Protoconch unknown. Teleoconch whorls flat, separated by narrow suture located immediately abapical to keel ridge. Wide and low varices scattered unevenly on spire, the last occurring approximately opposite aperture on last whorl. Keel carrying two sharply developed ridges, adapical one only visible on last whorl. Base flattened. Aperture relatively small, strongly rounded adaxially against only slightly convex columella; inner lip well developed with strong parietal ridge forming continuation of abapical keel ridge. Columellar fold absent. Teleoconch sculpture on younger whorls consisting of weak transverse ribs crossed by spiral lirae, forming up to five weak, beaded spiral ribs. Adult teleoconch whorls nearly smooth but for fine spiral lirae and a weak spiral band of 40 to 50 tubercles per whorl adjacent to adapical suture. Growth lines slightly opisthocyrt, forming very fine and dense pattern on whorl surface, on adapical keel ridge developing into very fine and dense beading. Base covered by spiral ribs of unequal strength.
