Maro sublestus

Unknown

Overview

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

Maro sublestus faces significant pressure from habitat degradation in its specialized moss and lichen microhabitats within old-growth forests. Agricultural expansion and forestry practices have reduced the availability of suitable substrates, while climate change alters the moisture regimes essential for the bryophyte communities this spider depends upon. Urban development in coastal regions has further fragmented remaining populations.

Threat summary

Habitat

This small spider inhabits moss and lichen communities on tree bark and rocks in humid, old-growth forests and woodland edges. It requires stable moisture conditions and undisturbed bryophyte substrates for successful reproduction and prey capture.
