Miocene land snails (Mollusca: Gastropoda: Pulmonata) from palaeolake Manuherikia, southern New Zealand

Eight species of terrestrial Mollusca are recorded from Early–Middle Miocene sediments from palaeolake Manuherikia, near St Bathans, central Otago, New Zealand. Five new charopid species are described in Cavellia Iredale, 1915, Charopa Martens, 1860 and Fectola Iredale, 1915, a new genus Dendropa, based on the Recent species Flammulina pilsbryi Suter, 1894, Neophenacohelix Cumber, 1961, which is resurrected from synonymy under Phenacohelix Suter, 1892, and two new species of punctid are described in Paralaoma Iredale, 1913 and Atactolaoma n. gen. All genera involved are endemic to New Zealand and are the first pre-Quaternary records. A rhytidid is also recorded, which, though indeterminable, is the earliest record of the family. The three other confirmed pre-Quaternary (Late Pliocene) records of land snails are briefly discussed.
