Found throughout the Reserva Florestal Adolpho Ducke in Brazil.

Life History, Abundance, Activity, and Special Behaviors
The species is terrestrial and diurnal. Adults feed mainly on termites, flies and beetles. Juveniles eat mainly collembolans and mites. Reproduction occurs between November and March, with a peak in January. Females deposit about 3-6 eggs out of water in rolled or doubled fallen leaves, where the tadpoles develop to metamorphosis. Adult males are territorial, and tend the eggs and tadpoles.

Comments

Colostethus sp. are similar, but have a continuous dark brown lateral stripe from the snout to the cloaca, forming a circle around the body, an orange-brown dorsum, and gray hind legs. Juvenile Adenomera andreae and Eleutherodactylus fenestratus lack the dark brown lateral stripe.
