Scientific Name: Rhinella crucifer
Species Authority: (Wied-Neuwied, 1821)
Bufo crucifer Wied-Neuwied, 1821
Taxonomic Notes: Records of this species from Uruguay are in error. It has recently been shown to be a complex of more than one species, and R. abei, R. henseli, R. ornata, and R. pombali recognized (Baldissera et al., 2004).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Lucy Aquino, Axel Kwet, Magno Vicente Segalla, Diego Baldo
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species occurs in the Atlantic Forest of northeastern Brazil, at 0-900m asl. This species does not occur in Uruguay. Records from Misiones and northwestern Corrientes, Argentina, probably refer to B. ornatus. Records from eastern Paraguay remain unresolved, but are unlikely to refer to B. crucifer.
