Description

edit

The shell of the snail is 3.3–4.2 mm in height, with a diameter of 7.4–8.1 mm. The colour is dark reddish-brown with zigzagging cream flammulations (flame-like markings). The shape is discoidal with a flat to slightly sunken spire, rounded whorls, impressed sutures, and with moderately closely-spaced radial ribs. The umbilicus is widely open. The aperture is roundly lunate with a flattened upper edge. The animal is cream to pale grey, with a pink head, dark grey to black eyestalks, and with two dark bands along the neck.[1]

Distribution and habitat

edit

The snail is common and widespread in the lowlands of the island, where it is found in moist woodland and rainforest, in plant litter beneath logs and fallen palm fronds.[1]
