The shells of the snails in this genus can be as large as 4.5 inches (11 cm) in maximum dimension.

Many species within this genus are now extinct.

Taxonomy edit

Placostylus is the type genus of the family Placostylidae.[4] It was placed within Placostylidae.[4]

Breure et al. (2010)[5] moved Prestonella and Bothriembryon to Placostylidae. Subsequently, Breure & Romero (2012)[3] confirmed previous results from 2010 and they renamed Placostylidae to Bothriembryontidae.[3]

Distribution edit

This genus of snails occurs in the Solomon Islands, Vanuatu, New Caledonia, Fiji, Lord Howe Island, and Northland in New Zealand. There are three species in New Zealand and no subspecies.[6]

Species edit

In former classification, two subgenera were recognized: subgenus Basileostylus Haas, 1935[7][8] subgenus Maoristylus Haas, 1935[9][8]

Species within this genus include:
