This species occurs primarily in the humid, lower montane zone of the Cordillera de Tilarán, Cordillera Central, and Cordillera de Talamanca of Costa Rica and the Pacific slope of western Panama, but marginally in humid areas of the premontane zone, from 1,120-2,340m asl (Savage, 2002).
Habitat and Ecology
It is a largely nocturnal tree frog of humid montane forest. It can be found in trees in pastures and similar open areas; it is commonly found in puddles on roads (Federico Bolaños pers. comm.). The species is an explosive small pond breeder; reproduction follows heavy rains, eggs are laid in small masses in the water.
In general, it is a very common species. In Panama, this species is presumed to have undergone some declines in the Reserva Forestal Fortuna. Although this species declined at one point at Monteverde and Cascajal, Costa Rica, populations have since recovered at Monteverde, and this species remains commonly encountered within Costa Rica.
Generally, it is threatened by habitat loss through the destruction of natural forests. While museum specimens of this species have been found to have the chytrid fungi, the current impact of this pathogen on the species is not known.
Although there are no specific conservation measures in place, the species has been recorded from a number of protected areas in Costa Rica and a single protected area in Panama.
This species was previously within the genus Hyla but has recently been moved to the new genus Isthmohyla (Faivovich, et al., 2005).
