Freshwater mussels (Bivalvia, Unionida) play essential roles in the well-functioning of ecosystems, even providing essential services to humans. However, these bivalves face numerous threats (e.g. habitat loss and fragmentation, pollution, introduction of invasive species, and climate change) which have already led to the extinction of many populations. This underscores the need to fully characterize the biology of these species, particularly those, such as , that are still poorly studied. This study presents the first mitogenome of (Kobelt, 1879), an endemic species of Greece with a distribution limited to only two river basins. The mitochondrial genome of a specimen, collected at Pamisos River (Peloponnese, Greece), was sequenced by Illumina high-throughput sequencing. This mitogenome (16,101 bp) is characterized by 13 protein-coding genes, 22 transfer RNA and 2 ribosomal RNA genes. The size of this mitogenome is within the range of another mitogenome already published for the species . In the phylogenetic inference, was recovered as monophyletic with mitogenome in the Lamprotulini tribe, as expected. This genomic resource will assist in genetically characterizing the species, potentially benefiting future evolutionary studies and conservation efforts.
淡水贻贝（双壳纲，蚌目）在生态系统的良好运转中发挥着重要作用，甚至为人类提供重要服务。然而，这些双壳类动物面临着众多威胁（如栖息地丧失和破碎化、污染、入侵物种的引入以及气候变化），这些威胁已经导致许多种群灭绝。这凸显了全面描述这些物种生物学特性的必要性，特别是那些研究仍很匮乏的物种，比如[具体物种名称未给出]。本研究展示了[具体物种名称未给出]（科贝尔特，1879年）的首个线粒体基因组，该物种是希腊的特有物种，分布仅限于两个流域。对在希腊伯罗奔尼撒半岛帕米索斯河采集的一个[具体物种名称未给出]样本的线粒体基因组进行了Illumina高通量测序。这个线粒体基因组（16,101 bp）由13个蛋白质编码基因、22个转运RNA基因和2个核糖体RNA基因组成。该线粒体基因组的大小在已发表的该物种另一个线粒体基因组的范围内。在系统发育推断中，正如预期的那样，[具体物种名称未给出]与Lamprotulini部落中的[具体物种名称未给出]线粒体基因组一起被归为单系类群。这种基因组资源将有助于对该物种进行基因特征描述，可能有益于未来的进化研究和保护工作。
