Pristimantis ernesti is a species of frog in the family Strabomantidae. It is endemic to the summit of Sumaco, a volcano in the Napo Province, Ecuador.[2][3] Its common name is Ernest's robber frog.[2] It is named after Dr. Ernst Williams, a friend and colleague of the scientist that described the species. It is a little studied species.[3]
Males measure about 29 mm (1.1 in) in snout–vent length. Female size is unknown. The dorsum is coffee-coloured with dark gray markings, including a "W" mark on its upper back. Dorsal skin is glandular with prominent dorsolateral ridges.[3]
Its natural habitat is grassland and bushland on the summit of Sumaco.[1][3] Herpetological sources cite the altitude as being about 1,900 m (6,200 ft),[1][2][3] although other sources give maximum elevation of 3,732 m (12,244 ft) to this mountain.[4] The volcano is in the Sumaco Napo-Galeras National Park.[4] Nevertheless, being restricted to a single location, the population is vulnerable stochastic processes.[1]
