Rhaebo nasicus (Werner 1903)

Holotype: MRHN I.G. 9422 reg. 1015.

Type locality: Type without locality data, restricted to “South America, probably along the Atlantic drainage” by Smith and Laurent (1950) .

Distribution: Region 5. Known from eastern Venezuela and northwestern Guyana. In Venezuela it was previously known only from the La Escalera Region of Bolívar State (Barrio-Amorós 2009). Occurrence reported here from 7. 1 km N Kavanayen (EBRG 5581, 5583, 5588, 5763), and from the Churún River, near the base of Angel Falls, on the northern side of Auyán-tepui (MHNLS 20429).

Remarks: See remarks under Rhaebo ceratophrys . Barrio-Amorós (2009) and Barrio-Amorós and Duellman (2009) were reluctant to recognize nasicus as a member of Rhaebo , but thought it should be placed in Rhinella based on external characteristics. Pramuk (2006) showed the relationship of nasicus as being the most basal in the Bufo guttatus species group (now Rhaebo ).
