Description

The ear-shaped shell of mature snails is 7.1–8.3 mm in height, with a diameter of 15.6–17.7 mm, discoidal with a flat spire and impressed sutures. It is dark reddish-brown with indistinct zigzag, cream-coloured flammulations (flame-like markings). The umbilicus is moderately wide. The ovately lunate aperture is flattened on the upper edge. The animal has a lime-green sole and dark grey upper body, neck, head and eye-tentacles. [2]

Habitat

The snail is known mainly from the summits and upper slopes of Mount Lidgbird and Mount Gower, living in rainforest leaf litter. [2]

Conservation

The snail has been subject to predation by introduced rodents and is considered to be Critically Endangered. [2]
