This species occurs in south-western Ecuador (in El Oro, Azuay and Loja Provinces) and north-western Peru (in Ancash, Piura and Tumbes regions), west of the Andes, at 153-1,769m asl. The record from Ancash, Peru, is doubtful (E. Lehr pers. comm.). It is likely to occur a little more widely than current records suggest.
Habitat and Ecology
It lives in equatorial dry forest near streams and can be found in altered habitats. It lays its eggs in leaf-litter, and the males carry the larvae to running and standing water where they continue their development.
In southern Ecuador this is an abundant species.
This species is threatened by agrochemical pollution of waterways, and is also collected for medicinal use in Ecuador (although not currently in sufficient numbers to be a threat).
It is not known with certainty if it occurs in any protected areas. The impact on it of collection for medicinal use and commercial trade in wild specimens should be monitored.
This species and Epipedobates tricolor were recently separated by Schulte (1999). We follow Graham et al. (2004) in restricting the distribution of E. anthonyi to southern Ecuador and northern Peru.
