The identity of Meioceras elongatum de Folin, 1881 (Gastropoda, Caenogastropoda, Caecidae)

Meioceras elongatum de Folin, 1881, has been described from “mers de Chine” (China Seas) and was never recorded thereafter. The three syntypes are not conspecific and have probably a different origin. To stabilize the nomenclature, the specimen best fitting the original description and illustration is here selected as lectotype. As a consequence, Meioceras elongatum has to be considered a junior synonym of M. nitidum (Stimpson, 1851).
