Distribution

Distribution and Habitat

Mangevo (Ranomafana), Manombo, near Tolongoina, Vevembe, and some additional unnamed localities. It occurs between 60-629m asl in degraded rainforest, including very tiny patches. It is not found in open areas or littoral forest on a sandy substrate (Cadle and Raxworthy 2008).

Conservation

Life History, Abundance, Activity, and Special Behaviors

Habits: Known from several, often fragmented low-altitude rainforest areas, sometimes associated with swamps. Active during the day on the ground.

Calls: A short trill, different from other Mantella calls, and reminding a cricket. One single note that is a short trill consisting of 2-8 clicks. Click duration 11-19 ms, duration of intervals 8-15 ms. Frequency is between 4.8 and 5.7 kHz. Calls are repeated after irregular intervals. Eggs and tadpoles: Unknown.

Threats

Life History, Abundance, Activity, and Special Behaviors

Endangered: area of occupancy is probably less than 500km2, its distribution is severely fragmented, and the extent of its forest habitat in east-central Madagascar is declining, and the number of mature individuals might also be declining through over-exploitation. It is found in the Manombo Special Reserve and Parc National de Ranomafana. There is a need for trade in this species to be carefully regulated (Cadle and Raxworthy 2008).
