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).
Habitat and Ecology
The species has been recorded along creeks and in quiet pools along small streams on the slopes of the tepui (Barrio-Amorós, 2006). It is not known if the species can persist in disturbed areas. The breeding biology of the species has not been recorded, but it is presumed to undergo larval development.
The species is known only from the type series.
Barrio-Amorós (2006) considers that the species is potentially threatened by natural or artificial catastrophes within its presumed restricted distribution.
Aprada tepui is found within the boundaries of Canaima National Park (C. (Barrio-Amorós, pers. comm. 2008).
Red List Status
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.
Anomaloglossus breweri can be distinguished from other similar species by a combination of morphological characters (Barrio-Amorós, 2006).
