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., 論文}, pages = {61--85}, title = {Genetic isolation of the mottled spinefoot Siganus fuscescens Ryukyu Archipelago population}, volume = {17}, year = {2015} }
