Gastrotheca albolineata (common name: white-lined treefrog) is a frog species in family Hemiphractidae. It is endemic to southeastern Brazil and known from São Paulo, Rio de Janeiro, and Espírito Santo states at elevations of 600–1,400 m (2,000–4,600 ft) asl.
Gastrotheca albolineata is a canopy dweller in primary and older secondary rainforests. It requires big trees as its habitat. Females carry the eggs on their backs, and eggs develop directly to froglets. Scientists have reported the frog in protected areas.
It is a common species but difficult to observe. It is not considered threatened by the International Union for Conservation of Nature (IUCN), but deforestation and agricultural encroachment are localized threats. Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-Lined Treefrog is recorded against all the amphibians logged in Serra dos Órgãos National Park (7 verified sightings from 2019 to 2026), 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.
