We describe a new species of Pristimantis from southern Ecuador, province of Zamora Chinchipe. The new species is closely related to an undescribed species of Pristimantis from Reserva Tapichalaca, Ecuador and with species of a clade historically assigned to the P. unistrigatus species group, such as P. parvillus, P. luteolateralis, P. walkeri, among others. The new species of Pristimantis is a miniaturized new frog (females 17.1±1.1 mm; males 13.2±0.9 mm), characterized by the presence of “› ‹”-shaped scapular folds, with two subconical tubercles on the medial and posterior regions of folds; tympanic membrane and tympanic annulus present but not externally visible; a prominent rostral papilla present; upper eyelid with one elongated conical tubercle; a conical tubercle on heels; groin with orange or yellow spots. The new species of Pristimantis is distributed in a restricted area in the Cordillera del Condor, a highly-diverse mountain range threatened by multiple anthropogenic activities. We recommend assigning the new species to the Endangered IUCN threatened category because it is only known from three nearby localities within mining concessions.
