in width, biconic in profile, composed of five whorls. Moderately high spire. Last whorl representing 72% of total height. Spiral angle 56°. Suture weakly impressed. Axial sculpture consisting in four slightly foliate varices per whorl. On spire, anal tube (P1) and very short spine (P2). Anal tube forming angle of approximately 60-65° with axis of shell. Anal tube (P1) totally integrated within varices, eliminating shoulder. Small callus at base of anal tube. On convex part of last whorl and abapically to anal tube four spinelets (P2, s2, P3, P4 and P5). Intervarical spaces usually smooth, but with P3-P5 cords on
