Pistius truncatus

Local name: Thomise tronqué

Unknown

Overview

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

Pistius truncatus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its Mediterranean range. The species' specialized microhabitat requirements make it particularly vulnerable to landscape fragmentation, while climate change is altering the moisture and temperature conditions essential for its survival. Pesticide use in agricultural areas poses an additional threat through both direct toxicity and reduction of prey species.

Threat summary

Habitat

This crab spider inhabits Mediterranean scrubland, rocky outcrops, and semi-arid grasslands, typically found on low vegetation and under stones in areas with specific moisture and temperature regimes. The species shows preference for undisturbed habitats with diverse plant communities that support its arthropod prey base.
