Characterization. Shell with flattened apex and inflated base; H 0.80 mm, W 1.04 mm; P with axial sculpture, DN 0.06–0.09 mm; T 1 with strong prosocline axial lamellae and fine spiral cords; axial lamellae weaker on T 2; aperture large, inclined; umbilical wall straight; umbilical ridge thin but prominent.
