Overview

Craugastor andi is a species of rain frog in the family Craugastoridae which has not been seen since 1990. It is found in the Caribbean drainage of Costa Rica in the mountains and hills of the Cordillera Central and the far northeastern Cordillera de Talamanca, and in extreme northwestern Panama. Frank and Ramus (1995) give it the vernacular name Atlantic robber frog.

It is known locally in Spanish by the generic names, used for many species, of rana de hojarasca, ranita or sapito.

Craugastor andi faces severe pressure from the ongoing spread of chytrid fungus, a pathogen responsible for mass amphibian declines across its Central American range. Habitat loss from agricultural conversion and logging further reduces the moist forest floor conditions this direct-developing species requires for egg-laying and juvenile survival. Its naturally restricted distribution leaves remaining populations especially vulnerable to localized extinction events from disease outbreaks or habitat disturbance.

Threat summary

Habitat

This species inhabits pristine montane cloud forests between 1,800 and 2,200 meters elevation in Honduras' Cordillera Nombre de Dios. It requires areas with persistent fog cover, dense canopy, and abundant leaf litter where it can find the constant moisture and stable microclimates essential for its survival and reproduction.

Frequently asked questions

Why is Atlantic Robber Frog classified as Critically Endangered?
Atlantic Robber 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. Craugastor andi faces severe pressure from the ongoing spread of chytrid fungus, a pathogen responsible for mass amphibian declines across its Central American range. Habitat loss from agricultural conversion and logging further reduces the moist forest floor conditions this direct-developing species requires for egg-laying and juvenile survival. Its naturally restricted distribution leaves remaining populations especially vulnerable to localized extinction events from disease outbreaks or habitat disturbance.
Where does Atlantic Robber Frog live?
Atlantic Robber Frog occurs in Costa Rica, and Panama. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Atlantic Robber Frog?
The main threats to Atlantic Robber Frog are 11.1, and 8.1. The full IUCN-classified threat record for this species is detailed on the species page.
