Kobo Bubble-nest Frog

Philautus microdiscus

Declining

Overview

Philautus microdiscus is a species of frog in the family Rhacophoridae. It is endemic to India, only known from Abor Hills in Arunachal Pradesh. This little-known species inhabits tropical moist lowland forests.

Philautus microdiscus faces severe population decline primarily due to rapid deforestation and habitat conversion in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to localized habitat destruction from agricultural expansion and infrastructure development. Climate change poses an additional threat by altering the cool, humid microclimate conditions essential for this small tree frog's survival and reproduction.

Threat summary

Habitat

This species inhabits cool, humid montane forests at elevations typically between 1,000-2,000 meters, where it depends on dense canopy cover and leaf litter microhabitats. It requires pristine forest conditions with stable moisture levels and is particularly associated with areas near streams or other water sources for breeding.

Frequently asked questions

Why is Kobo Bubble-nest Frog classified as Critically Endangered?
Kobo Bubble-nest Frog 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. Philautus microdiscus faces severe population decline primarily due to rapid deforestation and habitat conversion in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to localized habitat destruction from agricultural expansion and infrastructure development. Climate change poses an additional threat by altering the cool, humid microclimate conditions essential for this small tree frog's survival and reproduction.
Where does Kobo Bubble-nest Frog live?
Kobo Bubble-nest Frog occurs in India. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Kobo Bubble-nest Frog?
The main threats to Kobo Bubble-nest Frog are 2.3, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
