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]
Species of the genus 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]
The following species are recognised in the genus Psychrophrynella: [3] [2]
The Brachycephalidae are a family of frogs confined to eastern and southern Brazil and northern Argentina. The family is composed of two externally quite different genera: the tiny, often colourful and plump saddleback toads (Brachycephalus) from Brazil, and the larger, slimmer and more drab genus Ischnocnema from both Brazil and Argentina. The family is mainly defined by molecular characteristics, and are linked by few anatomical features. It was erected from two genera of the previously large family Eleutherodactylidae, which is now split into four families.
The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under the common name rain frogs. Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species.
Barycholos, common name Chimbo frogs, is a genus of small frogs in the family Strabomantidae found in south-eastern Brazil and tropical lowland Ecuador. The name Barycholos, from the Greek βαρύχολος ("savage"), is in honor of herpetologist Jay M. Savage.
Mount Duida frogs (Dischidodactylus) form a genus of brachycephaloid frogs endemic to the tepuis of southern Venezuela. The scientific name is derived from the Greek dischidos, meaning divided, and dactylos, meaning finger or toe, in reference to the divided ungual flap.
Euparkerella, sometimes known as Guanabara frogs, is a genus of frogs in the family Strabomantidae. They are endemic to the Atlantic coastal forests in the south-eastern Brazilian states of Espírito Santo and Rio de Janeiro. The name Euparkerella honours H. W. Parker, a herpetologist who named the type species, with the Greek prefix eu meaning true and suffix ella, a diminutive form.
Holoaden, the highland frogs, is a small genus of frogs in the family Strabomantidae. The species are endemic to south-eastern Brazil.
Phrynopus is a genus of frogs of the family Strabomantidae. Their common name is Andes frogs. They are endemic to Peru and inhabit the upper humid montane forest and supra-treeline grassland in the Cordillera Oriental, with one record from the Peruvian Cordillera Occidental.
Oreobates saxatilis, also known as Tarapoto big-headed frog, is a species of frog in the family Strabomantidae. It is endemic to Peru and known from near its type locality near Tarapoto as well as from the Río Tambo District in the Satipo Province, Panguana in the Puerto Inca Province, and Río Kimbiri in the La Convención Province.
Niceforonia nana is a species of frog in the family Strabomantidae. It is endemic to the Cordillera Oriental, Colombia, and found at 3,000–3,850 m (9,840–12,630 ft) asl.
The Strabomantidae, sometimes called cloud forest landfrogs, are a family of frogs native to South America. These frogs lack a free-living larval stage and hatch directly into miniature "froglets". This family includes Pristimantis, the most speciose genus of any vertebrate. Based on molecular dating, the Holoadeninae in particular appears to have originated in the Eocene. The Oligocene-Miocene transition was also found to be important to their biogeographical history. However, the lack of Holoadeninae fossils and limited nucleotide data ambiguates the results, by the authors' admission.
Bryophryne is a genus of frogs in the family Strabomantidae. These frogs are endemic to south-eastern Peru in the Cusco Region, with an undescribed species from the Puno Region. Their range is separated from that of Phrynopus by the Apurímac River valley.
Craugastoridae, commonly known as fleshbelly frogs, is a family of New World direct-developing frogs. As delineated here, following the Amphibian Species of the World, it contains 129 species. They are found from the southern United States southwards to Central and South America.
Haddadus is a genus of frogs in the family Craugastoridae. The genus has three species that are endemic to the Atlantic Forest of east and southeast Brazil. The genus is named for Célio F. B. Haddad, Brazilian herpetologist.
Diasporus is a genus of frogs in the family Eleutherodactylidae. The genus was first described in 2008. They are found in Central and northern South America. They are sometimes referred to as dink frogs, in reference to the "tink" sound that males make during the mating season.
Lynchius is a genus of frogs in the family Strabomantidae. The name honours herpetologist John D. Lynch. The distribution of Lynchius is restricted to the Cordillera Oriental in southern Ecuador and Cordillera de Huancabamba in northern Peru.
Niceforonia is a genus of frogs in the family Strabomantidae found in northern South America. The name refers to Nicéforo María, Colombian herpetologist.
Noblella is a genus of frogs in the family Strabomantidae. They are found on the eastern slopes of the Andes and in the Amazon Basin in Colombia, Ecuador, Peru, Bolivia, and western Brazil. The name refers to Gladwyn K. Noble, who described the first species.
Psychrophrynella usurpator is a species of frogs in the family Strabomantidae. It is endemic to Peru and known from near Abra Acjanacu, a mountain pass in the Cordillera de Paucartambo, the easternmost Andean range towards the Amazonian lowlands, and from the high elevation grasslands of the Manu National Park. It is named usurpator, because these frogs were previously misidentified as Noblella peruviana — in a sense, they had "usurped" the name of another frog species.
Psychrophrynella chirihampatu is a species of frogs in the family Strabomantidae. It is endemic to Peru and known only from its type locality, the Japumato Valley in the Peruvian Andes of the Cusco. The common name Japumayo Andes frog has been coined for this species.
Qosqophryne is a genus of strabomantid frogs. These frogs are endemic to south-eastern Peru in the Cusco Region at 3270 to 3800 meters above sea level. A phylogenetic analysis found Qosqophryne as sister to the genus Microkayla and that this clade was more closely related to Noblella and Psychrophrynella than to other species in Bryophryne.
