F 39 mm. Only recently resurrected from the synonymy of M. brevipalmatus which is closely related and morphologically very similar. M. delormei has a more distinct colour border between flanks and dorsum, and in general a more uniformly brownish colour with a dark median area on the dorsum, and a more yellowish colour on the ventral side (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Andringitra Massif, Imaitso forest; Maharira forest in Ranomafana National Park (Glaw and Vences 2007). Found at mid- to high-elevation, 1300-1800 m asl. Not found in more open forested habitat (Stuart et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Along streams in forests of relatively high elevations. Unlike M. brevipalmatus, this species has not been found above the tree line although it occurs at Andringitra where such habitat is available. Males call during the day and at dusk from the ground along the streams (Glaw and Vences 2007). Stream-breeding (Stuart et al. 2008).
Calls: A rapid series of short notes of slightly melodious appearance, similar to the call of M. brevipalmatus (Glaw and Vences 2007).
Trends and Threats
Rare and decreasing. It occurs in two protected areas, Andringitra National Park and Ranomafana National Park. It probably occurs outside those protected areas, making the major threat likely to be habitat loss due to deforestation (Stuart et al. 2008).
Possible reasons for amphibian decline
Habitat modification from deforestation, or logging related activities
