Description

Frogs of the genus Pristimantis are most diverse in northwestern South America. They are distributed from lowland rainforest to elevations of about 4000 m in the Andes. Of the 516 species currently assigned to the genus Pristimantis, 138 species occur in Peru. Herein, we present a new species of Pristimantis from the Cajamarca Region of northern Peru. The new species is known from four male and five female specimens found in high Andean grasslands hiding in the rosette of Puya fastuosa (Bromeliaceae) at 3600 m above sea level. The new species is phenotypically distinguished from its congeners by having a black dorsum with sprinkled white flecks and a dark brown groin with white spots. Furthermore, it has a snout-vent length of 23.6–27.2 mm (n = 4) in adult males and 25.6–32.8 mm (n = 5) in adult females.
