Descrição original:

(Pilsbry, 1956): “The shell is somewhat wider than high, openly umbilicate, the periphery carinate. The first 1% whorls are smooth, strongly convex, forming a short, obtuse apical nipple. The following whorl is less convex, and the third whorl becomes flattened and carinate, the keel projecting above the suture. The last whorl has a flat, horizontal upper surface and strongly expressed peripheral keel; the somewhat convex lateral outline slopes inward anteriorly, and the base is strongly angular around the ample, funnel-shaped umbilicus. The aperture is sub triangular; peristome simple.”
