The depressedly trochoidal shell of the mature snail is 4.4–5.1 mm in height, with a diameter of 6.9–8.1 mm, golden-brown in colour. The whorls are flattened above and rounded below an angular periphery, with weakly impressed sutures and strong radial growth lines. It has an ovately lunate aperture and closed umbilicus. The animal is black.^[2]

Distribution and habitat

The snail is rare and known only from the summit and upper slopes of Mount Lidgbird, where it is found on basalt rocks.^[2]
