Overview

Gnaphosa lucifuga is a ground spider species with Palearctic distribution.

Gnaphosa lucifuga faces severe population declines due to habitat destruction and degradation of its specialized cave and underground environments. Human activities including cave disturbance, mining operations, and groundwater pollution have significantly reduced available habitat, while the species' limited dispersal ability makes population recovery extremely difficult.

Threat summary

Habitat

This species inhabits caves, underground cavities, cellars, and other dark subterranean environments, typically in areas with stable temperature and humidity conditions. It shows a strong preference for deep cave zones and artificial underground structures that mimic natural cave conditions.

sorgnattedderkopp is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Gnaphosa lucifuga faces severe population declines due to habitat destruction and degradation of its specialized cave and underground environments. Human activities including cave disturbance, mining operations, and groundwater pollution have significantly reduced available habitat, while the species' limited dispersal ability makes population recovery extremely difficult.
Where does sorgnattedderkopp live?
sorgnattedderkopp occurs in Afghanistan, Austria, Belgium, Bosnia & Herzegovina, Bulgaria, and Czechia (plus 18 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to sorgnattedderkopp?
The main threats to sorgnattedderkopp are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
