Two new Centrolenella are described, C. azulae from the Cordillera Azul of Peru, and C. puyoensis from the Amazonian slopes of the Ecuadorian Andes. Centrolenella azulae is distinguished by its moderately large size, the presence of vomerine teeth, a snout truncate in dorsal view and slightly protruding in profile, a color pattern in preservative of very diffuse lavender with small colorless spots, basal webbing on the outer fingers, and a low ulnar fold. Centrolenella puyoensis is distinguished by its moderately large size, a snout truncate in dorsal view and rounded in profile, a color pattern in preservative of purplish-gray with large cream spots, a tympanum that is three-fourths exposed, and intricate anal ornamentation. Both new species are closely related to the Peruvian C. mariae, and together the three species form the C. mariae group, definable on a number of shared, derived characters. A hypothesis of relationships within the mariae group is presented, postulating puyoensis as the most primitive and azulae as the most derived of the trio.
