This species is widespread in northern and eastern Madagascar. The map is not meaningful for the same reason as for Mantidactylus grandidieri. It has been recorded at 200-1,000m asl. Records from Nosy Be probably refer to M. ulcerosus.
Habitat and Ecology
A semiaquatic species found in or near streams in forest in pristine rainforest. Its breeding is unknown, but it is probably by larval development in streams.
It is a moderately common species, being more common in the north of its range.
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements. It is collected for human consumption, and this can have a local impact on populations.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
This species is closely related to, and has been confused with, Mantidactylus grandidieri and an undescribed species from the northeast of Madagascar (F. Andreone pers. comm.). Revision of this complex is urgently needed.
