Pristimantis

The description of the new species is based on the examination of eleven adult males and three adult females, pristimantis.

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. Adicionalmente, P.

New species are described every year, mainly from the Andes Lehr et al. The remarkable diversity of this terrestrial group may be associated with the success of their reproductive mode. Our knowledge of the diversity of this genus is thus still incomplete, and the rate of species discovery remains high throughout the Andes, including in eastern Peru, where several species have recently been described e. Here we describe a new species of Pristimantis found in the bromeliads of a cloud forest remnant in the Cordillera de Carabaya Fig. This specimen does not resemble any of the previously described species of Pristimantis. Furthermore, molecular data indicate that the sequence of a fragment of 16S rRNA does not match any known sequence of Pristimantis.

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
