Protoconch 2-2 1/8 whorls, smooth. Teleoconch. Radial sculpture: above and below the periphery scattered inconspicuous growth lines, locally grading into inconspicuous riblets; next to this a very fine (just visible at 40 times magnification) radial wrinkling of the shell surface is locally present. Spiral sculpture: last whorl with a sharp, slightly pinched peripheral ridge; start of fifth whorl with 19-23 somewhat spaced, low and thin spiral threads, the 2-5 threads close to the periphery slightly more distinct, the others inconspicuous; no spiral sculpture below the periphery. Umbilicus closed. Peristome thickened and reflexed, basal edge more or less evenly rounded from the columellar side to the periphery. Dimensions: Height 6.0-8.5 mm; width 13.5-18.0 mm; h/w 0.39-0.45; peripheral keel of the last whorl at 0.33-0.40 of the shell height, measured from the apex; diameters of the first 4 whorls 1.3-1.4 mm, 2.2-2.3 mm, 3.7-4.0 mm, 5.9-6.4 mm respectively; number of whorls 6-7 1/8, height aperture 3.5-5.2 mm; width aperture 7.0-10.0 mm. Shell medium-sized, thin, about opaque, uniformly pale yellowish brown.
