Description
The trochoidal shell of the mature snail is 2.1–2.5 mm in height, with a diameter of 3.2–3.5 mm, and a raised spire. It is cream to pale golden-brown in colour. The whorls are rounded and flattened below an angular periphery, with moderately spaced radial ribs. It has a roundedly lunate aperture, flattened on the upper side by a reflected lip, and a moderately wide umbilicus.[2]
Distribution and habitat
The snail is commonest in the settlement area of the island's lowlands, inhabiting plant litter in mixed forest.[2]
