Yunganastes

Yunganastes is a small genus of craugastorid frogs found in southern Peru and central to northern Bolivia. They were formerly included in Eleutherodactylus as the "Eleutherodactylus fraudator group", subsequently moved to Pristimantis, before becoming recognized as a separate subgenus, and finally, a genus. Its sister taxon is Pristimantis.[2] Yunganastes are endemic to the cloud forests and humid montane forests of the Cordillera Oriental of the Andes in Bolivia and southern Peru.[1]

Etymology

The generic name Yunganastes is derived from yunga, the humid forests of the Andean valleys, and the Greek nastes for "dweller". This refers to the typical habitat of frogs in this genus.[1]

Description

Yunganastes are robust-bodied and moderate to medium-sized frogs. Males can reach 52 mm (2.0 in) and females 63 mm (2.5 in) in snout–vent length. The limbs are moderately long. The head is as wide or wider than the body; the snout is short. The tympanum is visible, and the supra-tympanic fold is well-developed. The toes have rudimentary or no webbing. Males have a large vocal sac. The male advertisement call is single melodic whistle with frequency modulation and relatively low dominant frequency of about 1200–1500 Hz.[1]

Species

There are five species:[2][3]
