Shell narrow (length:width ratio 2.8-3.9), sides of last whorl rather weakly convex; outer lip strongly arched in side view but not forming a notch below suture; sculpture of fine, curved axial riblets (or coarse growth-lines), with a minute spiral thread under suture on later whorls. Transparent yellowish, often with a brown line below the suture. Length up to 8.0 mm.
Found mainly in the KwaZulu-Natal Midlands, from Bulwer to Pietermaritzburg and Fort Nottingham, other records require confirmation. Inhabits leaf-litter in mist-belt Podocarpus forest.
Narrower specimens from Pietermaritzburg and Dargle were described as a distinct species, Opeas fanei Connolly, 1919, which was said to differ from typical O. strigile in having a higher spire, slightly less convex whorls and weaker sculpture. However, we are unable to consistently differentiate the two (Henry Burnup had a similar problem).
