| Abstract: | A portion of the mitochondrial 16S rRNA gene was compared between two color morphotypes of Gerres erythrourus, viz. “yellow type” and “white type,” obtained from Ryukyu Islands, Japan, and various areas of the Indo-Pacific, respectively.
Phylogenetic analyses showed that the haplotypes of each color morph were reciprocally monophyletic, supported by high bootstrap
values. The degree of sequence difference between the two color morphs was comparable to that existing between species of
the same complex as well as other distinct gerreid species. The genetic results together with their geographic range indicated
that the two color morphs represent two distinct species.
