A dozen species belonging to the Rhytididae can be found here,they are carnivorous snails.Other members of this family can be found in New Zealand. Some 40 species of operculate snails live here,Ditropis,Hedleya and Suavocallia are endemic.
New Zealand New Zealand has some very beautiful snailspecies of the Rhytidae family,namely Paryphanta and Powelliphanta(which were named Paryphanta before too).The name Paryphanta should apparently only be used for the Kauri snail:Paryphanta busbyi,Gray 1830. Powelliphanta snails live in North west Nelson and North Westland.They can also be found in the Marlborough Sounds and Mount Richmond Forest Park, as far south as Fiordland and Southland and,(across Cook Strait)on parts of the Kapiti Coast and into the central North Island. (source=Powelliphanta landsnails) They are carnivorous snails feeding on earthworms,slugs and other snails.
