Status The genus, which is based on a species described from supposedly Eocene strata of Balouk Keui near Alexandroupoli, NE Greece, was initially conceived to be a terrestrial slug (“limacien”) by Deshayes (1857). Based on findings in Sarmatian (middle Miocene) deposits in the Dardanelles of what was believed to be the same species, Gude (1912) suggested that Viquesnelia is probably not a terrestrial snail but the operculum of a viviparid, perhaps of the genus Tylopoma Brusina, 1882. While it is questionable whether the Eocene and the Sarmatian fossils are related, the resemblance of Viquesnelia lenticularis with an operculum is indeed striking. The relationship with Tylopoma is unlikely, since that genus is only known from latest Miocene to Pliocene deposits of Croatia, Romania and Georgia.
Since the taxonomic validity, the systematic position and the stratigraphic age of Viquesnelia are doubtful, the taxon is regarded as a nomen dubium. The suggestion by Gude (1912) to place it in the Viviparidae is followed. [details]
