Males 26-29 mm, females 31-39 mm. The body is flattened. The dorsum consists of a net-like pattern of green on a brown background. Most of the ventral surface is white, but the hands, feet, and posterior surface of the belly are red.

Similar species: Dendrophryniscus minutus is the only other species with a body form similar to that of A. spumarius, but it does not have a green net-like pattern on the dorsum, and its ventral surface is black at the front and spotted black on the belly.

General distribution: Amazonian basin of Brazil, Peru and Ecuador, and in Guyana, Surinam, and French Guiana.

Distribution in the Reserva Florestal Adolpho Ducke: The species occurs only in the eastern part of the reserve, where it can be found easily along the banks of streams that drain into Igarapé Tinga, Igarapé Uberê, and Igarapé Ipiranga.

Life History, Abundance, Activity, and Special Behaviors
The species is terrestrial and diurnal, and is most commonly found on leaf litter or fallen tree trunks near streams. Reproduction occurs throughout the year. The eggs are deposited in gelatinous strings in streams or pools near streams. Tadpoles, which have a large oral disc, develop to metamorphosis in the water.

Trends and Threats
This species has not been reported from Ecuador since November 1994. It is also thought to have declined in Peru. In the rest of its range it seems to be locally abundant. It generally occurs below the altitude where chytridiomycosis shows the most effect on Atelopus species (Azevedo-Ramos et al. 2008).
