Material. 25 specimens from 10 samples.

Description. Test free, compressed, trochospirally coiled, trilobate in outline, elliptic and elongated in axial view or quadrilobate in ventral view, subelliptic in lateral view; 3-4 chambers in the last whorl increasing regularly in size covering the previous whorls. Chambers circular in outline, lenticular or subspheric with rounded periphery; sutures distinct, depressed. Aperture not distinguishable; wall smooth, finely agglutinated.

Distribution. Cosmopolitan species common from the Cretaceous to the Eocene ( Kaminski and Gradstein, 2005), less frequent in the Oligocene, and signaled in the Miocene ( Green et al., 2004; Kender et al., 2009).
