M 22-24 mm, F 24-27 mm. Dorsum moderately granular, head less broad than in other members of the subgenus Laurentomantis. Ventrally grey without red colour. A yellow vertebral stripe on the posterior dorsum. No tibial gland (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ilampy, Marojejy, Masoala, Tsararano (Glaw and Vences 2007). It occurs between 400-800 m asl in pristine rainforest, often but not always close to small streams (Stuart et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night in rainforest from perches 5-50 cm above the ground, often close to streams (Glaw and Vences 2007).
Calls: Unharmonious notes, each consisting of 15-39 widely spaced pulses (Glaw and Vences 2007).
Trends and Threats
Vulnerable; this species is considered abundant but decreasing. It is found in two protected areas: Parc National de Marojejy and Parc National de Masoala. It requires pristine rainforest. The main threat is habitat loss due to subsistence agriculture and grazing, logging, charcoal manufacture, invasion and spread of eucalyptus, and expanding human settlement (Stuart 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
