| Placostylus ambagiosus watti Powell, 1947 |
Placostylus ambagiosus watti is a large rare terrestrial gastropod mollusc in the family Bulimulidae, endemic to the North Cape area in Northland in the North Island of New Zealand. It is found between Waikuku Beach and North Cape, under cover of coastal forest on cliff faces.
The shell is of lighter build than Placostylus ambagiosus whareana, and only the two outer-lip processes and the basal-lip tubercle are well developed, but never so strongly as in the whareana subspecies. Distinctive features of watti are an obscurely malleated or indistinctly spirally ridged surface, and a very dark chocolate-brown periostracum.
Height is up to 86 mm, and width up to 39 mm.
Placostylus ambagiosus watti is classified by the New Zealand Department of Conservation as being Nationally Critical.
