Oysters are sessile, filter-feeding bivalve molluscs widely distributed in estuarine and coastal habitats worldwide. They constitute a valuable resource for fisheries and extensive aquaculture and provide essential ecological services. Yet, their genetic diversity and distribution remain understudied. The variability in shell morphology complicates species classification, which is influenced by environmental and genetic factors. Although molecular phylogenetics research has refined oyster taxonomy and identified approximately 100 extant species, numerous taxonomic uncertainties persist. In the present study, we aimed to document the occurrence of small flat oysters of the genus along the Mediterranean coastal areas of Liguria and Sardinia (Italy). Specifically, 16S rRNA sequence data were used to identify species. Our findings offer novel insights into the species complex and , a new species in the Mediterranean coastal areas of Italy. The study data further our understanding of species diversity, distribution, and evolutionary patterns.
牡蛎是固着生活、滤食性的双壳贝类软体动物，广泛分布于世界各地的河口和沿海栖息地。它们是渔业和大规模水产养殖的宝贵资源，并提供重要的生态服务。然而，它们的遗传多样性和分布情况仍未得到充分研究。壳形态的变异性使物种分类变得复杂，这受到环境和遗传因素的影响。尽管分子系统发育学研究已经完善了牡蛎分类学并确定了约100个现存物种，但仍存在许多分类学上的不确定性。在本研究中，我们旨在记录利古里亚和撒丁岛（意大利）地中海沿岸地区小贻贝属小贻贝的出现情况。具体而言，利用16S rRNA序列数据来鉴定该物种。我们的研究结果为贻贝物种复合体以及意大利地中海沿岸地区的一个新物种提供了新的见解。研究数据进一步加深了我们对贻贝物种多样性、分布和进化模式的理解。
