Abstract
- Freshwater ostracod assemblages from San Demetrio Synthem (L'Aquila Basin, central Apennines, Italy), dating back to the late Piacenzian–Gelasian, are studied. Six genera and eight species are recognised, six of which are new:Caspiocypris amiterniSpadi & Gliozzi sp. nov.,C. bosiiSpadi & Gliozzi sp. nov.,C. nicandroiSpadi & Gliozzi sp. nov.,C. vestinaeSpadi & Gliozzi sp. nov.,Cypria bikeratiaSpadi & Gliozzi sp. nov., andIlyocypris ilaeSpadi & Gliozzi sp. nov. Additionally, one fragmentary valve referred toParalimnocytherecf.P. dictyonalisMedici, Ceci & Gliozzi, 2011, one valve ascribed toAmnicythereex gr.stanchevaeKrstić, 1975, one fragment tentatively identified asLimnocythere? sp. and four poorly preserved valves of Cypridoidea indet. were also recovered. The genusCaspiocyprisis revised, and an emended diagnosis is provided. Comparisons are made with the most similar co-generic species occurring in the Neogene of Italy and the Paratethyan domain. The ostracod fauna of the San Demetrio Synthem shows the greatest affinity at the generic level with the Pontian (Messinian–Zanclean) ostracods of the Pannonic, Dacic and Euxinic Basins. To explain this affinity, two hypotheses are discussed: (1) passive dispersal of Paratethyan forms into the Italian Plio–Pleistocene palaeolakes; and (2) endemic evolution of several species in different Plio–Pleistocene palaeolakes from the Paratethyan-like late Messinian Lago-Mare ostracod fauna of the Palaeomediterranean area. http://zoobank.org/urn:lsid:zoobank.org:pub:881D73C7-E62E-460A-A465-363DAE20A8D5 [ABSTRACT FROM PUBLISHER]
