Lampadia webbiana

Lampadia webbiana is a species of land snail in the family Helicidae, the true snails. It is endemic to Madeira.

This snail is native to Porto Santo, one of the islands of Madeira. It has also been found on the nearby islet Ilhéu de Cima, but this population has not been relocated and may be extirpated. On Porto Santo it is known only from three hills on the eastern side of the island, where it lives under rocks in grassy areas.

This species is threatened by introduced rodent predators, and possibly by degradation of its grassland habitat related to increasing tourism activity.
