The spire has a convex-conical shape, ending in a pale apex. There are 5 somewhat convex whorls, with the body whorl deflected at the front and slightly flattened at the base. The columella is short and thread-like, ending at the base with a small denticle and emitting a thin callus. The aperture is oblique and somewhat triangular-semioval. The peristome is thin, with the right margin simple at the top, then dilated and expanded, featuring a distinct sinus at the base separated from the columellar tooth.[2]
