| Placostylus ambagiosus hinemoa Powell, 1947 |
Placostylus ambagiosus hinemoa is an extinct large terrestrial gastropod mollusc in the family Bulimulidae, endemic to the Cape Maria van Diemen area in Northland in the North Island of New Zealand. It is found only on the offshore island of Motuopao, subfossil in consolidated dunes.
Compared with the typical Placostylus ambagiosus subspecies, this shell is of much heavier build and is proportionately broader with a greater spire angle. All five apertural processes are developed but the basal lip tubercle is the strongest.
Height is up to 82 mm, and width up to 37 mm.
