Psychrophrynella is a genus of frogs in the family Strabomantidae[2] The genus is distributed on the Andes of southern Peru and Bolivia.[3] One of the four species assessed by the International Union for Conservation of Nature (IUCN) is 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]
