This species is known only from the type locality, near Quebrada Valverde, near Tapantí, Cartago Province, Atlantic versant, Costa Rica, at 1,555-1,650m asl (Savage 2002).
Habitat and Ecology
It lives in arboreal vegetation (mosses and liverworts) in lower montane rainforest. It does not occur in degraded habitats. It breeds by direct development and is not dependent upon water.
Only two specimens plus some egg clutches are known. It has not been recorded in recent surveys, however it occurs in arboreal vegetation and is difficult to find (Federico Bolaños pers. comm. 2007).
There are no major threats known. However, its small range renders it vulnerable to stochastic threatening processes.
The area where this species was collected is now within the Parque Nacional Tapantí. There is a need for additional survey work to determine and monitor the population status of this species.
Red List Status
