Leiostyla relevata
Leiostyla relevata is a species of small air-breathing land snail in the family Lauriidae. It is endemic to Ilhéu de Baixo, an islet near Porto Santo Island in the Madeira archipelago. This snail is only known from a single site on the wet seaside cliffs of the islet. The population, though small, is likely stable because the island is isolated from most threats. References
