? Laevicaspia marginata (Westerlund, 1902)

*1902a Nematurella marginata Westerlund: 45.

2013 Pyrgula marginata (Westerlund, 1902). - Vinarski et al.: 85, fig. 2F.

2016 Pyrgula marginata (Westerlund, 1902). - Vinarski and Kantor: 240.

Status. Pontocaspian species, identity uncertain.

Type locality. Caspian Sea, "near Krasnojarsk" (Westerlund 1902a). This statement is clearly erroneous since Krasnojarsk is situated in Siberia. Most probably, Westerlund meant Krasnovodsk (nowadays Turkmenbashi) in Turkmenistan (Vinarski et al. 2013).

Distribution . Endemic to the Caspian Sea. This species was mentioned from depths between 200 and 300 m in the South Caspian Basin of Azerbaijan (Mirzoev and Alekperov 2017, who reported the species as Turricaspia marginata).

Taxonomic notes. The status of this species is uncertain. The illustrations of the type material by Vinarski et al. (2013) suggest a tentative placement in the genus Laevicaspia . It shows close similarities with L. sieversii (Clessin in Dybowski, 1887). A careful revision of the species is required to clarify its taxonomic status and systematic placement.

Conservation status. Not assessed.
