Abstract
The genus Pristimantis contains 587 species which are distributed from eastern Honduras, south through Bolivia and east through Brazil. The high species diversity, wide distributional range, high phenotypic variation, and presence of cryptic species make them oftentimes difficult to classify. There are 147 known species of Pristimantis within Peru. One of them is P. bipunctatus, a species that is currently not well known. This species was originally described in 2005 based on a single adult female specimen obtained from the Cordillera Yanachaga in central Peru at 2120 meters above sea level. A series of 15 specimens collected by Lehr and colleagues between 2011 and 2014 in central Peru between 1550 and 2230 m elevation above sea level is the basis for this project. We present new distributional records, phenotypic variation (snout-vent lengths, morphological characters, and coloration variation) for adult males and females. We also highlight a previously unrecognized character, two minute snout tubercles.
