- Suborder Helicina ("Non-Achatinoid Clade")
- Infraorder Arionoidei
- Infraorder Clausilioidei
- Infraorder Helicoidei: formed from Helicoidea Rafinesque, 1815 and Sagdoidea Pilsbry, 1895[3]
- Infraorder Limacoidei: formed from original limacoid clade
- Infraorder Oleacinoidei[4]
- Oleacinoidea: formed from original Testacelloidea but with the family Testacellidae excluded;
- Haplotrematoidea: formed from original Rhytidoidea and Haplotrematidae[5]
- Infraorder Orthalicoidei
- Infraorder Pupilloidei (Orthurethra)
- Infraorder Rhytidoidei: formed by Rhytidoidea merging with contents from Acavoidea.
