Diplommatina alata

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Diplommatina alata faces severe threats from habitat destruction and fragmentation of its limestone cave systems. The species' extremely restricted range makes it particularly vulnerable to local disturbances, including quarrying activities and tourism development that can alter cave microclimates. Climate change poses additional risks through potential shifts in humidity and temperature regimes critical for this cave-dwelling gastropod's survival.

Threat summary

Habitat

This species inhabits limestone cave systems and karst formations, requiring specific humidity and temperature conditions found in these underground environments. It is typically associated with cave walls and rock crevices where calcium carbonate deposits provide both shelter and feeding opportunities.
