Adelophryne patamona is a species of frog in the family Eleutherodactylidae. It is endemic to the Pacaraima Mountains of southwestern Guyana, [3] [4] although it is likely to also occur in the adjacent Roraima state of Brazil. [1] [3] It is most closely related to A. gutturosa . [5]

Description

Adult males measure 17–18 mm (0.67–0.71 in) (based on just two individuals) and adult females 21–23 mm (0.83–0.91 in) in snout–vent length. It is the largest species of its genus. The snout is rounded. The tympanum is small and covered by a fold posterodorsally. The skin of the dorsum, venter, and limbs is smooth but has scattered small tubercles. The flanks and rear of the thighs are areolate. The front toes are flattened, unwebbed, and have small pointed discs at their tips. The back toes are also flattened, unwebbed, and have small narrow discs at their tips. Colouration is variable; the colour of the dorsum, flanks, and dorsal surfaces of limbs is medium brown, and there are black markings. Some specimens are darker and have more pale blue spots and more conspicuous tubercles on dorsum. [2]

The male advertisement call is a group of three soft, unpulsed, whistle-like notes. The first two are short and third one is long, all produced in rapid succession. [2]

Habitat and conservation

Adelophryne patamona is known from medium-cover forests at elevations of 678–1,414 m (2,224–4,639 ft) above sea level (the highest of all Adelophryne species [2] ). Specimens have been found amidst leaf litter, among rootlets near the base of trees, and in ground holes covered by leaves. Males call in the afternoon and night, mostly from concealed sites. [1] [2]

This species is common in its native range. Human population is sparse in the area. However, gold mining the area could be a threat to its habitat. [1]

Adelophryne is a genus of frogs in the family Eleutherodactylidae. They are native to northern South America east of the Andes, known roughly from the area corresponding to the Guiana Shield, as well as to the coastal area of Bahia, Brazil. Whether the genus is truly distinct from Phyzelaphryne remains uncertain. Common name shield frogs has been proposed for this genus, although the stem flea frog is used for some species.

It is possible that it is present in other localities, but most species of Oreophrynella are endemic to a single mountain.

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.
