Stefania breweri Barrio-Amorós and Fuentes, 2003 *

Holotype: MBUCV 6574 .

Type locality: “ Summit of Cerro Autana (Wahari Kuaway), near the north ridge (4°52’N, 67°27’W), 1,250 m elevation, Municipio Atures, Estado Amazonas, Venezuela.”

Distribution: Region 5. Endemic to Autana, a tepui in Estado Amazonas.

Remarks: Not seen during two expeditions to the top of Autana after the collection of the only known specimen in 1971. Autana has an extremely small surface of 1. 9 km 2, so this is one of the most geographically restricted frog species in the world. However, it is only DD by IUCN (Stuart 2006) and Rodríguez and Rojas-Suárez (2008) keep it under IUCN category VU/D2; it is not even mentioned in the last edition of the Venezuelan Red Book ( Rodriguez et al. 2015). We argue that the species (known from a single specimen, not seen during two expeditions with herpetologists in 1972 and 2001, and restricted to an area of 1. 9 km 2) should be classified CR B2a.
