Dignamoconcha is a monotypic genus of pinhead or dot snails that is endemic to Australia's Lord Howe Island in the Tasman Sea.[2]
The trochoidal shell of the mature snail is 3.3 mm in height, with a diameter of 5.7 mm, with a stepped, pagoda-like spire. It is pale golden-brown in colour, with white radial streaks. The whorl profile is flattened above and below a strongly keeled periphery. It has a diamond-shaped aperture and widely open umbilicus. It is the largest known punctid in Australia.[2]
Although the snail is sometimes reported from other sites on the island, its main area of occurrence is on the slopes of the southern mountains, at altitudes of 200–600 m in rainforest, where it is arboreal and found on the undersides of green leaves, especially those of palms.[2]
