Paralaoma morti, also known as Mort's pinhead snail, is a species of land snail that is found on Australia's Lord Howe Island in the Tasman Sea.[2]

Taxonomy[edit]

This species is sometimes considered to be a synonym of P. caputspinulae or of P. servilis.[2]

Description[edit]

The depressedly turbinate shell of the mature snail is 1.1–1.3 mm in height, with a diameter of 1.7–2.4 mm, and a low spire. It is golden-brown in colour. The whorls are rounded and slightly shouldered, with impressed sutures and distinct, widely spaced radial ribs. It has a roundedly lunate aperture and widely open umbilicus.[2]

Distribution and habitat[edit]

The snail is common and widespread across the island.[2]
