Description
The length of the shell attains 2.5 mm, its diameter 1 mm.The very small, white shell has an ovate-fusiform shape. It contains nine whorls. The apical whorls are almost caudate, three to four of almost uniform narrow build, quite smooth and glossy. The remainder are uniformly acutely keeled. The aperture is round. The thickened peristome with a squarish extension of the columellar base, half hides the narrow umbilicus.
In sculpture it shows kinship with Aclis ascaris.
