Description
The shell is glassy and translucent, with a dotted and sometimes striped spiral structure, and reaches a length of 2 mm. The columellar fold is almost absent and the inner edge of the columella is folded over the umbilical rim.[3] Monterosato wrote of it consisting of "3 ½ recesses, descending, compressed, finely striated" and the original publication of the species described them as "elegant and rare shells."[3] It is most likely a simultaneous hermaphrodite.[4]
