Colchester Spiny-backed Spider

Chumma inquieta

Declining

Overview

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

Chumma inquieta faces significant pressure from habitat degradation in its restricted range within the Western Ghats biodiversity hotspot. Deforestation for agricultural expansion and human settlement development has fragmented its forest habitat, while climate change threatens to alter the specific microhabitat conditions this species requires. The species' limited dispersal ability makes it particularly vulnerable to habitat fragmentation and edge effects.

Threat summary

Habitat

This species inhabits moist deciduous and semi-evergreen forests of the Western Ghats, typically found in leaf litter and understory vegetation at elevations between 400-1200 meters. It requires specific microhabitat conditions with high humidity and dense canopy cover.
