Year Published: 2008
Date Assessed: 2008-01-01

Listed as Vulnerable because its area of occupancy is less than 20 km2, it is only known from one locality, and it is considered to be sensitive to potential natural or artificial catastrophes.

Geographic Range [top]

Range Description: Anomaloglossus breweri is known only from Aprada tepui, Bolívar state, Venezuela (Barrio-Amorós, 2006). The type series was collected at the entry to the vast Cueva del Fantasma (05 27’N, 62 27’W, 660 masl), a collapsed steep gorge on the northwestern slope of the tepui (Barrio-Amorós, 2006). The species seems unlikely to be restricted to the Cueva del Fantasma, but is possibly endemic to the Aprada tepui or more widely to the Gran Sabana region (Barrio-Amorós, 2006).
