Abstract

Olianatrivia riberai n. gen., n. sp. (Mollusca, Caenogastropoda), a singular Ovulidae from the Bartonian (middle Eocene) of Catalonia (Spain).

Shells of an Ovulidae species with unusual morphological features have been collected in the axial part of the Oliana anticline, Catalonia: Olianatrivia riberai n. gen., n. sp. (Mollusca, Caenogastropoda) whose shape and ornamentation remind some Triviinae. According to the chronostratigraphy of the South-Pyrenean basin, it belongs to a subrecifal facies, reworked by storm dynamics, of a Late Bartonian age (Middle Eocene). It is proposed to place O. riberai n. gen., n. sp. within the Pediculariinae, a subfamily of Ovulidae (Cypraeoidea), close to Cypropterina ceciliae (De Gregorio, 1880) from the Veronese Early Lutetian.
