The 0.6-0.8 x 1.2-1.6 mm shell is almost flat, extremely densely and regularly striated, appearing silky shiny light horny brown. There are 3-3.5 moderately convex whorls, the aperture is rounded, with a thin margin which is not reflected and without a lip. The umbilicus is wide (25% of shell diameter).[2]
