M 33-38 mm. Tibiotarsal articulation can reach the nostril. Hand without webbing, foot webbing 1(1), 2i(1), 2e(0.5), 3i(1.25), 3e(?), 4i/e(1.5), 5(1). Terminal discs of fingers and toes moderately enlarged. Dorsal skin slightly granular. Colouration dorsally rather uniformly brown, a distinct white band along the flanks. Males with a weakly distensible single subgular vocal sac and with femoral glands (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Occurs in Andampy (Tsaratanana), Andavaka, Andranomamelona, Benavony, Manongarivo, Montagne d’Ambre (Glaw and Vences 2007) at 200-1150 m asl (Raxworthy and Glaw 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Found along streams in northern and north-western Madagascar, often in syntopy with at least one other representative of Ochthomantis (Glaw and Vences 2007).
Calls: A series of 2-9 short pulsed notes (Glaw and Vences 2007).
Trends and Threats
This species is listed as least concern because of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. Though it occurs in protected areas, its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements (Raxworthy and Glaw 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
