Ambatovaky, Folohy, Mananara, Masoala, Tampolo.
Similar species: In M. horridus and M. ventrimaculatus the tibiotarsal articulation does not reach beyond tip of snout. M. webbi has webbed feet.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ambatovaky, Folohy, Mananara, Masoala, Tampolo. Observed at elevations from sea level to 1500m in pristine rainforest, usually on leaves of low vegetation (Glaw and Vallan 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: The habits and calls of typical G. malagasius from low elevations along the east coast are unknown. Information previously assigned to G. malagasius in fact refers to the following species which is now known to be genetically distinct from east coast populations.
Call (from Andasibe): A single, long, pulsed note. Note duration is 920-1440 ms, one note consists of 26 pulses, pulse repetition rate is 28/s. Calls are regularly repeated after intervals of 750-800 ms (call repetition rate 30/min). Frequency is 2.5-4.5 kHz. Calls from Ankeniheny (23.5°C) are similar: Call repetition rate 26-30/min, pulses per note 18, intervals between pulses 30-80 ms, pulse repetition rate 21/s. Calls from Marojezy are somewhat different: Call repetition rate is lower (15/min), note duration shorter (460 ms), intervals between pulses shorter (21-23 ms), pulse repetition rate higher (42/s; about 20 pulses per note); rarely a very long call was heard (call duration 2000 ms, consisting of about 75 pulses); frequency is 3-4.5 kHz.
Trends and Threats
It occurs in several protected areas (Glaw and Vallan 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
