Esu, Daniela; Girotti, Odoardo
A late Early Pleistocene non-marine molluscan fauna from the Synania Formation (Achaia, Greece) is reported here. The fauna is well diversified including at least twenty-six species among freshwater and oligohaline gastropods and bivalves. Nine gastropods turned out to be new: Theodoxus patrae n. sp., Melanopsis synaniae n. sp., ? Goniochilus achaiae n. sp., Tournouerina ronaldi n. sp., ? Islamia corinthica n. sp., ? Pyrgula danielae Girotti n. sp., Pyrgula nikosi n. sp., Lithoglyphus marci n. sp., and Valvata pyramidula n. sp. On the whole, the studied fauna is characterized by a high degree (about 80%) of extinct taxa, which show strong endemic character and Early Pleistocene affinity.
