Scientists know it from the type locality: between 200 and 600 meters above sea level on the Araucaria plateau in Rio Grande do Sul.

[1][3] The adult male frog measures 40.7 to 49.9 mm long in snout-vent length.

It has a wide stripe bordered in from snout to groin down each side of its body, and yellow spots on its flanks.

[4] This frog is a strict forest dweller, found near permanent bodies of water, such as streams and pools with rocky bottoms.

Scientists recorded one clutch containing 200 eggs in the group but had some difficulty collecting living tadpoles.
