Abstract
A new species of Craugastoridae frog encountered from 1000–1700 m in elevation in the premontane forests of the Peruvian central Andes is described. The new species is similar in appearance to many other species of Pristimantis, but is easily distinguishable from these species by having bright red coloration on the groin, posterior surface of thighs, and shanks. The new species is only known for two localities 27 km apart in the Huánuco Region.

Etymology: The name is composed of two words in Latin, “pulcher” which means beautiful, and “dormientes” = sleeping, in reference to the chain of mountains located within Tingo María National Park, above the city of Tingo Maria, locally known as Sleeping Beauty (Bella Durmiente), because it looks like a sleeping reclined woman (Figure 6A).

Resumen: Describimos una nueva especie de rana de la familia Craugastoridae de los bosques premontanos de los Andes centrales peruanos, los especímenes fueron encontrados entre los 1000 – 1700 metros de elevación. Esta especie es similar en apariencia a muchas especies de Pristimantis, sin embargo es facilmente distinguible por tener ingles, superficie posterior de los muslos y de la tibia rojo brillante. La nueva especie es conocida solo de dos localidades en la Región Huánuco, ambas separadas por alrededor de 27 km.
