Troglohyphantes gracilis

Unknown

Overview

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

Troglohyphantes gracilis faces significant threats from cave disturbance and habitat degradation in its limited subterranean range. Human activities including speleology, cave tourism, and infrastructure development near cave systems pose direct risks to this specialized cave-dwelling spider. The species' extremely restricted distribution and dependence on stable cave microclimates make it particularly vulnerable to environmental changes and direct habitat modification.

Threat summary

Habitat

This species inhabits deep cave systems and underground cavities in limestone karst regions. It occupies the stable, humid zones of caves where it constructs webs to capture small invertebrate prey in the perpetually dark subterranean environment.
