==Description==
The slender, white to transparent shell has a nearly cylindrical shape with an obtuse apex. Its length measures 1.7 mm. The whorls of the protoconch are intorted. The teleoconch contains 3½ rounded whorls. The suture is well marked. The growthlines are somewhat prosocline (i.e. with the growth lines leaning forward (adapically) with respect to the direction of the cone) and not strongly marked. The sculpture of the surface is smooth and shiny. The outer lip is thin. There is no umbilicus. The columellar tooth is weak and is deeply seated inside the pyriform aperture.〔 ( J.J. van Aartsen, E.
