Oreophrynella weiassipuensis is a species of toads in the family Bufonidae. It is only known from Wei-Assipu-tepui, a tepui on the border between Brazil and Guyana. [3] [4] The holotype was collected in 2000 by a speleological expedition to Wei-Assipu-tepui. [2] No other specimens are known. [4] It is possible that it is present in other localities, but most species of Oreophrynella are endemic to a single mountain. [2]

Description

The holotype, an adult male, measures 21 mm (0.83 in) in snout–vent length. Its characteristics are well developed post-orbital crests, well-developed webbing in hands and feet, dorsal skin that is minutely granular with scattered large tubercles particularly on the upper eyelids and flanks, and reddish brown dorsal and ventral coloration. The tympanum is absent. [2]

Habitat and conservation

The only known individual was found on moss in a wet forest at the bottom of a large chasm at 2,280 m (7,480 ft) above sea level. [2] There are no known threats to this species. The Brazilian part of the mountain is within the Monte Roraima National Park. [1]

<i>Oreophrynella</i> Genus of amphibians

Oreophrynella, commonly known as bush toads, is a genus of true toads native to the tepuis of southern Venezuela and adjacent Guyana. The distribution of some species is restricted to a couple of tepuis or even a single tepui, as in the case of Oreophrynella weiassipuensis, which occurs on Wei-Assipu-tepui.

<i>Anomaloglossus breweri</i> Species of amphibian

Anomaloglossus breweri is a species of frogs in the family Aromobatidae. It is only known from its type locality, Aprada-tepui in the Bolívar state of southeastern Venezuela. This species was discovered by scientists exploring the inaccessible and remote region of Aprada-tepui. It is a fast-moving frog that lives along creeks and in quiet pools along small streams along the slopes near the cave. The frog is named for Charles Brewer-Carías who collected the type series.

Amazophrynella minuta is a species of toad in the family Bufonidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. However, because of the poor description of new Amazophrynella species, it is not clear which old records refer to this species and which records refer to the new species.

<i>Oreophrynella macconnelli</i> Species of amphibian

Oreophrynella macconnelli is a species of toad in the family Bufonidae. It is found in Guyana, Venezuela, and possibly Brazil. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Incapable of leaping and able to crawl slowly, it can evade predators such as snakes by falling through the tree canopy to safety, its small size protecting it from injury.

<i>Oreophrynella nigra</i> Species of amphibian

Oreophrynella nigra, or pebble toad, is a species of toad in the family Bufonidae. It is endemic to the Guiana Highlands in Bolívar State, Venezuela, and known from two tepuis, Kukenan-tepui and Yuruani-tepui, both belonging to the Eastern Tepuis.

It has been recorded at elevations of 2,300–2,800 m (7,500–9,200 ft) above sea level.

<span class="mw-page-title-main">Wei-Assipu-tepui</span> Minor tepui in South America

Wei-Assipu-tepui, also known as Little Roraima or Roraimita, is a minor tepui of the Eastern Tepuis chain. It lies just off the northeastern flank of Roraima-tepui in the country of Brazil, directly on the border with neighboring Guyana in the disputed Essequibo territory, and very close to the tripoint of all three countries. The mountain is known for its extensive cave systems, with one extending for over a kilometre.

Maringma-tepui, also written Mount Maringma and historically known as Mount Marima, is a small tepui of the Pacaraima Mountains in Cuyuni-Mazaruni, Guyana. It is known as Malaima-tepui in the local Akawaio language. Most published sources place it just inside Guyanese territory, very close to the border with Brazil, and around 17 kilometres (11 mi) east of Roraima-tepui. However, the mountain remains the subject of considerable toponymic confusion and its name has been applied to at least one other nearby peak.

<i>Pristimantis jamescameroni</i> Small frog from Venezuela named after James Cameron

Pristimantis jamescameroni is a species of frog belonging to the family Strabomantidae. It is an orange-brown coloured small frog reported so far only from the Aprada-tepui, a table-top mountain in Bolívar state, Venezuela. It was discovered in June 2012 and formally described in October 2013 by Belgian biologist Philippe J. R. Kok at the Royal Belgian Institute of Natural Sciences and Vrije Universiteit Brussel. The species was named after the Hollywood filmmaker James Cameron, in recognition of his efforts in environmental awareness, and in addition to his public promotion of veganism as a way of animal conservation. Due to its restricted occurrence, the species could be classified as "endangered" according to the criteria of the IUCN Red List of Threatened Species.
