Stefania Romagnoli
''Stefania'' is a genus of frogs in the family Hemiphractidae.

Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the ..., and adjacent far northern Brazil. Most are restricted to the tepui highlands, but '' S. evansi'' also occurs in lowlands. On most mountains there are only 1–2 species from this genus, but five are known from Mount Ayanganna and the neighbouring Mount Wokomung has six species. They are usually found near streams at low levels on branches/leaves or on the ground among vegetation/rocks. They are famous for their breeding strategy where the development from eggs to froglets is completed on the back of the female (the eggs hatch to froglets; there is no free-swimming tadpole stag ...

Stefania Evansi
''Stefania evansi'' is a species of frog in the family Hemiphractidae. ''Stefania evansi'' is, along with other closely related frogs, known for its unusual reproductive mode where females carry the eggs and juveniles on their back. It is sometimes known under common names Groete Creek carrying frog, Groete Creek treefrog, or Evans' stefania (the "treefrog" designation can be misleading as ''Stefania'' are no longer included in the family Hylidae). These names refer to its type locality, Groete Creek in the region Essequibo Islands-West Demerara, Guyana, where the holotype was collected by one Dr. R. Evans. Distribution and habitat ''Stefania evansi'' is endemic to Guyana and distributed in forested lowlands of west-central Guyana at altitudes below . Frogs collected at higher altitudes probably represent ''Stefania scalae'', a species that was for a while considered to be synonymous A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another wor ...

The snout is short and rounded or nearly truncate. The tympanum is distinct, round, and relatively large. The canthus rostralis is distinct. The fingers and toes have terminal discs and the toes have basal webbing. Skin on the dorsum is weakly granular. Ground color is greenish brown to brown.
