Gyropena is a genus of two species of tiny pinwheel snails that are endemic to Australia's Lord Howe Island in the Tasman Sea. [2]
The shells of these snails are 0.9–1.5 mm in height, with a diameter of 1.9–2.9 mm. The colour is golden-brown to pale fawn. The shape is discoidal with a low or sunken spire, whorls shouldered and sutures impressed, with prominent radial ribs. The umbilicus is widely open. The aperture is roundly lunate. [3]
These snails are found at the southern end of the island, on the summits and slopes of Mount Lidgbird and Mount Gower, in leaf litter. [3]
