Shell. Cylindrical-conic; dextral; with apex not abruptly pointed; with the most swollen part occurred at penultimate whorl or body whorl; height 12.4, diameter major 3.9, ratio of shell height /diameter major 3.17. Growth lines usually not very clear. Whorls 9 5/8, slightly convex. Embryonic shell 1 5/8 whorls. Postnuclear whorls smooth. Suture simple. Last whorl ascending immediately near aperture; more or less straight at periphery; with a rugate region with abapertural crowded and/or thickened growthline-like folds. Aperture not duplicate; wavy; ovate; quite oblique; completely attached to body whorl; height 3.3, width 2.8, ratio of shell height /apertural height 3.71. Peristome and parietal callus almost completely fusing except for a channel at upper insertion of peristome. Reflexed part of peristome straight and not curved backward. Abapertural peripheral depression on body whorl spirally extending for ca. 1 whorl. Columella with 2 teeth. Columellar margin reflexed. Columella oblique. Umbilicus widely open. Apex yellowish brown; subsequent whorls whitish. Aperture white. Measured specimen:SMF-42069: 1 shell.
