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.
Habitat and Ecology
It occurs in leaf-litter of the rainforest and also disturbed habitats. It reproduces in backwaters of rapidly flowing streams and temporary pools.
It is abundant in some areas and uncommon in others.
Deforestation for agricultural crops and timber extraction are threats facing this species.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
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.
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).
