Dimensions. Height of holotype 1.86 mm, breadth 1.28 mm.
Shell small, conical, fairly solid, colourless transparent, mainly with spi¬ral sculpture at the suture and base, with a large aperture and blunt apex. Larval shell depressed, dome-shaped, consisting of 1.5 weakly and evenly convex whorls, sculptured with a few scattered very small tubercles. Diameter 500 µm. Teleoconch with 2.2-2.3 rather flat whorls of ra¬pidly increasing diameter, sculptured with numerous, irregularly disposed incremental lines of varying strength and 1-3 canal-like furrows just below the suture and 5-8 additional, similar furrows at and below the level of the suture on the body-whorl, covering most of the basal area, but leaving the area close to the umbilical chink smooth. Aperture large, slightly expanded, somewhat squarish. Outer lip slightly thickened, inner lip reflected over an inconspicuous umbilical crevice.
