? = Feneoniana Kolesnikov, 1939 †

Type species. Trochus feneonianus d’Orbigny, 1844, OD (Kolesnikov 1939: 701), established as section within Calliostoma Swainson, 1840 . Middle-late Miocene (Bessarabian), Eastern Paratethys (Russia).

Remarks. Feneoniana is available according to Article 10.4 of the ICZN, which states: “ A uninominal name proposed for a genus-group division of a genus, even if proposed for a secondary (or further) subdivision, is deemed to be a subgeneric name even if the division is denoted by a term such as “section” or “division””. Kolesnikov (1939) unites a morphologically very heterogenous group of species in Feneoniana . The type species, Trochus feneonianus d’Orbigny, 1844, is close to Sarmatigibbula, aside from the more rounded shoulder and the open umbilicus. Sladkovskaya (2017) treats Trochus feneonianus as Gibbula s.s. As it remains unclear if Feneoniana is really a synonym of S armatigibbula, Trochus feneonianus is listed herein as Gibbula s.l. If further revisions would corroborate the synonymy of Feneoniana and Sarmatigibbula, Feneoniana would have precedence.
