Semilaoma laevis, also known as the smooth pinhead snail, is a tiny species of land snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.[2]

Description[edit]

The depressedly turbinate shell of the mature snail is 0.7–0.8 mm in height, with a diameter of 1.2–1.3 mm, and a low spire. It is pale yellow to white in colour. The whorls are rounded. The sutures are impressed, with closely-spaced radial ribs. It has a roundly lunate aperture, and a narrowly open umbilicus. The animal is unknown.[2]

Distribution and habitat[edit]

The snail is common and widespread across the island, living in lowland forest, rainforest and scrub.[2]
