Abstract :A nucleotide sequence analysis of the mitochondrial DNA control region was conducted to reveal the genetic population structure and demographic history of the mottled spinefoot Siganus fuscescens (Houttuyn, 1782), and we discussed the taxonomic treatment of S. fuscescens and white-spotted spinefoot S. canaliculatus (Park, 1797) in terms of population genetics and morphological studies. Sequence analysis indicated that the haplotypes could be clearly divided into three lineages. Morphological analysis indicated no significant differences among measurements for the three genetically divergent lineages. We concluded that each lineage had once been isolated, and then former allopatric lineages may have resulted in the sympatric distribution of lineages due to secondary contact. Siganus fuscescens regards as valid species, and S. canaliculatus is a junior synonym of S. fuscescens.
