  • 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.
  • Infraorder Succineoidei (Elasmognatha)
