Genus Cupaniella M. Gemmellaro, 1911

Type species – Cupaniella biplicata M. Gemmellaro, 1911

Remarks – GEMMELLARO (1911) thought his new genus, Cupaniella as belonging to Cerithiidae . However, its morphology shows doubtless relationships to genera of Chilodontidae , especially to Wilsoniconcha Wenz, 1938 (nom. nov. pro Wilsonia Hudleston, 1896 ); possibly, they are synonymous. For the first glance, the type species of the two genera do not differ on higher than the species level. Both seem to have a pair of columellar denticles in similar position; however, they are the terminal parts of two columellar folds in Cupaniella ; but the interior in the type species of Wilsoniconcha is unknown. The probability of synonymy increased as GRÜNDEL (2007) published his new species, Wilsoniconcha ? tora, from the Liassic (Carixian = Early Pliensbachian) of Normandy; this species has also two columellar folds, i.e. it belongs to Cupaniella .
