Describimos una nueva especie de Pristimantis conocida del bosque nublado de las estribaciones orientales de los Andes centrales de Ecuador. We describe a new species of Pristimantis, known from cloud forests of the eastern slopes of central Ecuadorian Andes. The new species is characterized by having distinctive white spots on black venter, green dorsum, conical tubercles on eyelid, interorbital tubercle, and row of ulnar and tarsal tubercles. Efforts to conserve this species are focused on two protected areas within the Llanganates-Sangay corridor, a hotspot that protects endemic and unknown populations of frogs. Las localidades, sus coordenadas y elevaciones fueron determinadas en base a las notas de campo de los colectores tomadas con un GPS.

However, the environmental and evolutionary factors that drive body size patterns at the interspecific level remain unclear. We found that the models that best explained body size in males, females, and SSD contained environmental variations in temperature, precipitation, and elevation as predictors. In turn, body size has evolved toward an optimum, with a decelerating rate of evolution differentiated between the large Pristimantis clades. Maximilian T. Body size is perhaps the most visible trait for most organisms.

According to the team, the new species — named Pristimantis mutabilis mutable rainfrog — changes skin texture in minutes, appearing to mimic the texture it sits on. Skin texture variation in one individual Pristimantis mutabilis ; note how skin texture shifts from highly tubercular to almost smooth; also note the relative size of the tubercles on the eyelid, lower lip, dorsum and limbs. Image credit: Zoological Journal of the Linnean Society. Pristimantis mutabilis , described in the Zoological Journal of the Linnean Society , is believed to be the first amphibian known to have this shape-shifting capability. It belongs to a large genus of approximately frog species found in the southern Caribbean and in Central and South America from Honduras to northern Argentina and southern Brazil. The scientists believe the ability to change skin texture to reflect its surroundings may enable Pristimantis mutabilis to help camouflage itself from birds and other predators.

We describe a new species of rain frog of the genus Pristimantis from the city of Loja, Southern Ecuador, based on an integrative taxonomy approach, combining molecular, morphological and bioacoustics data. Pristimantis lojanus sp. The new species can be easily distinguished from its closest congeners and morphologically similar species that also have acuminate snout with a fleshy keel by its characteristic advertisement call and morphological features dorsum finely tuberculate with scattered larger tubercles, flanks without longitudinal lateral folds, no markings in axilla, groin or on concealed limb surfaces, and bronze iris.
