This species occurs in eastern Venezuela, Guyana, Suriname, and northern and central Brazil extending into Rondonia, Brazil (Araújo et al. 2007). Disjunctive records from Parque Nacional da Serra do Divisor and Reserva Extrativista do Alto Juruá in western Acre State in western Brazil might refer to another species. Despite its wide distribution, it is known from only a few records, possibly due to lack of herpetological work within its range. Venezuelan specimens were previously reported as Pipa aspera (La Marca 1992). It is a lowland species, occurring up to 860 m asl.
Habitat and Ecology
It is an aquatic species living in permanent and temporary waterbodies in tropical rainforest, including ponds, puddles and roadside ditches. These animals can cross land when their ponds dry out. Direct development takes place on the dorsum of the adult in water. It is apparently adaptable to human disturbance (although a population in eastern Venezuela disappeared after a road was asphalted).
It is a common species and the population appears to be stable.
It is probably not seriously threatened, but local subpopulations are likely to be impacted by logging and fire.
