M 24-25 mm. F 33 mm. Tibiotarsal articulation reaches at least between eye and nostril and sometimes beyond snout tip. Hand with some webbing, foot webbing 1(0), 2i(0), 2e(0), 3i(1), 3e(0-0.5), 4i/e(1), 5(0). 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 reddish, especially in females. Outer iris area turquoise to blue, iris periphery blue.
Similar species: B. tasymena differs by lacking red colour on the tips of fingers and toes, and by advertisement call structure.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Mahajeby, Mandraka. It occurs between 1,000-1,100m asl in rainforest, including disturbed sites next to rainforest (Glaw et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Males have been observed calling at night from 1-3 m above the ground in the vegetation next to a large, fast-flowing stream at Mandraka.
Calls: A note consisting of 4-7, sometimes up to 14 click pulses.
Breeding takes place in streams (Glaw et al. 2008).
Trends and Threats
Least Concern: wide distribution, tolerance of habitat modification, and large population. It occurs in the Ranomafana and Mantadia National Parks (Glaw 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
