Roncus lubricus

Unknown

Overview

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

The Reddish Two-eyed Chelifer faces significant threats from habitat degradation in its specialized cave and underground environments. Human activities including quarrying, construction, and groundwater extraction directly impact the delicate subterranean ecosystems this pseudoscorpion depends upon. Climate change poses additional risks through altered groundwater levels and temperature fluctuations that can disrupt the stable conditions required for cave-dwelling invertebrates.

Threat summary

Habitat

This species inhabits cave systems and underground environments, particularly in limestone karst regions where it occupies humid microhabitats within rock crevices and cave passages. It requires stable temperature and humidity conditions typical of deep cave zones, often found in association with organic debris and small invertebrate prey.
