  • Rissoacea (suffix -oidea mandatory for a superfamily name following current ICZN art. 29.2.)
  • Rissoidea (misspelling)

Rissooidea, originally named Rissoacea by Gray, 1847, is a taxonomic superfamily of small and minute marine snails, belonging to the clade Littorinimorpha. [1]

With their phylogenetic analysis of rissooidean and cingulopsoidean families, Criscione F. & Ponder W.F. (2013) have created the superfamily Truncatelloidea containing many families previously included in the superfamily Rissooidea. They have shown that Rissooidea was not monophyletic, encompassing two major clades, i.e. Risooidea s.s. and Truncatelloidea. The freshwater, brackish water, and semi-terrestrial families and genera were brought under Truncatelloidea. [2]


Families within the superfamily Rissooidea include:

Genera unassigned to a family
Family names brought into synonymy
  • Ansolidae Slavoshevskaya, 1975: synonym of Barleeiidae Gray, 1857
  • Barleeidae Gray, 1857: synonym of Barleeiidae Gray, 1857
  • Rissoidea: misspelling of Rissooidea


This superfamily 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 the ICZN article 29.2. The suffix -oidea used to be used for some subclasses and superorders, where it is stll 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.[3][4][5]
