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]

Contents

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

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 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.

<span class="mw-page-title-main">Eleutherodactylidae</span> Family of amphibians

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.

<i>Barycholos</i> Genus of amphibians

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), is a genus of craugastorid 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.

<i>Euparkerella</i> Genus of amphibians

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.

<i>Noblella</i> Genus of amphibians

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.

<i>Psychrophrynella usurpator</i> Species of amphibian

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.

<i>Psychrophrynella chirihampatu</i> Species of amphibian

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.
