Pristimantis

The description of the new species is based on the examination of eleven adult males and three adult females, pristimantis. Pristimantis new taxon can be readily distinguished from other congeneric species that inhabit the eastern Andes of Ecuador by the unique pristimantis of the following characters: small body adult males SVL Additionally, pristimantis, we provide information on the advertisement call and natural history of the new species.

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.

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. Katherine and Tim Krynak originally spotted the small, spiny frog, nearly the width of a marble, sitting on a moss-covered leaf about a yard off the ground on a misty July night in The scientists captured one specimen and tucked it into a cup with a lid before resuming their nightly search for wildlife.

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. Additionally, we describe the advertisement call of its sister species, P. Finally, we detail the current situation of the amphibian species present in the city of Loja and its surroundings.

Pristimantis is a very large genus of frogs distributed in the southern Caribbean islands Lesser Antilles and in Central and South America from Honduras to northern Argentina and southern Brazil. Placement of this genus has varied greatly. Pristimantis was long included in the massive genus Eleutherodactylus , and considered part of the family Leptodactylidae.
