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, all of which are classified by the New Zealand Department of Conservation as being Nationally Endangered.

  • Powelliphanta superba harveyi
  • Powelliphanta superba mouatae
  • Powelliphanta superba prouseorum
  • Powelliphanta superba richardsoni
  • Powelliphanta superba superba


Adults can reach the size of a man's fist, with shells in patterns of deep reds, blacks and browns. They are predators of slugs and earthworms, and possibly other small, soft bodied forest floor dwellers. They require moist environments, and as such tend to live in moist mountain forests. Even the empty shells are not exempt, and if stored dry for to long will crack, and eventually may shatter dramatically into many tiny pieces. The eggs are oval and seldom constant in dimensions 14 by 12 millimetres (0.55 in × 0.47 in).
