(Original description in Latin) The shell features a barely visible fissure and has a fusiform, swollen shape with small ribs, broad in form, and a brownish-horn color. The aperture is wide and rounded-pyriform, with a swollen spire and a crested base. The peristome is continuous, with a solitary, reflexed, reddish edge. The lower lamella is set apart, and there are two upper palatal folds, with the lower posterior fold being very short. A crescent-shaped fold is incomplete, and the columellar fold is slightly submerged. The area surrounding the umbilicus is hemispherical. ^[1]
