Revision of the Mediterranean Pliocene Apiocypraea F.A. Schilder, 1925 (Gastropoda: Eocypraeidae) with special consideration of shells of the “Spungone” area, Romagna, Northern Italy

Abstract

The taxa of the Mediterranean Pliocene Apiocypraea are revised, with each species discussed and compared. The type specimens are figured and discussed. The intraspecific variation is represented by additional figures and by tabulations of measurements, based especially on material from the "Spun-gone" area of Northern Italy. Apiocypraea cerretensis n. sp. is described from the Zanclean of Monte Cerreto, Romagna, Northern Italy. The neotype of Apiocypraea pyrula (Lamarck, 1810), which we also designate as the lectotype of Cypraea labrosa Sismonda, 1847, is a specimen in the Museo Civico di Storia Naturale di Milano. The lectotypes of Apiocypraea parvolonga (Sacco, 1894) and Apiocypraea parvoastensis (Sacco, 1894) designated here are both specimens in the Museo Regionale di Scienze Naturali di Torino.
