Two new species of Atelopus (harlequin frogs) are described from the Andes of northern Peru, one from the northern Cordillera de Huancabamba (Departamento de Piura), 2,950 m elevation, and the other from an inter-Andean valley of the upper Marañon basin, Cordillera Central (Departamento de La Libertad), 2,620 m elevation. We also suggest the possible link between infection by the chytrid fungus and mortality of harlequin frogs in the upper Marañon basin in 999.
