Diagnosis Test narrow, elongate, chambers one-half coil in length, early chambers in quinqueloculine arrangement, then planispiral or with planes slightly more than 180¡ apart to result in a sigmoid appearance in section, chambers strongly produced at the aperture, resulting in a very elongate test; wall calcareous, porcelaneous, surface smooth to coarsely costate; aperture terminal at the end of the elongate neck, ovate to slitlike, without a tooth. M. Miocene; USSR: N. Caucasus, Azerbaydzhan, Georgia, Dagestan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
