Description
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.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname
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).
