Two New Species of Centrolenid Frogs from the Amazonian Slope of the Cordillera Oriental, Ecuador

Resumen

Two new species of centrolenid frogs are described from the Amazonian slopes of the Cordillera Oriental of the Andes in Provincia Morona-Santiago, Ecuador. The first species is a member of the Centrolene prosoblepon group and is distinguished from all other members of the group by having a lateral row of large enameled tubercles that extends from below the eye to just posterior to the insertion of the arm. The condition of the humerus was compared with that of other species of the C. prosoblepon group from Ecuador and was found to be most similar to the condition of C. audax. The second species is a member of the Cochranella ocellata group and is distinguished from all other members of the group by possessing white visceral pigmentation on the esophagus, a first finger shorter than second, and lacking vomerine teeth
