Status. Accepted species, invasive.

Type locality. New Zealand (no details).

Distribution. Originally from New Zealand, probably introduced in 1859 to England, in 1872 to Tasmania, in 1895 to mainland Australia, in ca. 1900 to European mainland ( Ponder 1988), and in 1987 to North America ( Zaranko et al. 1997).

Taxonomic notes. The two Black Sea species P. polistchuki syn. n. and P. alexenkoae syn. n. are here considered as junior synonyms of P. antipodarum , differing only very weakly in outline. Vinarski and Kantor (2016) listed Pyrgula ( Trachycaspia ?) grossui syn. n. Golikov & Starobogatov in the synonymy of T. dimidiata (Eichwald, 1838). Golikov and Starobogatov (1966) introduced this species as new name for the supposedly misidentified Potamopyrgus jenkinsi sensu Grossu (1951) from Razim Lake in Romania. The shell they later illustrated ( Golikov and Starobogatov 1972) indeed shows similarities with T. dimidiata . The shell illustrated in Grossu (1951), however, is completely different and shows a keeled form of P. antipodarum .

Conservation status. Least Concern ( Van Damme 2013).
