Shell small, rather thin, somewhat translucent or opaque, (pale) brown-corneous, (somewhat elongated) conical with almost flat or slightly convex sides; apex narrowly rounded. Surface shiny or with a silky luster. Whorls moderately convex, the last whorl rounded to angular at the periphery, rounded above and below the periphery. Protoconch whorls convex, with spaced, inconspicuous radial riblets and usually subordinate, very fine spiral grooves; protoconch sometimes almost smooth. Teleoconch: Last whorl usually with a peripheral spiral thread coinciding with the suture of the penultimate whorl, above this with very fine, densely and regularly placed radial riblets, often only locally present, in some specimens virtually absent, and with or without traces of very fine (just visible at 40 times magnification), inconspicuous spiral striation; below the periphery usually with numerous fine, moderately and regularly spaced, continuous spiral grooves. Umbilicus open, narrow. Dimensions: Height up to 4.6 mm; width up to 4.3 mm; diameters of the first four whorls 0.65-0.80 mm, 1.10-1.25 mm, 1.5-2.0 mm, 2.15-2.70 mm respectively; number of whorls up to 6 1/2; height aperture up to 1.5 mm; width aperture up to 2.0 mm.

Habitat in Sabah and distribution.
