A New Narrow-Toed Frog from Andean Ecuador (Leptodactylidae: Eleutherodactylus)

Resumen

Eleutherodactylus elassodiscus sp. nov. is found at intermediate elevations (1700-2600 m) on the northern Amazonian slopes of the Ecuadorian Andes. The species is distinctive in having non-dilated digital pads, the thumb longer than the second finger, and smooth skin on the venter. Its closest ally is probably E. nigrovittatus. E. elassodiscus is structurally intermediate between the predominantly tropical lowland E. binotatus group and some elements of the Andean genus Niceforonia (e.g. N. flavomaculata).
