30. Lithoglyphus apertus ( Küster, 1852)

Findings in Serbia.

Lithoglyphus apertus: Radoman (1983) ; Jovanović (1991); Karaman (2001); Karaman & Karaman (2007).

Morphology. Medium-sized snails. Globulous thick-walled shell is up to 13 mm high, with five whorls, and short spire. The first whorls are slowly growing, and flattened at the suture. For more details see Glöer (2019: 174, fig. 215).

Distribution and ecology. Pontic species, inhabiting a muddy substrate of large slow-flowing rivers in the region ( Glöer 2019). In Serbia, it has been recorded in the Sava and Danube Rivers, near Belgrade.

Other remarks. Glöer (2019) considering morphology argues that Lithoglyphus . apertus probably could be just one of the forms of widespread and variable L. naticoides . On the IUCN Red List of threatened species it has been assessed as DD (Cioboiu et al 2010). The species is protected on national level (Annex 1-strictly protected species; Official Gazette of RS 5/2010, 47/2011, 32/2016, 98/2016).
