Discopsis is a genus of small sea snails, marine gastropod mollusks in the family Tornidae. [1]
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. [1]
