? Turricaspia obventicia (Anistratenko in Anistratenko & Prisyazhniuk, 1992)

*1992 Caspia (Clathrocaspia) obventicia Anistratenko in Anistratenko & Prisyazhniuk: 19-20, fig. 2b.

Status. Uncertain Pontocaspian species.

Type locality. Well 37 near Kiliya, Izmail district, Odessa region, Ukraine (from Holocene sediments).

Distribution. Type locality only.

Taxonomic notes. This species was originally attributed to the genus Caspia due to its small shell. A study of the holotype of this species, specifically its protoconch characteristics, suggest placement in the genus Turricaspia . Further studies are required to assure its validity.

Remarks. The species is known only from the holotype. The occurrence of Turricaspia in the Black Sea Basin is unusual, as almost all other pyrguline Black Sea species are assigned to the genus Laevicaspia (but see remark at T. spica for another unusual occurrence).

Conservation status. So far only known from Holocene deposits of the type locality; species might be extinct.
