Rissooidea (originally named Rissoacea by Gray in 1847) is a superfamily of tiny marine snails.Gofas, S. (2013). Rissooidea. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=14767 on 2013-06-04

Following their phylogenetic analysis of snails in the rissooidean and cingulopsoidean families in 2013, Criscione F. and Ponder W.F. determined that Rissooidea was not monophyletic, and created the superfamily Truncatelloidea, which encompasses many families previously included in the superfamily Rissooidea. Several freshwater, brackish, and semi-terrestrial families and genera within Rissooidea were brought under Truncatelloidea.

Families Families within the superfamily Rissooidea include: Barleeiidae Gray, 1857 Emblandidae Ponder, 1985 Lironobidae Ponder, 1967 † Mesocochliopidae Yu, 1987 † Palaeorissoinidae Gründel & Kowalke, 2002 Rissoidae Gray, 1847 Rissoinidae Stimpson, 1865 Zebinidae Coan, 1964

Nomenclature The Rissooidea family was previously known as Rissoacea. Prior to the recent ruling by the ICZN, many invertebrate superfamily names ended in the suffix -acea, or -aceae, not -oidea as now required according to ICZN article 29.2. The suffix -oidea was formerly used for some subclasses and superorders, where it is still found. In much of the older literature, including Keen 1958, Moore et al. 1952, and the Treatise on Invertebrate Paleontology, gastropod superfamilies are written with the suffix -acea.Keen A. M. (1958). Sea Shells of Tropical West America. Stanford University Press.Moore, Lalicker & Fischer (1952).Invertebrate Fossils. McGraw-Hill Book.Treatise on Invertebrate Paleontology; part K (Nautiloidea) 1964 and part L (Ammonoidea) 1962; Geological Society of America and Univ. of Kansas Press.
