Boana cinerascens

The Demerara Falls tree frog, Boana cinerascens, is a hylid of the Amazon region of South America, also found in Guyana, Suriname, French Guiana and Venezuela (Wikipedia, general species account). It is a species complex. Barrio-Amorós (2019) notes that the name hides several taxa, and that in Venezuela two of them are confused under it, one from rainforest and one from open areas. Its type locality is Ega, now Tefé, in Amazonas, Brazil (Barrio-Amorós 2019).

Its natural habitats are subtropical or tropical moist lowland forests, swamps, rivers, freshwater marshes, rural gardens and heavily degraded former forests (Wikipedia, general species account). Eggs are laid in clumps in streamside ponds in terra-firme forest, and a clutch contains 165 to 298 pigmented eggs (Lima et al. 2012; Telles et al. 2013). Tadpoles are found in streamside ponds and less often in streams, in most months of the year (Tadpoles of Central Amazonia).
