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 Vitrinellidae is a family (biology), family of very small and minute sea snails with an Operculum (gastropod), operculum, marine (ocean), marine gastropod mollusks in the superfamily Truncatelloidea.MolluscaBase (2018). Vitrinellidae Bush, 1897. ...
