Carabdytes alutaceus

Unknown

Overview

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

Carabdytes alutaceus faces severe threats from groundwater extraction and aquifer depletion, which directly impacts the water table levels essential for its survival in subterranean habitats. Agricultural intensification and urban development above its cave systems have led to contamination of groundwater through pesticide runoff and sewage infiltration. The species' extremely limited distribution makes it particularly vulnerable to localized environmental changes, with entire populations at risk from single pollution events or hydrological alterations.

Threat summary

Habitat

This subterranean beetle inhabits groundwater-fed cave systems and underground aquifers in limestone karst formations. It requires stable water tables and clean groundwater environments, typically found in deep cave pools and underground streams with consistent temperatures and minimal light penetration.

Frequently asked questions

Why is Carabdytes alutaceus classified as Endangered?
Carabdytes alutaceus is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Carabdytes alutaceus faces severe threats from groundwater extraction and aquifer depletion, which directly impacts the water table levels essential for its survival in subterranean habitats. Agricultural intensification and urban development above its cave systems have led to contamination of groundwater through pesticide runoff and sewage infiltration. The species' extremely limited distribution makes it particularly vulnerable to localized environmental changes, with entire populations at risk from single pollution events or hydrological alterations.
Where does Carabdytes alutaceus live?
Carabdytes alutaceus occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
