Rio Calima Robber Frog

Pristimantis diaphonus

Unknown

Overview

Pristimantis diaphonus is a species of frog in the family Strabomantidae. It is endemic to Colombia. Its natural habitats are tropical moist montane forests and rivers. It is threatened by habitat loss.

Pristimantis diaphonus faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted montane range. The species' extremely limited distribution makes it particularly vulnerable to localized environmental changes, with deforestation for cattle ranching and crop cultivation fragmenting its cloud forest habitat. Climate change poses an additional threat by altering the moisture regimes essential for this amphibian's survival in high-altitude ecosystems.

Threat summary

Habitat

This species inhabits montane cloud forests and humid highland areas, typically found in leaf litter and low vegetation of primary and secondary forests. It occurs at elevations between 2,000-3,000 meters in the Andean slopes, requiring consistent moisture levels and stable microclimatic conditions.
