| Placostylus ambagiosus gardneri Powell, 1951 |
Placostylus ambagiosus gardneri is an extinct large terrestrial gastropod mollusc in the family Bulimulidae, endemic to the North Cape area in Northland in the North Island of New Zealand. It is subfossil in consolidated sand dunes at Tom Bowling Bay, Waikuku, and Whareana.
This is the heaviest built of all the New Zealand Placostylus. All five of the apertural processes are well developed, especially the parietal tubercle, which is either vestigial or absent in the other subspecies.
Height is up to 81 mm, and width up to 34 mm.
