The limacoid clade is a taxonomic clade of air-breathing land snails, semislugs and slugs, terrestrial pulmonate gastropod molluscs in the informal group Sigmurethra.
The original ancestral area of limacoid families is thought to be the Palearctic region and south-eastern Asia.
The word "limacoid" means "resembling a slug".
In 1998, for the same taxon, Hausdorf used the name Limacoidea sensu lato.
The name of this taxon, the limacoid clade, was written by Bouchet & Rocroi (2005) 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".
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 page 1390. So he was acquainted with this system before 2003.
Alternative taxonomy is as follows (subfamilies listed only for Helicarionidae and Zonitidae):
Moreover, after these groups, in the same infraorder Limacoinei, Schileyko listed six more superfamilies: Camaenoidea, Xanthonychoidea, Helicoidea, Polygyroidea, Hygromioidea and Arionoidea.
