Abstract
A new species of the foraminiferal genus Pseudorhapydionina is reported from the Santonian shallow-water carbonate and mixed deposits of La Cova Unit, in the Montsec and Pedraforca thrust sheets (Southern Pyrenees, NE Spain). Pseudorhapydionina bilottei sp. nov. differs from the Cenomanian species of the genus in its larger test size and the number of chambers in its early planispiral-involute stage. The discovery of P. bilottei sp. nov in the Santonian indicates that the genus Pseudorhapydionina escaped extinction during the Cenomanian-Turonian boundary (CTB) event in the Pyrenean bioprovince. A new subfamily Pseudorhapydionininae is described.
