Vermeulen (1994)'s description
"shell white, approximately opaque. Whorls 3 1/4 - 3 1/2 (tuba not included); top whorls moderately oblique, hardly elevated; body whorls forming an cylindrical body, convex, well rounded, with the suture well impressed. Constriction inconspicuous, gradual. tuba consisting of approximately 1/4 whorl or slightly more, touching the body whorls over its entire length, approximately circular in section. Shell with rather thin radial ribs, which are densely placed near the top, densely placed and low on the upper body whorl (approximately 45-80 ribs present; ribs particularly close towards the top), approximately similar and only slightly wider spaced on the lower body whorl as well as over the area of the constriction, and densely placed again and somewhat more prominent on the tuba. Spiral striation absent. umbilicus open, deep, very narrow. Aperture with the imaginary plane through the inner peristome tilted 70-90 degrees with regard to the soiling axis of the body whorls; with the upper margin not protruding beyond the plane perpendicular to the soiling axis of the body whorls as well as through the apex; widely ovate to approximately circular; apertural teeth absent; inner peristome thickened, somewhat reflected; outer peristome moderately flaring on the palatal side. Constriction inside with one tooth: a rather inconspicuous, transverse, long, low palatalis; infracolumellaris absent. Measurements.-Height of body whorls 0.5-0.6 mm; width including tuba 1.0-1.1 mm, without tuba 0.7 mm; height of aperture 0.4 mm; width aperture 0.4 mm."
