Limacoidei

The original ancestral area of limacoid families is thought to be the Palearctic region and south-eastern Asia. == Etymology ==

The word "limacoid" means "resembling a slug". == Typography of the name ==

In 1998, for the same taxon, Hausdorf with quotation marks like this: "limacoid clade". Other typographical variants are used by various other authors, for example capitalizing and restricting the use of the quote marks thus: "Limacoid" clade and "Limacoid clade". == 2003 taxonomy by Schileyko ==

The study of A. Schileyko in this group, published in parts 8–11 of his monograph between 2002 and 2003, did not discuss the system that Hausdorf had proposed. However, Schileyko refers to the work of Hausdorf, where this system was proposed, in part 10 (2003) on p. 1390. So he was acquainted with this system before 2003. Alternative taxonomy is as follows (subfamilies listed only for Helicarionidae and Zonitidae): • Superfamily Helicarionoidea • Family Euconulidae • Family Trochomorphidae • Family Helicarionidae • Subfamily Geotrochinae • Subfamily Helicarioninae • Subfamily Papuarioninae • Subfamily Urocyclinae • Family Gymnarionidae • Family Rhysotinidae • Family Ariophantidae • Family Ostracolethidae • Family Ryssotidae • Family Milacidae • Superfamily Dyakioidea • Family Dyakiidae • Family Staffordiidae • Superfamily Gastrodontoidea • Family Gastrodontidae • Superfamily Zonitoidea • Family Zonitidae • Subfamily Pristilomatinae • Subfamily Godwiniinae • Subfamily Zonitinae • Subfamily Oxychilinae • Family Daudebardiidae • Family Parmacellidae • Superfamily Trigonochlamydoidea • Family Trigonochlamydidae • Superfamily Vitrinoidea • Family Vitrinidae • Superfamily Limacoidea • Family Limacidae • Family Agriolimacidae • Family Boettgerillidae Moreover, after these groups, in the same infraorder Limacoinei, Schileyko listed six more superfamilies: Camaenoidea, Xanthonychoidea, Helicoidea, Polygyroidea, Hygromioidea and Arionoidea. == 2005 taxonomy by Bouchet & Rocroi ==

Explanatory note For this particular group of families, Bouchet & Rocroi adapted the taxonomic approach which was originally published by German malacologist Bernhard Hausdorf in 1998 in the Journal of Molluscan Studies. Bouchet & Rocroi clearly state, on p. 283: who attempted to explain the changes within this taxonomy to the public. This same error is reproduced in various other internet sources. Taxonomic list The taxonomy of Bouchet and Rocroi }} As explained in the previous section, the superfamilies Arionoidea and Helicoidea do not belong to the limacoid clade. However, they are sometimes mistakenly included in this taxon. ==References==
