A new species of Atelopus is described from three localities near Oxapampa between 1700 and 2200 m elevation in central Peru, representing the first record for the genus in the Department of Pasco. The new species is readily distinguished from all congeners by its small size (maximum SVL 22.1 mm in males), numerous gray coni on dorsal and lateral body surfaces, and a coloration pattern consisting of a cream dorsolateral stripe, narrow dark brown middorsal stripe, arms and legs dorsally dark brown with grayish brown reticulation, and ventral surfaces of hands and feet reddish orange. Females are unknown.
