Powelliphanta Sp.Baton is a rare undescribed and endangered large terrestrial mollusc in the family Rhytididae, endemic to the South Island of New Zealand. It is found only at the headwaters of the Baton River in the Kahurangi National Park in the north west of the South Island.
The shiny shell has a rounded bulbous appearance and a raised apex. It is a warm mid-brown to tan colour, with a few, very sparse, narrow reddish axial streaks. The colour of the mantle and mucous is faint blue, unlike the transparent appearance in most other Powelliphanta.
Major diameter is up to 39 mm, and height up to 19 mm.
Powelliphanta Sp.Baton is classified as Nationally Critical by the New Zealand Department of Conservation.
