across different states in Peninsular Malaysia. High levels of genetic diversity and genetic differentiation were observed among three species. All three species revealed an intermediate level of gene flow among the populations. Negative values of Fu's Fs and low values of Raggedness index supported the hypothesis of population expansion in S. vanluni, S. cheongi and S. jeffreyi.
