This species is known only from the type locality on the north-facing premontane slope of the Cordillera de Talamanca, near Moravia de Chirripó, in Cartago Province in eastern Costa Rica, at 1,100-1,200m asl. Its distribution is not well understood, and it might occur more widely.
Habitat and Ecology
It lives in premontane rainforest, probably in moss mats, and presumably breeds by direct development.
There is no information on the population status of this species, which is known from one specimen only, and is likely to be rare.
The major threat is loss of habitat due to increased urbanization, and expanding smallholder farming and cattle ranching activities.
It is not found in any protected areas, but does occur in the Reserva Indígena Chirripó.
