This species is known only from two localities in north-eastern Brazil: Joazeiro, in the northern part of the state of Bahia; and Cabaceiras, in the state of Paraiba. It presumably occurs more widely, including in the intervening area between these two localities. All records have been from about 200m asl.
Habitat and Ecology
It is a species of dry Caatinga savannah, which presumably breeds in temporary ponds by larval development.
There is no information on this species' population status, since it is known from only a few specimens. Since it cannot be easily distinguished morphologically, it is probably under-recorded.
There is very little information on threats to this species, but it is possibly affected by agricultural expansion, and especially by over-grazing by livestock. It is possibly also present in the national and international pet trade.
It is not known from any protected areas.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity, extent of occurrence, status and ecological requirements.
This species is an octoploid species most closely related to Ceratophrys ornata according to Mercedal (1986), but it is genetically distinct.
