Overview

Phyllonastes coloma, commonly called Coloma's noble rainfrog, is a species of frog in the family Craugastoridae. It is endemic to Ecuador, and found in the Cordillera Occidental range.

Phyllonastes coloma faces severe threats from rapid deforestation and habitat conversion in its restricted montane cloud forest range. Mining activities and agricultural expansion have fragmented the remaining forest patches, while climate change is causing upward shifts in cloud formation that may eliminate suitable microhabitats. The species' extremely limited distribution makes it particularly vulnerable to any local environmental changes or disturbances.

Threat summary

Habitat

This species inhabits montane cloud forests at elevations between 1,800-2,400 meters in the Andes. It requires the specific microclimate conditions of persistent cloud cover and high humidity found in these threatened ecosystems.
