Lithoglyphus fuscus (C. Pfeiffer, 1828) Findings in Serbia . Lithoglyphus fuscus : Möllendorff (1873) ; Karaman (2001) ( L. Dokić 1879 collection). Morphology . Small-sized snails up to 10 mm high. Globulous shell has pointed apex and 4-4.5 whorls. Suture is deep, aperture is ovate and angled at the top, with sharp peristome. Umbilicus is closed. For more details see Glöer (2019: 174 , fig. 216). Distribution and ecology . Central European species. In Serbia recorded in the Danube, Sava and Morava Rivers, and in pools near Paraćin . All those records are from the 19 th century. Other remarks . Type species of the genus. Bole (1981) argued that Lithoglyphus fuscus is a subspecies of L. naticoides characteristic for northern Balkan. Considering all known records are from the 19 th century, this species could be considered as non-present in the region nowadays. Moreover, Glöer (2019) considers the presence of this species only in the type locality in Slovenia ( Ljubljana ). On the IUCN Red List it has been assessed as LC ( Sket & Cioboiu 2010 ).
