Opisthostoma mirabile is a species of air-breathing land snail with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae.

[2] Its natural habitat is lowland Dipterocarp rainforest.

Opisthostoma mirabile is endemic to one limestone outcrop near Suan Lamba known as 'Gomanton Hill'.

This species is absent in surrounding non-calcareous regions, and therefore restricted to 1.5 km2 of limestone hills.

[1] It is threatened by habitat loss- limestone quarrying has extirpated Opisthostoma mirabile from the two lesser outcrops, and fire near the outcrops has caused forest desiccation which has led to a decline in Prosobranch populations.
