Littorinid snails are present in most coastal areas globally, playing a significant role in the ecology of intertidal communities. is a marine gastropod genus distributed exclusively in the Southern Hemisphere, with 21 species reported from South America, the sub-Antarctic islands, Antarctica, New Zealand, Australia and Tasmania. Here, an updated database of 21 species generated from a combination of sources is presented: 1) new field sampling data; 2) published records; 3) the Global Biodiversity Information Facility (GBIF) and The Atlas of Living Australia (ALA), to provide a comprehensive description of the known geographic distribution of the genus and detailed occurrences for each of the 21 species. The database includes 813 records (occurrences), 53 from field sampling, 174 from the literature, 128 from GBIF, and 458 from ALA. West Antarctica had the highest species richness (8 species), followed by sub-Antarctic islands of New Zealand (4 species) and the south-east shelf of Australia (4 species). The provinces of Magellan, New Zealand South Island, and sub-Antarctic Islands of the Indian Ocean include two species each. This study specifically highlights reports of and , species that have been almost unrecorded since their description. Recent advances in molecular studies of showed that this species does not correspond to a widely distributed taxon, but to multiple divergent lineages distributed throughout the Southern Ocean. Ongoing molecular and taxonomic studies are necessary for a better understanding of the diversity and biogeography of this genus.
滨螺在全球大多数沿海地区都有分布，在潮间带群落生态中发挥着重要作用。滨螺属是一种仅分布于南半球的海洋腹足纲动物属，据报道在南美洲、亚南极岛屿、南极洲、新西兰、澳大利亚和塔斯马尼亚有21个物种。在此，展示了一个由多种来源组合生成的包含21个物种的更新数据库：1）新的野外采样数据；2）已发表记录；3）全球生物多样性信息设施（GBIF）和澳大利亚生物图谱（ALA），以全面描述该属已知的地理分布以及21个物种中每个物种的详细出现情况。该数据库包括813条记录（出现情况），其中53条来自野外采样，174条来自文献，128条来自GBIF，458条来自ALA。南极西部物种丰富度最高（8种），其次是新西兰的亚南极岛屿（4种）和澳大利亚东南陆架（4种）。麦哲伦省、新西兰南岛和印度洋亚南极岛屿各有两个物种。本研究特别强调了[具体物种1]和[具体物种2]的报告，这两个物种自被描述以来几乎未被记录。[具体物种]分子研究的最新进展表明，该物种并非对应一个广泛分布的分类单元，而是对应分布于南大洋的多个不同谱系。持续开展分子和分类学研究对于更好地理解该属的多样性和生物地理学是必要的。
