Distribution

Geomitra coronula is endemic to the Madeira Archipelago, where it is only found on the Desertas Islands. It was originally described by English malacologist Richard Thomas Lowe in 1852, from Quaternary fossil deposits found in the southern part of Bugio Island.

It has a conical white shell, 5–6 mm (0.20–0.24 in) in width and 3.5–4.5 mm (0.14–0.18 in) in length, with five whorls.^[1]
