Epiglypta is a monotypic genus of glass snails that is endemic to Australia’s Lord Howe Island in the Tasman Sea.[1] The species is Epiglypta howeinsulae, also known as the ribbed glass snail; it has not been collected since 1920 and may be extinct due to rat predation.[3]
Description[edit]
The shell of adult snails is 17–21 mm in height, with a diameter of 31.9–34.8 mm, subglobose with a moderately raised spire, with rounded whorls, impressed sutures and closely spaced radial ribs. It is yellowish-brown in colouration. The umbilicus is narrowly open in juveniles, closed by reflection in adults. The aperture is ovately lunate. It is identifiable by its large and distinctly ribbed shell.[3]
Distribution and habitat[edit]
The snail's distribution was limited to the vicinity of the summits of the southern mountains of the island, where it was found beneath stones and on wet rock faces.[3]
