Red List Status
Data Deficient (DD)
Listed as Data Deficient because it has only recently being discovered and there is still very little information on its extent of occurrence, ecology and population trends.
This species is morphologically similar to Pristimantis cantitans, but it is of smaller size and different colouration. It is similar in size and morphology to the sympatric P. memorans, but it is distinguished by lacking the W-shaped scapular mark.
