M 21-23 mm, F 32 mm. Tibiotarsal articulation reaches at least the nostril and often beyond snout tip. Hand with some webbing, foot webbing 1(0), 2i(0.5), 2e(0), 3i(1.25), 3e(0.5), 4i/e(2), 5(0.5). Dorsal skin smooth. Dorsally green, sometimes with traces of yellow dorsolateral lines, and always with numerous, evenly spaced small red dots. Tips of fingers and toes greenish. Outer iris area turquoise, iris periphery blue (Glaw and Vences 2007).
Similar species: B. erythrodactylus differs by having red colour on the tips of fingers and toes (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
An’Ala, Andasibe, Mananara, Mantadia, Ranomafana (Vohiparara, Imaloka, Maharira forest) (Glaw and Vences 2007). It occurs at 300-900 m asl in pristine rainforest (Vences et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Males call at night from 1-3 m above the ground in the vegetation next to streams in rainforest. The call is a short, high-pitched note consisting of two, sometimes three, clicks (Glaw and Vences 2007). Breeding occurs in the streams (Vences et al. 2008)
Trends and Threats
A common, widely distributed species, but threatened by habitat loss due to increasing subsistence agriculture, logging, charcoal manufacture, invasion and spread of eucalyptus, increased grazing and expanding human settlement. Requires pristine forest. Occurs in several protected areas (Vences et al. 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Subtle changes to necessary specialized habitat
