This species is characterized by its whitish shell adorned with dark, spiral bands that are uniform and spaced apart. Its genital system exhibits a very short penis and bursa copulatrix, as well as a spermoviduct with a wide, coiled uterus and a very narrow prostate, among other anatomical idiosyncrasies.
