Whorls convex, rounded or slightly angular because of the presence of strong spiral threads, somewhat flattened below the lowermost spiral thread, sometimes somewhat flattened above the upper spiral thread. Protoconch whorls convex; sculpture: (1-)4-6(-9) inconspicuous to distinct, thin spiral threads; radial sculpture absent or some subordinate wrinkles. Teleoconch: Last whorl with (2-)3(-4) distinct, narrow spiral threads (when 2: 1 above and 1 below the periphery; when 3-4: 1 at the periphery, 1 well below, and 1-2 above), the lowermost coinciding with the suture of the penultimate whorl; between the spiral threads often (traces of) a fine, rather dense to moderately spaced spiral striation; below the lowermost spiral thread a similar moderately to widely spaced spiral striation which gradually disappears towards the umbilicus. Radial sculpture most distinct below the suture: fine growth lines, locally grading into somewhat spaced riblets. Umbilicus open, narrow. Dimensions: Height up to 3.2 mm; width up to 3.5 mm; diameters of the first four whorls 0.6-0.8 mm, 1.0-1.3 mm, 1.6-2.0 mm, 2.1-2.7 mm respectively; number of whorls up to 5 1/2; height aperture up to 1.1 mm; width aperture up to 1.6 mm.</paragraph>

(Leschke), from Java, has a comparable size and mode of coiling (diameter of the first four whorls c. 0.6 mm, 1.1 mm, 1.6 mm, 2.4 mm respectively). It differs by having flattened protoconch whorls without spiral sculpture.

(Stoliczka), from Peninsular Malaysia, is of similar shape, but smaller (height up to 2 mm, and width up to 2.1 mm, at 5 3/8 whorls). It is also more densely coiled (diameter of the first four whorls 0.4-0.5 mm, 0.70-0.85 mm, 1.05-1.20 mm, 1.4-1.6 mm respectively).
