Psychrophrynella is a genus of frogs in the Craugastoridae family.[2] Alternatively, it has been placed in the Strabomantidae family.[3] The genus is distributed on the Andes of southern Peru and Bolivia.[2] Four of the 21 species are assessed as "Critically Endangered".[4]

The name Psychrophrynella is a contraction of the Greek psychros meaning cold and phrynos meaning toad, with the Greek diminutive suffix ella. It refers to their relatively cold habitats.[1]

Description

Psychrophrynella are small frogs measuring between 14 and 33 mm (0.55 and 1.30 in) snout–vent length. They are characterized by narrow head, absence of differentiated tympanic membrane (except in Psychrophrynella boettgeri) and, in most species, absence of tympanic annulus. Dorsum is smooth, granular, or shagreen. Venter is finely granular, granular, or coarsely granular (but smooth in Psychrophrynella pinguis).[1]
