Proceratophrys vielliardi

The adult male frog measures 39.1–41.9 mm in snout-vent length. The skin of the dorsum is light bronw in color with some red-brown on the flanks and light brown on the eyelids and on the back of the head. The belly is light brown in color. There are black-brown and light brown bands on the limbs. The iris of the eye is gold or bronze in color.

This frog has been observed next to streams in the savanna. Scientists saw the frog between 930 and 1270 meters above sea level. The frog has been reported in three protected parks: Área de Relevante Interesse Ecológico Capetinga - Taquara, Parque Estadual da Serra de Caldas Novas, and Parque Estadual de Paracatu.

The male frogs call to the female frogs in summer (November and December). The female frogs deposit eggs temporary streams and bury them in sand or mud at the bottom. The tadpoles develop in the streams.

Scientists named this frog for ornithologist Dr. Jacques Marie Edme Vielliard, who studied Brazil's birds and other fauna, including frogs.
