根据线粒体细胞色素c氧化酶亚基I（COI）基因的核苷酸序列，对顺天湾采集的蟹实蝇属（Cerithidea）中的一个未鉴定的同源种（A种）进行了系统发育分析。并将其遗传结构与日本和琉球群岛附近的其他同属种及其当地种群进行了比较。一个C在顺天湾和八代群体中检测到cingulata单倍型，且在两个群体中均为最优势单倍型。利用邻接法（NJ）分析表明，物种A的单系性得到了很高的自举概率（100%）的支持，表明该物种与C.泰国产的阿拉塔和C.菲律宾的小翅目与蟹实总科其他种的亲缘关系较远。C. cingulata、环纹隐翅虫C. largillierti，C. djadjariensis和物种A种群在顺天湾的特点是低的遗传多样性。这些特征应归因于地理因素，进一步研究顺天湾和海湾外部栖息地的连通性可以揭示保护生态学中这个有趣的主题。
The phylogenetic relationship among the genus Cerithidea including an unidentified congeneric species referred here as species A collected in Suncheon Bay were inferred from nucleotide sequences of the mitochondrial gene for cytochrome c oxidase subunit I (COI). Their genetic structures were compared with other congeneric species and their local populations around Japan and Ryukyu Islands. A single C. cingulata haplotype was detected to be shared between the Suncheon Bay and Yatsushiro populations and it was the most dominant haplotype in both populatioms. The monophyly of species A was supported by a high bootstrap probability (100%) in the analysis using the neighbour-joining (NJ) method, which showed a closer relationship of this unidentified species with C. alata from Thailand and C. microptera from the Philippines than with other Cerithidea species. C. cingulata, C. largillierti, C. djadjariensis and species A populations in Suncheon Bay can be characterized by a low genetic diversity. These characteristics should be attributed to geographical factors, and further study of the connectivity of Suncheon Bay and the habitats in the outside of the bay could shed light on this interesting theme in conservation ecology.
