Uribe Robber Frog

Pristimantis molybrignus

Declining

Overview

Pristimantis molybrignus is a species of frog in the family Strabomantidae. It is endemic to Colombia. Its natural habitats are tropical moist montane forests, rivers, and heavily degraded former forest.

Pristimantis molybrignus faces severe threats from ongoing deforestation and habitat conversion in its restricted montane range. Mining activities and agricultural expansion have fragmented the remaining cloud forest patches where this species occurs. The frog's extremely limited distribution makes it particularly vulnerable to localized habitat destruction, with entire populations potentially eliminated by single development projects.

Threat summary

Habitat

This species inhabits montane cloud forests and humid upper montane forests, typically found in leaf litter and low vegetation in pristine forest environments. It occurs at elevations between 2,000-3,000 meters in the Andean slopes of Ecuador.
