Melloconcha rosacea, also known as the tiny rosy glass-snail, is a species of land snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.^[2]

Description

The discoidal shell of the mature snail is 1.8–2.1 mm in height, with a diameter of 3.7–4.1 mm, and a flat or slightly raised spire. It is smooth, glossy and dark amber-brown in colour in live animals, the empty shell being golden-brown. The whorls are rounded, with flat sutures and finely incised spiral grooves. It has an ovately lunate aperture and closed umbilicus. The animal is dark grey with darker eyestalks.^[2]

Distribution and habitat

The snail has a patchy distribution across the island and is found in leaf litter and the axils of palms.^[2]
