摘要胶纹螺属（Jesogammarus）分为胶纹螺亚属（Jesogammarus）和Annanogammarus亚属（Annanogammarus），共16种。为了研究该属物种之间的关系，分子系统发育研究，包括8个物种的前亚属和4个后者进行了使用线粒体COI和12S rRNA基因的部分DNA序列。基于COI和12S数据的MP、NJ和ML树表明Annanogammarus亚属的单系性，但Jesogammarus的单系性尚未解决。Jesogammarus（A.）naritai和J.（A.）suwaensis表现出低的遗传分化，并没有表现出相互单系，这表明这些类群的密切关系。
Abstract The genus Jesogammarus contains 16 species in two subgenera, Jesogammarus and Annanogammarus. To examine relationships among species in the genus, a molecular phylogenetic study including eight species of the former subgenus and four of the latter was conducted using partial DNA sequences of the mitochondrial COI and 12S rRNA genes. MP, NJ, and ML trees based on the combined COI and 12S data indicated monophyly of the subgenus Annanogammarus, though the monophyly of Jesogammarus was left unresolved. Consistent with few morphological differences, Jesogammarus (A.) naritai and J. (A.) suwaensis showed low genetic differentiation and did not show reciprocal monophyly, which suggests a close affinity of these taxa.
