This species has an elongate, nearly straight-sided shell that is glossy and translucent (Kerney and Cameron, 1979). The lip of the aperture is simple, the umbilicus is perforate. The live animal is pale yellow. The shell is smaller than the very-similar A. mauritianum and its spire is wider than A. gracile (Pilsbry, 1906 in Malay Peninsular Terrestrial Molluscs, 2017).

In Malaysia, Allopeas clavulinum is a litter-dwelling species, living among stones, leaves, grass and soil, from 300 to 2000 m altitude (Benthem-Jutting, 1952 in Malay Peninsular Terrestrial Molluscs, 2017).
Taxonomy
Also known as Lamellaxis clavulinus. Some authors have synonymized this species within A. mauritianum.
