Overview

Comprehensive Description

Description

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).

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).

Threats

Major Threats
Its currently known sites are within protected areas, but it probably occurs in other unprotected sites which are likely to be subject to forest loss.

Life History, Abundance, Activity, and Special Behaviors

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).
