DistributionEdit

It is endemic to the Kinabatangan Valley, Sabah, Malaysia.[1] It lives in Borneo.[2]

Its natural habitat is lowland Dipterocarp rainforest. Opisthostoma mirabile is endemic to one limestone outcrop near Suan Lamba known as 'Gomanton Hill'.[3] Subpopulations existed in two smaller limestone outcrops. This species is absent in surrounding non-calcareous regions, and therefore restricted to 1.5 km2 of limestone hills.[1]

ThreatsEdit

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.[1]
