'''Sorbeoconcha''' is a [[Taxonomy (biology)|taxonomic]] [[clade]] of [[snail]]s, i.e. [[gastropod]]s, mainly [[marine (ocean)|marine]] species with [[gill]]s and [[Operculum (gastropod)|opercula]], within the [[clade]] [[Caenogastropoda]].

The [[taxon]] Sorbeoconcha was named by [[Winston Ponder]] and [[David R. Lindberg]] in 1997.

==Taxonomy==

===1997 taxonomy===
According to the older taxonomy by Ponder and Lindberg the suborders within the order Sorbeoconcha are:
* [[Discopoda]] P. Fischer, 1884
* [[Murchisoniina]] Cox & Knight, 1960
* [[Hypsogastropoda]] Ponder & Lindberg, 1997
* [[Cerithiimorpha]] Golikov & Starobogatov, 1975

===2005 taxonomy===
In the [[Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005)|taxonomy by Bouchet & Rocroi (2005)]],<ref name="Bouchet">Bouchet P. & Rocroi J.-P. (Ed.); Frýda J., Hausdorf B., Ponder W., Valdes A. & Warén A. 2005. ''Classification and nomenclator of gastropod families''. Malacologia: International Journal of Malacology, 47(1-2). ConchBooks: Hackenheim, Germany. {{ISBN|3-925919-72-4}}. {{ISSN|0076-2997}}. 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278</ref> the [[clade]] Sorbeoconcha was declared a taxon of unspecified rank, within the clade [[Caenogastropoda]].

It comprises the [[Taxonomic rank|superfamily]] [[Cerithioidea]], the superfamily [[Campaniloidea]], the [[Informal group (taxonomy)|informal group]] [[Ptenoglossa]] and the clade [[Neogastropoda]].

The following families were not allocated to a superfamily:
* † [[Acanthonematidae]] Wenz, 1938
* † [[Canterburyellidae]] Bandel, Gründel &  Maxwell, 2000
* ''[[Globocornidae]]'' <small>Espinosa & Ortea, 2010</small>
* † [[Prisciphoridae]] Bandel, Gründel & Maxwell, 2000

The [[World Register of Marine Species]] considers Sorbeoconcha an alternate representation of Caenogastropoda and gives the following reasoning:
 
Sorbeoconcha should include [Cerithioidea + Campaniloidea + all Hypsogastropoda (i.e. the remaining Caenogastropoda)], see definition in Ponder & Lindberg, 1997: 225, not only [Cerithioidea + Campaniloidea] as suggested by the indent pattern in Bouchet & Rocroi.

Neotaenioglossa Haller, 1892 suggested in Ruud Bank’s draft for Fauna Europaea is not retained because it would need severe emendation to remove Pyramidellids, Cerithioids, etc.. included in its original definition, and therefore would be too far from Haller's concept if it were to fit the concept of Sorbeoconcha.

Although cladistically sound, the taxon Sorbeoconcha is skipped in the classification scheme because (1) ten years after its publication, the name still sounds unfamiliar to most and (2) it is not very helpful in the classification because it includes the bulk of Caenogastropoda (only keeping out small stem groups Abyssochrysidae, Provannidae, and the architaenioglossate taxa). This is not final, opinions are welcome.
