INTRODUCTION The genus Eletifherodactijlus is a prominent component in most faunas from northwestern South America. The genus is well represented in the faunas of the lowlands as well as the high An-dean paramo and pajonal (of Acosta-Solis, 1968) habitats. Such habitats gen-erally occur at elevations above 3000 m. The Andes of northern Ecuador have considerable contiguous areas at eleva-tions above 3000 m, whereas in southern Ecuador (south of the Nudo de Azuay) areas above the 3000 m contour are dis-continuous (Fig. 1). This patchiness of high montane territory continues into northern Peru, where south of the Hu-ancabamba pass the Andes again have \'ast areas of contiguous high altitude habitats which grade into the puna in southern Peru and Bolivia. The genus Eleutlwrodactylus is found in the high montane localities in Ecuador and ex-treme northern Peru, but south of Huan-cabamba, suitable habitat is meager or other frogs occupy the habitats occupied by Eleutherodacfylus at more northern localities. The eleutherodactyline fauna of northern Andean Ecuador is now rela-tively well known (at least taxonomical-ly). In contrast, that of the Andes of southern Ecuador is poorly known.
