? Turricaspia aenigma (Logvinenko & Starobogatov, 1969)

*1969 Pyrgula (Celekenia) aenigma Logvinenko & Starobogatov: 375, fig. 366(12).

2016 Pyrgula aenigma Logvinenko & Starobogatov, 1968. - Vinarski and Kantor: 235.

Status. Pontocaspian species, identity uncertain.

Type locality. Caspian Sea, northward of Apsheron Peninsula, 75 m.

Distribution. Type locality only.

Taxonomic notes. The identity of this species is unclear. The illustrations of the holotype in Kantor and Sysoev (2006) show a small shell with four whorls, of which the latter two bear a distinct keel. The small size and the relatively large protoconch suggest that the type specimen is a juvenile shell. More specimens (including adult material) are required to shed light on this species’ identity.

Conservation status. Not assessed.
