From the IUCN Red List Species Account:


Range Description

This recently described species is known only from the Volcán Miravalles and the Volcán Rincón de la Vieja in the Cordillera de Guanacaste, Costa Rica (Vaughn and Mendelson, 2007). These mountain ranges are geographically isolated from the ranges of other species of Crepidophryne (Vaughn and Mendelson, 2007). The range appears to remain poorly known, however it has not yet been located during surveys in adjacent mountain peaks (Gerado Chaves pers. comm.). It is found between around 1,900 to 2,000m asl.

Habitat and Ecology

It is restricted to cloudforest and wind-swept elfin forest (Vaughn and Mendelson, 2007). Animals are presumably associated with deep leaf litter, as are other members of this genus. It is possible that this species undergoes direct development, however this requires further investigations (Vaughn and Mendelson, 2007).


It is currently known only from three speciemens, and there is no information on the abundance of this species (Federico Bolaños and Gerardo Chaves pers. comm.).

Population Trend


Major Threats

The current known range of this species is fully within well-protected areas, and there are not considered to be any major threats ongoing or predicted.

Conservation Actions

It has been recorded from the Parque Nacional Volcán Rincón de la Vieja, Distrito Liberia, Canton Liberia; and from the protecetd watershed of Miravalles (Gerardo Chaves pers. comm.). Further surveys are needed to better define the full extent of this species range.

Red List Status

Data Deficient (DD)


Listed as Data Deficient, as the range and population dynamics of the species remain poorly known, and it is entirely possible that it is declining outside of the Volcán Miravalles and the Volcán Rincón de la Vieja.

Taxonomic Notes

Recently separated from Crepidophryne epiotica by Vaughn and Mendelson (2007).
