Description

Shell small, diameter between 0.3 and 0.5 mm, planispiral, dull, with dark brown colour except that the aperture is whitish. Protoconch of 3/4 whorl, bearing one prominent cord limited externally by a deep canal and with two weaker small cords on its inner part. The whole surface is rough.
Teleoconch between 1 and 1 1/2 whorls, with prominent tubercles bordered near the periphery by one or two undulating striae and a prominent undulating cord. On the first whorl the number of tubercles ranges between 9 to 11. The periphery is slightly angularly prominent in the middle showing the growth striae which are present in the rest of the shell, and with very tiny spiral undulating striae .
Etymology. The specific name refers to the irregular sculpture of the surface of the shell.
