(Poppe, 1887) is a stenothermic glacial relict whose narrow environmental requirements make it an indicator species for good ecological conditions. The primary threats to this species are eutrophication and global warming. Many authors have described in taxonomic keys; however, its morphological description is unsatisfactory. Therefore, in this study, we aimed to review morphological characteristics of that were previously undescribed in the literature and to provide the molecular characteristics based on the two conservative mitochondrial genes: cytochrome oxidase I () and cytochrome (). The new record of indicates that it is a more widespread species than previously hypothesized. Width-to-length ratio of the last female endopod segment of legs indicates variation among the widely distributed species of the genus in Europe (i.e., , (Lilljeborg, 1853), and (Poppe, 1880)). We also found variability of number of setae on the second segment of male endopod. Furthermore, our analysis confirms the occurrence of species in different than exclusively freshwater habitats.
（波佩，1887年）是一种狭温性冰川残遗物种，其狭窄的环境要求使其成为良好生态条件的指示物种。该物种面临的主要威胁是富营养化和全球变暖。许多作者在分类学检索表中对其进行了描述；然而，其形态描述并不令人满意。因此，在本研究中，我们旨在回顾文献中先前未描述的[物种名称]的形态特征，并基于两个保守的线粒体基因：细胞色素氧化酶I（COI）和细胞色素b（CYTB）提供分子特征。[物种名称]的新记录表明它是一种比先前假设分布更广的物种。腿部最后雌性内肢节的宽长比表明欧洲该属广泛分布的物种（即[物种名称1]、[物种名称2] （利尔耶博里，1853年）和[物种名称3] （波佩，1880年））之间存在差异。我们还发现雄性内肢第二节上刚毛数量的变异性。此外，我们的分析证实了[物种名称]在非单纯淡水生境中的出现。
