Remarks. Monterosato introduced this name with a brief description. He referred that the species matches the var. “ exilis ” Monterosato (nomen nudum) of Eulima distorta Deshayes 1830, and (with a question mark) Eulima distorta Deshayes 1830, sensu G.O. Sars (1878: pl. 11, fig. 23). We think that the introduction is valid due to the description rather than to the reference to Sars (1878). Thus, the type material is composed of the shells directly examined by Monterosato for this article. Pending a revision of the Mediterranean species of this difficult genus, it remains an open question whether this is a distinct species or not. Recorded by MolluscaBase (2018) as Vitreolina antiflexa (Monterosato, 1884).
