Farqua quadrimaculata

Unknown

Overview

Farqua is a genus of spiders belonging to the family Oonopidae. It was first described in 2001 by Saaristo. As of 2017, the genus includes only one species, Farqua quadrimaculata, which is found on the Farquhar Group islands in the Seychelles.

Farqua quadrimaculata faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, with fragmented populations showing reduced genetic diversity and reproductive success.

Threat summary

Habitat

This species inhabits specialized microhabitats within tropical and subtropical ecosystems, typically requiring specific vegetation communities and moisture conditions.

Why is Farqua quadrimaculata classified as Critically Endangered?
Farqua quadrimaculata is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Farqua quadrimaculata faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, with fragmented populations showing reduced genetic diversity and reproductive success.
Where does Farqua quadrimaculata live?
Farqua quadrimaculata occurs in Seychelles. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Farqua quadrimaculata?
The main threats to Farqua quadrimaculata are 11.1, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
