The discovery in the Spanish lower Pliocene of Moguer (Huelva, Spain), the Guadalquivir basin, of some valves corresponding to Lissochlamys excisa var. perstriatula Sacco, 1897 is reported. The comparison with the typical material preserved in the Natural History Museum of Turin (Italy) confirmed the correspondence between the Iberian and the Italian specimens. Due to the characteristics of the sculpture and the shape of the valves which clearly differentiate it from L. excisa (Bronn, 1831), this var. perstriatula is elevated to a valid species. |
