Pristimantis

Describimos una nueva especie de Pristimantis conocida del bosque nublado de las estribaciones orientales de los Andes centrales de Ecuador, pristimantis. We describe a new pristimantis of Pristimantis, known from cloud forests of the eastern slopes of central Ecuadorian Andes.

Asignamos a Pristimantis almendariz sp. Pristimantis Hypodictyon ; serie de especies ridens; Pristimantis almendariz sp. This species, Pristimantis almendariz sp. The new species differs from other species of the ridens series by its distinctive dorsal spots, absence of tympanic membrane, presence of enlarged conical tubercles on the eyelid, prominent inter-orbital tubercle, and silver iris with black reticulations.

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

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.
