Abstract

A freshwater limpet, Latia manuherikia n. sp., is described from lacustrine beds of the Early–Middle Miocene lower Bannockburn Formation (Manuherikia Group), near St Bathans, Central Otago, southern New Zealand. The new species is the first fossil record of Latia, as well as the first record of the genus from the South Island. Latia is closely related to South American genus Chilina Gray, 1828, and the two groups presumably have a vicariant Gondwanan origin.

Key words: Mollusca, taxonomy, fossil, morphology, shell, vicariance, Gondwanaland
