Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Nothophantes horridus faces severe threats from habitat destruction due to quarrying and limestone extraction activities in its restricted cave systems. The species' extremely limited distribution makes it particularly vulnerable to any disturbance of its underground environment. Climate change poses additional risks through altered groundwater levels and temperature fluctuations that could disrupt the delicate cave ecosystem this spider depends upon.
Habitat
This critically endangered spider inhabits deep limestone cave systems and underground cavities. It requires stable, humid cave environments with consistent temperatures and undisturbed substrate conditions.
