Pilsbrycharopa tumida

Unknown

Overview

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

Pilsbrycharopa tumida faces significant threats from habitat degradation in its limited range within Hawaiian forest ecosystems. The species is particularly vulnerable to invasive plant species that alter the understory microhabitat conditions essential for this terrestrial gastropod. Agricultural expansion and urban development continue to fragment and reduce the native forest areas where this snail occurs, while introduced predators such as rats and non-native invertebrates pose additional pressure on remaining populations.

Threat summary

Habitat

This species inhabits native Hawaiian forest ecosystems, particularly in areas with dense leaf litter and appropriate moisture conditions. It occurs in both mesic and wet forest zones where the understory provides the specific microhabitat requirements needed for this terrestrial gastropod.
