| Abstract |
The aim of this work is a review of the systematics of all Pholadinae from the Lower Paleogene. Except Cyrtopleuropsis lescailloni which is new, these species are currently assigned in the genus Barnea. However comparisons with Barnea and other genera of Pholadinae show distinctive morphological characters which permit to propose a new genus, Cyrtopleuropsis. Paleogene species are only know in Atlantic Ocean: for the Europe, Cyrtopleuropsis orbignyana (Lévesque in Graves, 1847), C. freyteti (Plaziat, 1970), C. lescailloni nov sp and for the United States, C. alatoidea (Aldrich, 1886). Stratigraphic distribution is given for all caenozoic Pholadinae. |
