Description
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.
Habitat and conservation
Its natural habitat is grassland and bushland on the summit of Sumaco. Herpetological sources cite the altitude as being about 1,900 m (6,200 ft), although other sources give maximum elevation of 3,732 m (12,244 ft) to this mountain. The volcano is in the Sumaco Napo-Galeras National Park. Nevertheless, being restricted to a single location, the population is vulnerable stochastic processes.
