Centrolene condor sp. nov.

A new species of glassfrog from the elfin forests of the Cordillera del Cóndor, southeastern Ecuador (Anura: Centrolenidae)

Abstract.-- We describe a new species of glassfrog of the genus Centrolene (Amphibia: Anura: Athesphatanura: Centrolenidae) that inhabits the elfin forests of the Cordillera del Cóndor, an isolated mountain chain separated from the Cordillera Oriental of the Andes by the valley of the River Zamora. This new species is characterized by having vomerine teeth; a subacuminated snout in dorsal view and strongly sloping in profile; a tympanic annulus rather indistinct; shagreened dorsal skin with low warts and abundant spicules; a subcloacal area granular with several enameled warts; humeral spines in adult males; enameled ulnar folds; enameled metatarsal folds; a row of distinct enameled tubercles along the outer tarsal edges; and a green dorsum in life with abundant light and dark flecks. This taxon is the most distinct of a phenetic-set of species that includes Centrolene altitudinale, C. buckleyi, C. heloderma, C. hesperium, C. lemniscatum, and C. venezuelense.

Centrolene durrellorum sp. nov.

A new species of glassfrog of the genus Centrolene from the foothills of Cordillera Oriental of Ecuador (Anura: Centrolenidae)

Abstract.--A new species of frog of the family Centrolenidae is described from Ecuador, Centrolene durrellorum sp. nov. This new taxon is the first species of the genus Centrolene known to inhabit the central and southern foothills of the Cordillera Oriental of Ecuador. The new species is diagnosed from other centrolenid taxa by its moderate body size (25.7–26.1 mm adult males), uniform coloration (green in life, pale lavender in preservative), rounded snout in dorsal and lateral views, presence of medium-sized straight humeral spines with a moderate spiny point in adult males and absence of guanophores on the visceral peritonea.
