Hemicycla gomerensis (Morelet)

La Gomera Land Snail (Hemicycla gomerensis)

This species was described in 1864, it is or was endemic the the island of La Gomera, Canary Islands.

The shell reaches a size of about 2,1 cm in diameter.

In proportion to its size the shell is extremely thin and fragile, being more than usually sub-diaphanous when held up to the light; and its colour is a deep castaneous-brwon, but rather paler (or more olivaceous) beneath, with extremely indistinct indications of three obsolete darker bands, – one of which is just below the dorsal line, another immediately above it, and the third a little behind the suture (the space between this last one and the suture being sometimes, apparently, though not in the specimens now before me, of a more lively ochreous yellow).” [1]


The La Gomera Snail is listed in the Red List of the IUCN as ‘data deficient’, but may be already extinct.
