Ololygon albicans ( Syn. : Scinax albicans ) is a neotropical Froschlurch from the subfamily of the scinax (Scinaxinae) within the family of tree frogs . This species was previously included in the genus Scinax and assigned to the Scinax catharinae clade. From 2016 this clade was listed as a separate genus under the name Ololygon .

distribution

This species is endemic to the Serra do Mar in the Brazilian state of Rio de Janeiro and comes to an altitude of 1200 m above sea level. NN before.

description

Compared to other representatives, this species belongs to the medium-sized knee-toe tree frogs. It is characterized by its triangular shape of the head (from a dorsal point of view) and its short, flattened snout. The back is brightly colored and has no defined markings. The thigh and groin region have black spots that form transverse stripes. Its tadpoles also have a rounded snout. In addition, like all members of the genus Ololygon group, it has a characteristic dorsal coloration (for an illustration see Salles et al. (2009: 845)).

Habitat and Ecology

Scinax albicans is found on vegetation near small streams, which it also uses for reproduction. It only occurs in primary forests and old secondary forests and has not yet been detected outside of forest areas.

Danger

The IUCN lists Scinax albicans as " Least Concern ". This is due to its wide distribution and the fact that the total population is estimated to be sufficiently large. The processors consider it unlikely that stocks of the species can decline quickly enough to justify a higher endangerment level. However, the stocks show declining development trends and the species is only found in a few protected areas. Habitat loss through deforestation, fire and agricultural use are the main threats to the species.
