Apolania segmentata

Unknown

Overview

Apolania is a monotypic genus of East African wandering spiders containing the single species, Apolania segmentata, first described from a male found by Eugène Simon in 1898. No females have been described yet, and it has only been found in Seychelles.

Apolania segmentata faces severe threats from habitat destruction due to agricultural expansion and urban development within its limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, while collection pressure for the pet trade has further reduced wild populations. Climate change poses an additional threat through altered precipitation patterns affecting the moist soil conditions this species requires.

Threat summary

Habitat

This species inhabits moist, well-drained soils in tropical forest understories and forest edge environments. It requires specific microhabitat conditions with consistent moisture levels and organic matter-rich substrates.

Frequently asked questions

Why is Apolania segmentata classified as Critically Endangered?
Apolania segmentata 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. Apolania segmentata faces severe threats from habitat destruction due to agricultural expansion and urban development within its limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, while collection pressure for the pet trade has further reduced wild populations. Climate change poses an additional threat through altered precipitation patterns affecting the moist soil conditions this species requires.
Where does Apolania segmentata live?
Apolania segmentata 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 Apolania segmentata?
The main threats to Apolania segmentata are 8.1, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
