Description
The height of the shell reaches 1 mm. The shell has a heliciform shape. The thin spire is short, narrowly perforate, and semi-pellucid. It has a white color with a caducous rather thick pale olive epidermis. The spire consists of three whorls, the first ? (abrupt), the second a little convex, somewhat planulate above and radiately arcuately plicate. The body whorl is large, having a thin double carina (slit fasciole) a little above the middle, radiately arcuately plicate above the carina, below it with stride of growth. The large aperture is irregularly circular, and very slightly expanded at the basal margi. The peristome is continuous. The deep, narrow slit is situated between the two thread-like keels. (
