Description. Shell to 4.7 mm, trochiform biconical; spiral cords or carinated cords, ~6 stronger ones on shoulder, ~15 weaker ones on base; faint axial sculpture predominantly on early whorls, umbilicus open, no periumbilical cord, no funiculus; columellar wall somewhat thickened, aperture subquadratic.
