This species is known only from the town of Cobija (11° 00' 45''S; 68° 45' 27''W), at 250m asl, in Nicolas Suarez Province, Pando Department, extreme northern Bolivia (close to the border with Peru), and from Riberalta, in Beni Province, Bolivia. It is likely to have a much wider distribution in Bolivia and neighbouring Peru.
Habitat and Ecology
This is apparently not a forest species, and it has been found in open habitats with tall grass around small ponds and roadside ditches. It is probably well adapted to anthropogenic disturbance, and presumably breeds in ponds and ditches.
It is common at Cobija, although it is hard to find in certain seasons.
Since it is an adaptable species it is not likely to be facing any particular threats at present.
It has not yet been recorded from any protected areas.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich et al. 2005).
