Shell small, rather thin, somewhat translucent, (pale) brown, sometimes white, rather low-conical with flat to slightly convex sides; apex rounded. Surface with a silky luster. Whorls moderately convex, last whorl rounded at the periphery (somewhat angular in juveniles), rounded above and below the periphery. Protoconch whorls convex, with numerous fine, rather densely placed radial riblets; spiral sculpture subordinate or approx. equally distinct, very fine (just visible at 40 times magnification), densely placed grooves. Teleoconch: above the periphery with fine, slightly spaced, nar row spiral grooves cutting into the crests of the radial riblets and subordinate to these; below the periphery slightly coarser and slightly more spaced spiral grooves. Radial sculpture: above the periphery fine, densely and regularly placed riblets; below the periphery with a few irregularly spaced, inconspicuous growth lines only. Umbilicus open, very narrow. Dimensions: Height up to 2.8 mm; width up to 3.65 mm; diameters of the first four whorls 0.6-0.7 mm, 1.05-1.30 mm, 1.6-1.9(-2.0) mm, 2.25-2.70(-3.0 mm) respectively; number of whorls up to c. 5 1/2; height aperture up to 0.7 mm; width aperture up to 1.2 mm. Radula: central 3-cuspid; laterals 3-cuspid; marginals 3-5 cuspid.

Habitat in Sabah and distribution.

Primary and secondary forest, coastal forest, at 0-1000 m alt, elsewhere to 2000 m alt. Sabah: widespread. Also in Sarawak; Kalimantan. Distribution elsewhere: Vietnam; Thailand; Peninsular Malaysia to Java; Eastwards to Australia, Pacific.


Samples from montane environments (e.g. Poring Hot Springs, V 13027 may include shells with a more loosely coiled spire than usual (diameter of the fourth whorl up to 3.0 mm; in other specimens 2.25-2.70 mm). In this character the shells approach Kaliella dendrobates   , but the sculpture is typical for Kaliella scandens   .

Information on the radula is from Rensch (1932). No Sabah material included in Kaliella scandens   has been checked for radula characters.
