From the IUCN Red List Species Account:

Range Description

This species is known only from the type locality, near El Empalme (along the Pan-American Highway, south of Cartago) at the northern end of the Cordillera de Talamanca, Costa Rica, at about 2,286m asl (Savage 2002).

Habitat and Ecology

It inhabits lower montane rainforest, and possibly lives below the ground. It breeds by direct development and is not dependent upon water.

Population

There is no information on current population status; no individuals have been collected since 1952 (Savage 2002; Federico Bolaños pers. comm. 2007), and it is possible that it is now extinct.

Population Trend

decreasing

Major Threats

The major threat is likely to be loss of habitat due to increased urbanization, and expanding smallholder farming and cattle ranching activities.

Conservation Actions

It is not known from any protected area, and habitat protection is urgently needed. Further survey work is also needed to determine the current population status of this species and whether or not it survives in the wild.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in the northern Cordillera de Talamanca, Costa Rica.
