Oreobates is a genus of frogs in the family Strabomantidae. [1] Most species were formerly in the genus Ischnocnema , but were moved to this revalidated genus following a 2006 revision. [2] Its sister taxon is Lynchius . [1]

These frogs are found in the lower slopes of the Andes into the upper Amazon Basin from Colombia south to northern Argentina and east into western Brazil. [1]

Description

Frogs in the genus Oreobates are small to medium-sized with males measuring 20–44 mm (0.79–1.73 in) and females 25–63 mm (0.98–2.48 in) in snout–vent length. They are generally brownish in colour. Body is robust with a short snout. The toes lack discs and fingers have reduced or absent discs; there is no webbing. [3]

<i>Centrolene</i> Genus of amphibians

Centrolene is a genus of glass frogs in the family Centrolenidae. The adult males are characterized by having a humeral spine, as most members of this family. The delimitation of this genus versus Cochranella is not fully resolved, and some species formerly in Centrolenella — which is nowadays synonymized with Centrolene — are now in Hyalinobatrachium.

The area was mined during the Cenepa War in 1995, and has consequently seen little human activity, although this may change through a proposed road.

Oreobates amarakaeri, also known as Amarakaeri's big-headed frog is a species of frog in the family Strabomantidae, which is endemic to a small region of south-eastern Peru, in the Manú District, and parts of the Puno Region. The frog was first discovered near the Rio Nusinuscato and Rio Mabe rivers in the Andean foothills of the Amarakaeri Communal Reserve, which are tributaries of the Rio Araza. Since then the species has also been found at the Manú Learning Centre and near Bahuaja Sonene National Park, but weren't fully confirmed to be there until 2019 when four specimens were collected at those localities. At the Manú Learning Centre the frog is known to occur mainly in low disturbance and primary forest habitat, but can also be found near streams in more disturbed areas.
