English The dasycladale Clypeina helvetica was described and illustrated with six drawings by Morellet and Morellet (Bull Soc Géol Fr 4o ser 18:102–105, 1918) from the “Bartonian” of the Helvetic Zone of southwestern Switzerland. Since then, C. helvetica has not been reported again neither from Switzerland nor from any other locality. Abundant material sampled from the Priabonian Diablerets Member of the Sanetsch Formation in the type area Lapis de Tsanfleuron permits a more detailed description of the species including biometric data and thin-section illustrations. C. helvetica is validated by the designation of a lectotype to serve as nomenclatural type.
