At the type locality, Tandayapa, Pichincha Province, numerous follow-up surveys after 1970 failed to record the species suggesting that the population is extinct. The rediscovery of A. olallai took place in 2012 at Río Manduriacu, Imbabura Province, Ecuador. Two surveys suggest that a healthy population of A. olallai survives at the site, with observations of froglets, juveniles, and adults across numerous stream systems. However, the extent of known occupancy of the population is small (<1 km2). Further data are presented to update knowledge of the distribution, ontogeny, morphology, and conservation status of the species. The population at Río Manduriacu is surrounded by logging, mining, and hydroelectric developments that could compromise its future survival. There is an urgent need to establish a monitoring program and to protect its remaining population and habitat in the region. Key words.

Perch height for each individual was measured using a marked meter stick and SVL measurements were taken using dial calipers. Climate information was recorded us- ing a handheld Kestrel 3500 Weather Meter. Individual toads were only handled when necessary, and always with use of latex gloves to prevent transferring pathogens such as amphibian chytrid fungus (Batrachochytrium dendrobatidis). Results and Discussion During the first survey of Manduriacu on 18 November 2012, two adult A. olallai were encountered perched on leaves overhanging a small running stream. Elevation of the observation site was 1,253 m, and perch heights Fig. 1. Known records of Andinophryne olallai in northwest of the individuals were 1.5 m and 2.0 m above ground.
