Description

The diameter of the shell attains 32 mm.

The shell displays a markedly wide umbilicus, presenting a solid structure. It is intricately marked with closely spaced rugose striations, imparting a radiant fulvous horn-like appearance, accentuated by a delicate white peripheral line. The shell shows eight flattened whorls that gradually increase in size. The body whorl barely projects forward. The shell's periphery adopts a subtly angular form. Its peristome, thin and whitish, elegantly reflects outward.^[2]
