Characteristics: Medium-size species measuring about 6.0cm in length. This frog's body is disc-shaped, its skin is smooth, its head is large, and snout short. The coloring is usually a burst of gray, and may vary to red. The back portion of its body has two black glands surrounded by white rings ("eye spots", resembling a big pair of eyes). When threatened, it hides its head between its front legs, inflates its body, lifts its back and exposes its glands. If this attempt fails, when biting it the predator will come into contact with the poison glands, causing it to release the frog.

Distribution: This species is distributed throughout Midwestern and Southeastern Brazil, in the states of Mato Grosso do Sul, Goiás, São Paulo, and Minas Gerais, all the way to Eastern Paraguay and Eastern Bolivia.

Habitat: Open formations, in savannas, scrublands, forest edges, grasslands, lakes, ponds, rivers and lentic streams, and it may also be found in forested regions.
