(Previously this superfamily was in the order Cocculiniformia.) [1] DescriptionSpecies in this superfamily have undivided shell muscles (except Lepetellidae). They possess secondary gill leaflets or their gills are reduced. Their radula contains a well-developed rachidian tooth. The soft body lacks subpallial (i.e. below the mantle) glands. They have paired kidneys with the right one larger. Their testes and ovary are separate, (but species in the subfamily Choristellinae are gonochoristic, i.e. with distinct males and females) The ciliated gonoducts (the ducts through which the gametes reach the exterior) contain no glands.[2] FamiliesFamilies within the superfamily Lepetelloidea include:
