Clathrocaspia isseli (Logvinenko & Starobogatov, 1969)

*1969 Pyrgula (Caspia) isseli Logvinenko & Starobogatov: 378, fig. 367(6).

2016 Pyrgula isseli Logvinenko & Starobogatov, 1968. - Vinarski and Kantor: 239.

Status. Pontocaspian species, identity uncertain.

Type locality. Southern Caspian Sea (no details), between 40-75 m water depth.

Distribution. Endemic to the Caspian Sea.

Taxonomic notes. This species hardly differs from C. pallasii and might be a junior synonym. Observations on Holocene material from the southern and northern Caspian Sea shores (VA, TN, FW) suggest that the minor differences range within intraspecific variability but further studies (preferentially involving DNA) are required to solve the identity of this taxon. The classification in Clathrocaspia is based on the reticulate sculpture typical of that genus.

Conservation status. Data Deficient (Vinarski 2011j).
