Location of Lord Howe Island |
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]
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]
The snail is common and widespread across the island, living in lowland forest, rainforest and scrub. [2]
