Lirceus usdagalun

Unknown

Overview

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

Lirceus usdagalun faces severe threats from groundwater contamination and aquifer depletion in its limited cave habitat range. Agricultural runoff and urban development have degraded water quality in the karst systems where this endemic isopod survives. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes, with entire populations at risk from single contamination events.

Threat summary

Habitat

This endemic isopod inhabits groundwater systems and cave streams within karst limestone formations. It requires clean, oxygen-rich subterranean waters with stable temperatures and specific mineral compositions typical of southeastern United States cave ecosystems.
