Boana riojana is a species of frog in the family Hylidae. It is found in the eastern Andes and the Andean foothills between La Rioja Province in Argentina and northern Bolivia, and possibly further into adjacent Peru. Common name Carrizo's tree frog has been used when referring to the formerly recognized Boana varelae (Carrizo, 1992).
Boana riojana occurs at elevations of 1,650–3,400 m (5,410–11,150 ft) in the north and 500–1,640 m (1,640–5,380 ft) in the south. Ecological requirements of this species are largely unknown. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rioja Tree Frog is recorded against all the amphibians logged in Cochabamba (27 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.
