(original description) The height of the shell varies between 1.59 mm and 1.89 mm, its diameter between 1.91 mm and 2.38 mm. The shell is minute and triangular in shape, featuring a high
spire and a brownish coloration. Both the
protoconch and the
teleoconch are smooth. The
body whorl is characterized by a broad sulcus (groove), while the tuba (the final part of the body whorl when it becomes detached from the previous whorls) remains very short. Unlike related species, the
peristome is not expanded, and the
aperture lacks teeth entirely. ==Distribution==
