Achatinoidea Swainson, 1840

The Achatinoidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the informal group Sigmurethra.[1]

This taxonomy was based on the study by Nordsieck, published in 1986. [2]


* Family Achatinidae Swainson, 1840
* Family Ferussaciidae Bourguignat, 1883
* Family Micractaeonidae Schileyko, 1999
* Family Subulinidae P. Fischer & Crosse, 1877
* Family Prestonellidae van Bruggen, 1978 : This enigmatic family, of which the phylogenetic relationships are unknown, has been tentatively placed here by Bouchet & Rocroi, based on biogeographical reaons. However, a study by Herbert and Mitchell, published in 2008, now places it in the Gondwanan superfamily Orthalicoidea [3]
