This species occurs in scattered lowland and premontane humid forest sites on the Atlantic slope from central Costa Rica (at elevations of 600-750m asl) to central Panama and in the Pacific lowlands and western slopes of the Western Cordillera in Colombia (100-1,000m), south to northwestern Ecuador (550-920m). In Colombia, it also occurs around northern edge of Cordillera Occidental and the Cordillera Central, and in the Magdalena Valley on the eastern slopes of the Cordillera Central and the western slopes of the Cordillera Oriental, reaching 1,600m in the Magdalena Valley.
Habitat and Ecology
It inhabits lower montane and lowland rainforest, where adults have been found in association with riparian vegetation and rocky streams, in which the tadpoles develop. Its adaptability to disturbed habitats is not known.
It is common in Colombia and Panama, but scarcer in Costa Rica and Ecuador.
The major threats are likely to be deforestation for agricultural development, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It has been recorded from three protected areas in Panama (including Parque Nacional Chagres), and from Parque Nacional Braulio Carrillo (Costa Rica). It occurs in several protected areas in Colombia, and in Ecuador, its geographic range overlaps with Reserva Ecológica Cotacachi-Cayapas.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich, et al., 2005).
