Greater Pilalo Robber Frog

Pristimantis thymalopsoides

Declining

Overview

Pristimantis thymalopsoides is a species of frog in the family Strabomantidae.

Pristimantis thymalopsoides faces severe threats from rapid deforestation and agricultural expansion within its extremely limited range in the Cordillera Oriental of Peru. The species' restriction to high-elevation cloud forests makes it particularly vulnerable to climate change impacts, as warming temperatures force suitable habitat upslope with nowhere left to retreat. Mining activities and infrastructure development in the region pose additional pressures on the remaining forest fragments where this frog persists.

Threat summary

Habitat

This species inhabits montane cloud forests at elevations between 2,800-3,200 meters in the Cordillera Oriental of Peru. It requires the humid, moss-covered environments typical of Andean cloud forest ecosystems, where it likely breeds in terrestrial microhabitats among leaf litter and vegetation.
