Description.

Shell small, rather thin, somewhat translucent or opaque, (pale) yellow-corneous to brown-corneous, (somewhat depressed) conical with convex sides; apex broadly rounded. Surface glossy or shiny. Whorls moderately convex, the last whorl more or less angular at the periphery, rounded above, rounded to almost flat below the periphery. Protoconch whorls convex, with spaced radial riblets and usually subordinate (sometimes equally distinct), very fine spiral grooves; usually these are reduced to spiral rows of minute, shallow identations; often the protoconch is almost smooth. Teleoconch: Last whorl with a peripheral spiral thread coinciding with the suture of the penultimate whorl, above this with very fine, inconspicuous, densely and regularly placed radial riblets locally, or with a few growth lines only; with or without traces of very fine, inconspicuous spiral striation, below the periphery usually with numerous fine, moderately and regularly spaced, continuous spiral grooves which are most distinct towards the periphery. Umbilicus open, narrow. Dimensions: Height up to 2.8 mm; width up to 3.2 mm; diameters of the first four whorls 0.5-0.8 mm, 0.90-1.35 mm, 1.5-2.0 mm, 2.0-2.8 mm respectively; number of whorls up to 5; height aperture up to 1.2 mm; width aperture up to 1.6 mm.

Habitat in Sabah and distribution.

Primary and secondary forest on limestone, sandstone and volcanic soil, up to 1400 m alt. Sabah: widespread. Also in Kalimantan. Endemic to Borneo.

Cross diagnosis.

Adult or nearly adult shells differ from Kaliella barrakporensis by the lower conical spire with more convex sides and a more broadly rounded apex. Usually, the sculpture is less distinct than in Kaliella barrakporensis , and the shells are glossier. Juveniles of both species are sometimes difficult to keep apart.
