Dignamoconcha is a monotypic genus of pinhead or dot snails that is endemic to Australia's Lord Howe Island in the Tasman Sea.

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.

[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.
