M 26-32 mm, F 37 mm. Tibiotarsal articulation reaches at least the eye, sometimes beyond snout tip. Hand with some webbing, foot webbing 1(0), 2i(1), 2e(0), 3i(1), 3e(0), 4i/e(1.5), 5(0.5). Dorsal skin smooth. Dorsally beige, orange or reddish brown, with numerous small reddish spots and a large dark hourglass marking. Ventrally whitish. Males with indistinct nuptial pads and a moderately distensible single subgular vocal sac.
Similar species: The colour of B. pyrrhus allows a relatively unambiguous identification. The species most closely related is B. haematopus which can be distinguished by its red colour on limbs.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Central-eastern Madagascar: An’Ala, Andasibe, Ankeniheny, Mananara, Manombo, Mantadia, near Ifanadiana, Vevembe. Observed between 450-915 m asl. Found in rainforest and secondary vegetation along streams, ditches and swamps with slowly flowing water (Andreone et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night from perches 1-2 m high in the vegetation. Eggs are of blackish colour.
Calls: A series of 12-17 unharmonious notes of high-pitched “metallic” sound, getting more intense towards the end of the call. The call is very typical and can only be mistaken with those of B. haematopus and Guibemantis liber.
Trends and Threats
Locally common but decreasing. Can tolerate degraded habitat if it is near pristine rainforest, but has not been found in open areas. Habitat is being lost due to subsistence agriculture, grazing, logging, charcoal manufacture, and expanding human settlement. This species is known to occur in the Parc National de Ranomafana, the Réserve Spéciale d’Ambatovaky, and is thought likely to be present in other protected areas as well (Andreone 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
