Distribution and Occurrences of Laevilitorina across the Southern Hemisphere

Littorinids are present in most of the coastal areas in the world, playing a significant role in the ecology of intertidal communities. Laevilitorina is a marine gastropodos genus distributed exclusively in the Southern Hemisphere, with 21 species reported at South America, sub-Antarctic Islands, Antarctic, New Zealand, Tasmania and Australia. We present an updated database of these 21 species of Laevilitorina generated from a combination of four sources: 1) new field sampling data and 2) published records, 3) Global Biodiversity Information Facility (GBIF), and 4) Atlas of Living Australia (ALA); to provide a comprehensive description of the geographic distribution of the genus through its distribution.

littorinids（滨螺科）广泛分布于全球大多数沿海地区，在潮间带生态系统中扮演着举足轻重的角色。Laevilitorina（拉维利托里纳属）是一种仅分布于南半球的海洋软体动物门腹足纲螺类，据记载，该属共有21个物种，分布于南美洲、亚南极群岛、南极洲、新西兰、塔斯马尼亚和澳大利亚。本研究呈现了由四个来源整合而成的这21个物种的更新数据库：1）新的野外采样数据；2）已发表的记录；3）全球生物多样性信息设施（GBIF）；4）澳大利亚活体地图（ALA）；旨在全面描述该属的地理分布及其分布特征。
