Stefania Fernandez
''Stefania'' is a genus of frogs in the family Hemiphractidae. They are native to the highlands of the Guiana Shield in southern Venezuela, Guyana, 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 A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found i ... stage). The c ...

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 ...

Stefania Coxi
''Stefania coxi'' is a species of frog in the family Hemiphractidae. It is endemic to Guyana and has been found on Mount Ayanganna and Mount Wokomung. Its natural habitat is subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial f ...s at higher elevations. References * MacCulloch, R.D. and A. Lathrop. 2002.

Stefania Tamacuarina
''Stefania tamacuarina'' is a species of frog in the family Hemiphractidae. It is found in the Sierra Tapirapecó in the Amazonas state of Venezuela as well as in the adjacent Amazonas state of Brazil (where the range is known as Serra do Tapirapecó). The specific name ''tamacuarina'' refers to the type locality, a spur ridge north of Pico Tamacuari. Description The type series consists of two sub-adult females measuring in snout–vent length; the maximum size could therefore be considerable higher. The head is slightly wider than it is long. 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. There are bold, darker brown patterns, including a large, rectangular brown blotch from between the eyes backwards to the level of arm insert ...
