Powelliphanta superba is a species of large, carnivorous land snail in the family Rhytididae, which is endemic to the South Island of New Zealand. Five subspecies are recognised, [1] all of which are classified by the New Zealand Department of Conservation as being Nationally Endangered. [2]
Powelliphanta superba was originally described as Paryphanta superba by Arthur William Baden Powell in 1930. [3] The paratype specimens are located at Auckland War Memorial Museum. [3]
There are five subspecies of P. superba:
The eggs are oval and seldom constant in dimensions 14 by 12 millimetres (0.55 in × 0.47 in). [4]
Each of the five subspecies are listed as Threatened under the most recent assessment (2007) of the New Zealand Threatened Classification for Powelliphanta. [5] [6] Four are listed as Nationally Endangered, while P. superba superba is listed as Serious Decline. [5] [6]
Powelliphanta is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New Zealand. They are carnivorous, eating invertebrates, mostly native earthworms. Often restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or endangered.
