Belongs within: Loeblichiidae.

Characters (Cózar & Vachard 2001): Coiling entirely aligned, except a weak early deviation, with expansion rate of spire slow and progressive. Numerous chambers at last whorl (16–20), all quadratic and with faintly depressed sutures. Septa enlarged in juvenile part of shell, not always at adult stage. Septa perpendicular to wall, or slightly inclined toward aperture. Chomata weakly to rather developed. Wall microgranular, not differentiated.
