Stomacosmethis balingensis

Declining

Overview

Stomacosmethis balingensis is a species of land snail with a gill and an operculum, a terrestrial gastropod mollusc in the family Alycaeidae.

Stomacosmethis balingensis faces severe threats from rapid deforestation and habitat conversion in its restricted montane forest range. Mining activities and agricultural expansion have fragmented the remaining suitable habitat, while climate change poses additional pressure on this high-altitude specialist. The species' extremely limited distribution makes it particularly vulnerable to local extinctions from even small-scale habitat disturbances.

Threat summary

Habitat

This species inhabits montane tropical forests at elevations between 1,200-1,800 meters in the Baling Hills region of Peninsular Malaysia. It requires intact primary forest canopy with specific microclimate conditions typical of highland rainforest ecosystems.
