This species is present throughout much of Amazonian Peru, including northern Departamento Loreto to the Iquitos area, through to the southeastern areas adjacent to the rivers Tambopata and Manu (Departamento Madre de Dios). It is also known from the vicinity of the Jurua river, Amazonas, Brazil, and a recent record from close to Parque Nacional Madidi, Bolivia. Its elevation is from 200-280m asl.
Habitat and Ecology
Generally, it is present in the understorey vegetation of humid tropical forest. Breeding congregations assemble near pools, egg deposition site not known; larvae develop in the temporary ponds. It is not known if the species can occur in secondary or modified habitats.
This is an abundant species. Duellman and Trueb (1989) stated that based on the number of individuals observed in breeding congregations, H. koechlini would be among the most abundant anurans at Cusco Amazonico. Later, Duellman (1995) found Hyla koechlini to be the most abundant species of frog at Cusco Amazonico. It is also common in the Tambopata National Reserve (A. Angulo pers. obs.).
Present in a well conserved region with few threats.
This species is known to occur in Tambopata National Reserve, and given its known habitat and geographical distribution, it might occur in Allpahuayo Mishana Reserved Zone, Pacaya Samiria National Reserve, and Bahuaja Sonene National Park, Peru.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich, et al., 2005).
