Type material. Kantor & Sysoev (2006: 99) stated that in ZIN no identified material of this species is found. We detected a lot in the ZIN collection of Starobogatov with six specimens and determined as “ Caspia derzhavini ”. Since this material is a single lot that was labelled by Starobogatov himself it is very likely the type material .
Type locality. Caspian Sea, probably near Cheleken Peninsula ( Table 1 View TABLE 1 , locality 21).
Other material. None.
Remarks. The shells of this species have a very slender elongate shape, and the protoconch ornamentation differs largely of that found in Caspiinae , showing irregular spiral threads on a smooth surface. Shape and protoconch features strongly remind of Laevicaspia ( Neubauer et al. 2018) . The small size and the short shell with only about five whorls suggest L. derzhavini is a juvenile Laevicaspia , and it might well be a synonym of a previously described Laevicaspia species. This problem cannot be properly solved from the material available for the species, which is why we consider L. derzhavini as a nomen dubium.
Distribution. Middle and South Caspian Sea, 45–81 m ( Logvinenko & Starobogatov 1969). Tarasov (1996b) mentioned the species from 311– 870 m.
