As darkness blanketed the mountains of central Peru, a “long”-fingered creature took up its perch on a tree branch. Its “large” red eyes scanned the surrounding forest, but it wasn’t the only one looking around.
Visiting scientists noticed the “robust” animal — and discovered a new species.
A team of researchers hiked into Yanachaga-Chemillén National Park in 2010 for a roughly week-long wildlife survey. The park, situated in the Andes Mountains, was already known to have a “remarkable diversity of amphibians” so the group figured it would find something interesting, according to a study published Oct. 30 in the peer-reviewed journal PeerJ .
Sure enough, researchers found 10 unfamiliar-looking frogs during their nighttime searches, the study said. Intrigued, they took a closer look at the animals, analyzed their DNA and eventually realized they’d discovered a new species: Phrynopus manuelriosi, or Manuel Ríos’ Andes frog.
Manuel Ríos’ Andes frogs have “moderately robust” bodies reaching just over an inch in length, the study said. Their “flat” heads have “large” red eyes and a “bluntly rounded” snout. Their “slender” arms have “long” fingers, and their toes are “rounded.”
Photos show the color variation of the new species. The frogs vary from “pale brown” to “yellowish-brown or grayish-brown” with various “dark brown markings,” researchers said. Their bellies are paler and more yellow. Their sides and legs have bright red patches.
Manuel Ríos’ Andes frogs were found in an “elfin forest” at an elevation of about 10,760 feet, the study said. The frogs were on the ground or “perched on leaves and branches.”
Much about the new species’ lifestyle and behavior remains unknown.
Researchers said they named the new species after Manuel Ríos, “a Peruvian forest engineer and professor … who has dedicated his life to preserving the natural heritage of his country.”
So far, Manuel Ríos’ Andes frogs have only been found at one national park site in Oxapampa Province of central Peru, the study said. Although the new species lives within a legally protected area, researchers saw evidence of nearby habitat destruction and believe the frog’s survival “is not guaranteed if the borders of the protected area are not well protected.”
The new species was identified by its DNA, coloring, finger and toe shape, body proportions, skin texture and other subtle physical features.
The research team included Pablo Venegas, Luis Alberto García Ayachi, Lesly Lujan, Vilma Duran and Ana Motta.
The team also discovered a second new species of Andes frog with unique black markings.
