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.
"Cochranella" duidaeana, commonly known as the Duida Cochran frog, is a species of frog in the family Centrolenidae. It is endemic to Cerro Duida, Venezuela. The generic placement of this species within the subfamily Centroleninae is uncertain.
Hyloxalus breviquartus is a species of frog in the family Dendrobatidae. It is found in the northern part of Cordillera Occidental in Antioquia, Colombia, and in Carchi Province in northwestern Ecuador. Colombian distribution may be wider. Its natural habitats are montane forests next to streams and very humid premontane forests. It is threatened by habitat loss, although it occurs in the Las Orquídeas National Park, its type locality.
Anomaloglossus shrevei is a species of frog in the family Aromobatidae. It is endemic to Venezuela where it is only known from the Cerro Marahuaca and Cerro Duida, two adjacent tepuis. These frogs live near streams in tropical rainforest. It is not a common species but the population may be presently stable and is protected by Parque Nacional Duida-Marahuaca.
Minyobates steyermarki is a species of frog in the family Dendrobatidae endemic to Cerro Yapacana in southern Venezuela. It is also known by the common names of demonic poison frog, demonic poison-arrow frog, or Yapacana's little red frog. It is monotypic in the genus Minyobates.
The Monte Duida tree frog is a species of frog in the family Hylidae. It is endemic to Venezuela and only known from the Cerro Duida, its type locality in the Amazonas state of southern Venezuela. Its natural habitat is montane tepui vegetation, specifically forest and shrubs adjacent to rivers, streams, and peat bogs. No significant threats to this species occurring in the Duida-Marahuaca National Park are known.
Dischidodactylus colonnelloi is a species of frog in the family Craugastoridae. It is endemic to Venezuela and only know from its type locality, Cerro Marahuaca, in the Amazonas State. The holotype was collected by G. Colonnello, hence the specific name colonnelloi.
Dischidodactylus duidensis is a species of frog in the family Craugastoridae. It is endemic to Venezuela and only known from its type locality, Cerro Duida. It was formally described in 1968 by Juan A. Rivero, even though the type series was collected 40 years earlier by George Henry Hamilton Tate.
Eleutherodactylus portoricensis is a frog native to Puerto Rico that belongs to the family Eleutherodactylidae. Its vernacular English names are upland coqui, mountain coqui, and Puerto Rican robber frog. It is found in the Toro Negro State Forest and other similar mountainous regions.
Stefania breweri, also known as Brewer's carrying frog, is a species of frog in the family Hemiphractidae. It is endemic to Cerro Autana, Venezuela, and only known from a single specimen (holotype). It was named for Venezuelan explorer Charles Brewer-Carías.
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. 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.
Stefania ginesi is a species of frog in the family Hemiphractidae. It is endemic to the Chimantá Massif, Venezuela. Its natural habitats are humid rocky habitats on tepuis. While its range is restricted, it is a common species within its range. It can be found in crevices, caves, on open rock surfaces and adjacent peat bogs, in streams and rivers. Its range overlaps with the Canaima National Park.
Stefania marahuaquensis is a species of frog in the family Hemiphractidae. It is endemic to Venezuela and known from Cerro Duida and Cerro Marahuaca, both in Amazonas State. Its occurs on rocks along the forested margins of small streams at elevations of 340–1,200 m (1,120–3,940 ft) asl. The range is within the Duida–Marahuaca National Park, and no major threats to this species have been identified.
Stefania oculosa is a species of frog in the family Hemiphractidae. It is endemic to the Bolívar state of southern Venezuela and only known from Cerro Jaua, a tepui; it possibly occurs more widely. It was found on rocks in a fast-flowing cascading stream where it co-occurred with Stefania percristata. The known range is within the Jaua-Sarisariñama National Park, and the species is not facing known threats.
Stefania percristata is a species of frog in the family Hemiphractidae. It is endemic to Venezuela and only known from its type locality, Cerro Jaua in Bolívar State. It occurs along streams at the top of the tepui. It is a nocturnal species found on branches of vegetation 0.3–1 m above the ground.
Stefania riae is a species of frog in the family Hemiphractidae. This species is only known from Cerro Sarisariñama, a tepui in the Bolívar State, Venezuela.
Stefania roraimae is a species of frog in the family Hemiphractidae. It is endemic to Guyana. Its type locality is Mount Roraima; it is also known from Mount Ayanganna and Mount Wokomung. It presumably occurs in the adjacent Venezuela and Brazil too.
Stefania woodleyi is a species of frog in the family Hemiphractidae. It is endemic to the eastern part of the Pakaraima Mountains in Guyana, including Mount Wokomung and Mount Ayanganna.
Cerro Duida, also known as Cerro Yennamadi, is a very large tepui in Amazonas state, Venezuela. It has an uneven and heavily inclined plateau, rising from highs of around 1,300–1,400 metres (4,300–4,600 ft) in the north and east to a maximum of 2,358 metres (7,736 ft) on its southwestern rim. It has a summit area of 1,089 km2 (420 sq mi) and an estimated slope area of 715 km2 (276 sq mi). At its foot lies the small settlement of La Esmeralda, from which the mountain can be climbed.
Hyloxalus parcus is a species of frogs in the family Dendrobatidae. It is endemic to Ecuador where it is only known from its type locality in the Zamora-Santiago Provinceat elevation of 1,981 m (6,499 ft) asl.
