Pleurodema cinereum is a species of frog in the family Leptodactylidae. It is found in the Andes in northwestern Argentina, Bolivia, and southeastern Peru. Its common name is Juliaca four-eyed frog, after its type locality, Juliaca. Pleurodema borellii is possibly a junior synonym of this species.
Its natural habitats are open montane puna grasslands and semi-deciduous forests. Scientists have observed the frog between 600 and 4,200 m (2,000 and 13,800 ft) above sea level. Scientists have reported the frog in protected parks, many in Bolivia and two in Argentina: Los Andes Provincial Reserve and Laguna Pozuelos National Park.
Reproduction takes place in small permanent and temporary pools where pairs build floating foam nests. It is a common species facing no major threats. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Juliaca four-eyed frog is recorded against all the amphibians logged in Cochabamba (31 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
