Koilodepas calycinum

Unknown

Overview

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

Koilodepas calycinum faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and infrastructure development further compound these pressures, while climate change threatens to alter the specific microhabitat conditions this endemic species requires.

Threat summary

Habitat

Koilodepas calycinum inhabits lowland and montane tropical rainforests, typically found in areas with high humidity and stable temperatures. The species shows preference for undisturbed primary forest environments with dense canopy cover and rich organic soil layers.

Why is Koilodepas calycinum classified as Endangered?
Koilodepas calycinum 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. Koilodepas calycinum faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and infrastructure development further compound these pressures, while climate change threatens to alter the specific microhabitat conditions this endemic species requires.
Where does Koilodepas calycinum live?
Koilodepas calycinum occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Koilodepas calycinum?
The main threats to Koilodepas calycinum 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.
