Status. Pontocaspian species, endemic to Caspian Sea.

Type locality. "Western Caspian Sea southeastwards from Derbent" ( Vinarski and Kantor 2016: 66).

Distribution. Caspian Sea (middle and southern Caspian Sea Basin). This species was mentioned from depths between 200 and 400 m in the South Caspian Basin of Azerbaijan ( Mirzoev and Alekperov 2017, who reported the species as Hypanis albida ).

Taxonomic notes. This species is part of a group of Caspian Monodacna with relative flat and wedge-shaped shells with low and sometimes poorly defined ribs ( M. albida , M. polymorpha ). Like for the Monodacna caspia group (see below), we are in need of studies to assess whether these taxa might form ecomorphs of a single species.

Conservation status. Not assessed.
