Valvata heidemariae bicarinata Willmann, 1981: 158, textfigs 56 D-F [non Valvata bicarinata Lea, 1841]. Etymology. In honor of Rainer Willmann (University of Kiel), who intensively studied the Plio-Pleistocene deposits and freshwater mollusks of Greece. Type locality. Vokasia Valley 3 km SE of Kos City, Kos Island, Greece. Age. Early Pleistocene (Middle Irakli Formation). Type material. Geological-Paleontological Institute, University of Kiel, no number indicated; Willmann (1981 , textfigs 56 D-E ). Discussion. The species-group name bicarinata in combination with Valvata is preoccupied by the Recent species Valvata bicarinata Lea, 1841 from Pennsylvania, USA. The taxonomic separation from Valvata heidemariae Willmann, 1981 seems plausible, given the presence of a strong median keel on the upper whorl surface that is lacking in the nominal species.
