Philosina alba

Unknown

Overview

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

Philosina alba faces significant pressure from habitat degradation in its restricted range of limestone karst formations. Agricultural expansion and quarrying activities have fragmented its specialized cave and rock crevice habitats. The species' limited dispersal ability and dependence on specific microclimate conditions make populations particularly vulnerable to environmental changes and human disturbance.
