Rughidia milleri

Unknown

Overview

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

Rughidia milleri faces significant pressure from habitat degradation in its limited cave and karst environments. Urban development and quarrying activities in limestone regions directly threaten the delicate underground ecosystems this harvestman depends upon. Water table changes from human activities can alter the humid microclimate conditions essential for its survival, while pollution from surface runoff may contaminate the pristine cave environments where small populations persist.

Threat summary

Habitat

This harvestman species inhabits limestone caves and associated karst formations, requiring stable humidity levels and specific microclimate conditions found in underground environments. It typically occurs in the twilight zones of caves where some natural light penetration creates optimal conditions for its specialized ecological niche.
