The shell is rimate, oval, ventricose, nearly smooth, glossy, amber-brown or nearly chestnut, slightly transparent, outlines very convex. Whorls are rather convex, the last somewhat compressed below, with an impression over the lower palatal fold, a moderately developed, opaque crest behind the peristome; and a very deep impression between the crest and the point of the outer lip.[6]
Aperture having 6 principal and usually several smaller teeth: parietal lamella rather long; angular and infraparietal short and smaller. Columellar
lamella large, ascending inwardly. Upper and lower palatal folds strong, the lower longer. Basal fold stout, in a subcolumellar position. Usually there are small suprapalatal and infrapalatal denticles. Peristome is thin, a little expanded, the outer margin biarcuate, with a median entering angle. Palatal callus is well developed.[6]
The width of the adult shell varies from 1.2 to 1.4 mm, the height from 1.95 to 2.25 mm.[6]
