Discopsis is a genus of small sea snails, marine gastropod mollusks in the family Tornidae.Bouchet, P.; Gofas, S. (2014). Discopsis de Folin, 1870. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138558 on 2014-12-10
Taxonomy Rolán & Rubio (2002: 46) hold Discopsis as a valid genus, distinct from Cochliolepis Stimpson, 1858, on the grounds that the latter belongs in the family Vitrinellidae and the former in Tornidae. This should be reevaluated in the perspective that both families are considered synonyms. Adam & Knudsen (1969) may have been right in placing the West African species in Cochliolepis.
Description (Original description in Latin) The shell is discoid and very depressed, with a distinct umbilicus. The aperture is strongly oblique, and its margins are joined across the penultimate whorl by a thickened siphonal canal. Folin L. de & Périer L. (1867-1887). Les fonds de la mer. Paris: Savy. 4 volumes, p. 205
