Adults 75-108 mm. Similar to M. guttulatus but usually with a less granular skin and smaller discs on fingers and toes. Some specimens can appear very granular.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ambalamarina, Ambalamarovandana, Ambana, Ambatolampy, Ambatovory, Ambohitantely, Ambohitsara, Ampasy, Analamazoatra, Andasibe, Andohariana, Andringitra (Iantara river, Sahavatoy river), Antananda, Betampona, Chaines Anosyennes, Isaka-Ivondro, Ivohibe, Manantantely, Mangevo (Ranomafana), Manjakatompo, Mantasoa, Midongy, Moramanga, Moramanga-Niagarakely, Pic St. Louis, near Ifanadiana, Sandrangato, Torotorofotsy 1, Vevembe, Vohidrazana, Vondrozo. Assignment of many localities is tentative. It occurs between sea level to 1,500m asl around streams of pristine rainforest (Andreone and Raxworthy 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: As in M. guttulatus. Tadpoles with unusual, papillae-rich mouthparts have been found in a stream in Ranomafana National Park, but seem to be very rare; possibly their development takes place partly at hidden sites.
Breeding is unknown, but larval development probably takes place in streams (Andreone and Raxworthy 2008).
Trends and Threats
It occurs in many protected areas (Andreone and Raxworthy 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Intentional mortality (over-harvesting, pet trade or collecting)
