Abstract

There are currently 586 species of Pristimantis distributed from Honduras, south to Bolivia, and then eastward across Brazil. Peru has 147 documented species of these terrestrial breeding frogs. One of them is Pristimantis kiruhampatu which was described based on 18 specimens from Vista Alegre, Rodriguez de Mendoza Province, Amazonas Region, Peru at 2577 meters above sea level. The type series included 4 adult females with snout-vent lengths of 19.5‒23.5 mm and 14 adult males 13.0‒17.3 mm. Pristimantis kiruhampatu is distinguishable by a \/-shaped scapular and a sacral transverse ridge, prominent conical tubercles along the lower jaw, upper eyelid with one enlarged tubercle and axillae, groin, and hidden surfaces of hindlimbs are cherry with white flecks. We have seven specimens collected ca. 75 km (airline) northwest from the type locality of P. kiruhampatu. Diagnostic comparisons between our taxon and P. kiruhampatu reveal that our specimens do not display a number of morphological features that are characteristic of P. kiruhampatu such as a \/-shaped scapular and sacral transverse ridge, conical tubercles along the lower jaw, and a tarsal fold. We analyze the differences and similarities in morphological features, and the distributional gap to determine if our series of Pristimantis is a novel species or a variation of P. kiruhampatu.
