      Two groups of Powelliphanta are of particular interest due to threats to their habitat.

Powelliphanta traversi, known as Travers' land snail, is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family species is endemic to the North Island of New Zealand between Wellington and Lake Waikaremoana. There are six subspecies, all of which are listed by the New Zealand Department of Conservation as Class: Gastropoda.

Powelliphanta is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New are carnivorous, eating invertebrates, mostly native restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or : Gastropoda.
