Type locality CROATIA • 1- “Plješevica-Gola bei Priboj”. Description SHELL . Closely spaced riblets on last part of protoconch. Teleoconch with two lines of reddish spots on whorls. Quite closely spaced ribs on teleoconch. Very strong lip with abrubtly inwardly curved columellar lobe covering umbilicus. MEASUREMENTS . 2 ♀♀ from Plješevica: whorls= 7.1–7.5, H =6.9–7.0 mm, H/W=2.50–2.6, roundness =0.16–0.17, ribs incl.=66–67°, apert. incl.= 13–17°, ribs/mm 1 st wh.=9–10, ribs/mm 4 th wh. =10–12. Remarks Fresh material from the type locality was not available. Wagner (1897: 45–46) described this species as a “variety” of gracile , and mentioned, next to the type locality, Korenica as its habitat. We analysed specimens from the vicinity of this locality (Plitvice), having the same shell morphology as the syntypes , with evident spots on the whorls and a thick lip ( Fig. 109A ), but it was not possible to analyse the female genital morphology because of the poor preservation. In Wagner’s collection, there are specimens from Gračac, HR (MIZPASW7041) and “Berg Crnopac”, HR (MIZPASW7042) identified as this taxon. We tentatively report fresh material from these localities, ca 60 km south of Plješevica as such. The female genital organs of the sample from Gračac show a “ patulum -like” morphology.
