Turricaspia eburnea (Logvinenko & Starobogatov, 1969)

*1969 Pyrgula (Laevicaspia) eburnea Logvinenko & Starobogatov: 370, fig. 365(1).

2016 Turricaspia eburnea (Logvinenko & Starobogatov, 1968). - Vinarski and Kantor: 247.

Status. Pontocaspian species, identity uncertain.

Type locality. Eastern part of the southern Caspian Sea.

Distribution. South Caspian Basin. This species was mentioned from depths between 200 and 500 m in the South Caspian Basin of Azerbaijan (Mirzoev and Alekperov 2017).

Taxonomic notes. The identity of this species is unclear. Its shell resembles T. lyrata (Dybowski & Grochmalicki, 1915) in terms of general shape and the large, flat protoconch; it differs from that species in the large size. The type material has been very recently found in the collection of ZIN and awaits further study. Until then, we refrain from a final decision on the species’ status, but we have severe doubt that Pyrgula eburnea is a distinct species.

Conservation status. Not assessed.
