The discoidal shell of the mature snail is 1.8–2.1 mm in height, with a diameter of 3.7–4.1 mm, and a flat or slightly raised spire. It is smooth, glossy and dark amber-brown in colour in live animals, the empty shell being golden-brown. The whorls are rounded, with flat sutures and finely incised spiral grooves. It has an ovately lunate aperture and closed umbilicus. The animal is dark grey with darker eyestalks.[2]
Distribution and habitat
The snail has a patchy distribution across the island and is found in leaf litter and the axils of palms.[2]
