Stefania roraimae (common names: Roraima treefrog, Roraima stefania) 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. [3] [4] [5] It presumably occurs in the adjacent Venezuela and Brazil too. [3]

Description

Male Stefania roraimae grow to snout–vent length of 36–46 mm (1.4–1.8 in) and females to 36–68 mm (1.4–2.7 in). The smallest recorded independent juveniles are 19 mm (0.75 in) in snout–vent length. Reproduction is not known for this species, [6] but presumably the females carry eggs on their backs, with the juveniles developing fully there, [1] as known for many other species of Stefania . [7]

Habitat and conservation

Stefania roraimae are found in primary forests at altitudes of 1,234–1,550 m (4,049–5,085 ft). There are no known threats to this species in its relatively remote habitats. [1]

<i>Cryptobatrachus</i>

Cryptobatrachus is a genus of frogs under family Hemiphractidae. They are found in Colombia and Venezuela. They are commonly called backpack frogs, as the females have the habit of carrying their clutch on their backs until the young hatch; this behaviour also occurs in the related hemiphractid genera Hemiphractus and Stefania.

<i>Flectonotus</i>

Flectonotus is a genus of frogs of the family Hemiphractidae. They are found on the Andes of northeastern Colombia and adjacent Venezuela as well as in Trinidad and Tobago.

<i>Stefania</i>

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.

<i>Oreophrynella quelchii</i>

Oreophrynella quelchii, commonly known as the Roraima black frog or Roraima bush toad, is a species of toad in the family Bufonidae. This species is restricted to the transboundary summit of Mount Roraima in Venezuela, Guyana and Brazil, and to the nearby Wei-Assipu-tepui on the Brazil–Guyana border. It has been recorded at elevations of 2,300–2,800 m (7,500–9,200 ft) above sea level.

<i>Anomaloglossus beebei</i>

Anomaloglossus beebei is a species of frog in the family Aromobatidae. It is endemic to Guyana and only found on the Kaieteur Plateau, in the eastern edge of them Pacaraima Mountains. Recently, it has also been found on Mount Ayanganna.

<i>Adelphobates galactonotus</i>

Adelphobates galactonotus is a species of poison dart frog. It is endemic to the rainforest of the southern Amazon Basin in Brazil. Its natural habitats are tropical moist lowland forests. The eggs are laid on the ground, but the tadpoles are carried to temporary pools. Though it remains widespread and locally common, it is threatened by habitat loss and has already disappeared from some localities due to deforestation and flooding caused by dams. The species is relatively common in captivity and regularly bred, but the wild populations are still at risk from illegal collection.

<i>Stefania evansi</i> Species of frog

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.

Hemiphractidae

The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae, Cryptobatrachidae, and Hemiphractidae (Hemiphractus). An active question still exists as to which of these groupings is more accurate.
