A toad found in the South American Cerrado, a landscape that includes open grasslands and savanna.
The ridges above the eyes are low.
This toad can inflate its body and adopt a stiff-legged posture. An individual whose leg was seized vocalized intensely and eventually jumped away.
On the night of 9 November 2020, an individual was attacked by a larger toad of another species in a backyard in Barras, Piauí, northeastern Brazil. The attacker, Rhinella diptycha, measured 125 mm from snout to vent; the adult mirandaribeiroi measured 65 mm. The larger toad grasped its left leg.
The captured toad immediately vocalized intensely and inflated its body. The encounter lasted about two minutes, after which it adopted a stiff-legged posture and then jumped away. The observer captured it for inspection; it appeared uninjured and was released at the same location. The 2021 account documented stiff-legged behaviour for this species for the first time. The author also proposed that inflation might have helped it escape.
An extinction-risk assessment has not been added yet.
A survey conducted in eastern Maranhão, Brazil, from February 2019 to February 2020 found this species’ tadpoles in puddles up to 30 cm deep, with sparse Cerrado vegetation along the margins. The 2023 paper identified vegetation clearance, conversion to pasture and fires in the study region as conservation concerns. Retaining shallow waters and surrounding vegetation, and monitoring larval habitats, are possible measures for this species.
