Abstract

Nearly 700 species belong to Strabomantidae, a family of terrestrial-breeding, small to medium sized frogs. Of these, 516 are of the genus Pristimantis. A series of frogs collected during an expedition in a montane forest between 2843 and 3013 m elevation in the Region Lambayeque contained a new species of frog of the genus Pristimantis. This frog has female snout–vent lengths (= SVL) between 24.2–26.1 mm (n = 4) and male SVL between 17.2–18.7 mm (n = 2), and a coloration from pale brown to dark brown. It differs from its congeners by having males without vocal slits and nuptial pads, ulnar tubercles fused to a ridge, and fingers and toes with narrowly rounded discs. The new species is morphologically most similar to Pristimantis chimu, from which it differs by lacking a cranial crest and tarsal tubercles, and genetically most similar to P. simonsii and P. cryophilius.
