Abeskunus depressispira (Logvinenko & Starobogatov, 1969)

*1969 Pseudamnicola (Abeskunus) depressispira Logvinenko & Starobogatov: 381, fig. 367(14).

2016 Pseudamnicola depressispira Logvinenko & Starobogatov, 1968. - Vinarski and Kantor: 222-223.

Status. Accepted Pontocaspian species.

Type locality. Western part of the southern Caspian Sea, northward of Kuraginsky Kamen’ [= Kür Daşı] Island (approximately 39°01'05"N, 49°20'02"E), 81 m water depth.

Distribution. In addition to the type locality, specimens have been found in Holocene material retrieved near the Kura Delta, a few kilometres north of the type locality.

Taxonomic notes. Current investigations on recently collected Holocene material from the south-western Caspian Sea confirm that this species belongs to the genus Abeskunus . The finely ribbed, low trochiform shell facilitates distinction from its congeners. The species epithet is based on the Latin noun spira, spire, and is to be considered a noun in apposition ( ICZN 1999, Art. 31.2.1.).

Conservation status. Data Deficient ( Vinarski 2011d).
