Complete distribution of the genus Laevilitorina (Littorinimorpha, Littorinidae) in the Southern Hemisphere: remarks and natural history

A comprehensive analysis of the genus Laevilitorina, a marine gastropod found exclusively in the Southern Hemisphere, reveals significant insights into its distribution and diversity. The study, which combines field sampling, published records, and data from global biodiversity databases, identifies 21 species across regions including West Antarctica (8 species), New Zealand's sub-Antarctic islands (4 species), and Australia's south-east shelf (4 species). Notably, it highlights the rare occurrences of L. pygmaea and L. venusta, while also challenging the taxonomic status of L. caliginosa, suggesting it represents multiple divergent lineages rather than a single widespread taxon. This research underscores the need for further molecular and taxonomic studies to better understand the genus's diversity and biogeography.
