Two male specimens (DHMECN 14443-14706) with a body size of 15.77 to 19.43 mm and one female specimen (DHMECN 14707) with a body size of 19.71 mm were collected on bush leaves at 100 cm from the ground, in the montane forests of the Machay Reserve at 2430 m elevation. The external morphology and colouration pattern are somewhat similar to Pristimantis eriphus ; however, the latter has red eyes and white spots in the groin, as opposed to the yellowish spots and coppery yellow iris of the present species.
