Status. Accepted Pontocaspian species.

Type locality. Ukraine, in the Dniester River (exact locality not specified).

Distribution. Azov Sea and northern Black Sea Basin. Known from the Holocene of Danube Delta, Ukraine ( Anistratenko and Prisyazhniuk 1992).

Taxonomic notes. Clathrocaspia knipowitschii , C. makarovi , C. gmelini aluschtensis, and C. stanislavi were all described from the northern margin of the Black Sea. After detailed morphological comparison of C. knipowitschii and C. makarovi syn. n. and preliminary genetic analyses (TW, unpublished data), we conclude that both taxa should be considered synonyms. Very likely, also C. gmelini aluschtensis and C. stanislavi are synonyms of C. knipowitschii , but a final decision on that matter requires investigation of the type material.

Conservation status. Least Concern (same for C. makarovi ; Son 2011b, c).
