Parosphromenus rubrimontis

Unknown

Overview

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

Parosphromenus rubrimontis faces severe habitat degradation from palm oil plantation expansion and logging activities across its limited range in Borneo's peat swamp forests. The species' specialized requirements for acidic, tannin-rich blackwater environments make it particularly vulnerable to water quality changes from agricultural runoff and forest conversion. Small, fragmented populations are increasingly isolated as connecting forest corridors are cleared for development.

Threat summary

Habitat

This species inhabits acidic peat swamp forests and blackwater streams in Borneo, preferring shallow, slow-moving waters with dense vegetation and high tannin content. It requires pristine forest environments with stable water chemistry and abundant leaf litter that creates the characteristic dark, acidic conditions.

Frequently asked questions

Why is Parosphromenus rubrimontis classified as Endangered?
Parosphromenus rubrimontis is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Parosphromenus rubrimontis faces severe habitat degradation from palm oil plantation expansion and logging activities across its limited range in Borneo's peat swamp forests. The species' specialized requirements for acidic, tannin-rich blackwater environments make it particularly vulnerable to water quality changes from agricultural runoff and forest conversion. Small, fragmented populations are increasingly isolated as connecting forest corridors are cleared for development.
Where does Parosphromenus rubrimontis live?
Parosphromenus rubrimontis occurs in Indonesia, Malaysia, and Thailand. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Parosphromenus rubrimontis?
The main threats to Parosphromenus rubrimontis are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
