Oak-tree Chelifer

Larca lata

Unknown

Overview

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

The Oak-tree Chelifer faces severe habitat loss due to deforestation and fragmentation of oak woodlands across its range. Urban development and agricultural expansion have eliminated many suitable oak groves, while climate change threatens the specific microhabitat conditions this pseudoscorpion requires. The species' dependence on mature oak bark crevices makes it particularly vulnerable to forest management practices that remove older trees.

Threat summary

Habitat

This pseudoscorpion inhabits the bark crevices and under loose bark of mature oak trees, particularly in old-growth and semi-natural oak woodlands. It requires specific moisture and temperature conditions found in the microhabitat between bark layers of living oak trees.
