|Scientific Name:||Mantidactylus biporus|
|Species Authority:||(Boulenger, 1889)|
Mantidactylus brauni Ahl, 1929
Rana bipora Boulenger, 1889
|Taxonomic Notes:||This species is probably a complex of at least five cryptic species (M. Vences and F. Andreone pers. comm.). The species Mantidactylus tricinctus was recently removed from the synonymy of M. biporus by Glaw and Vences (1999).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Vallan, D. & Glaw, F.|
|Reviewer(s):||Stuart, S.N., Chanson, J.S. & Cox, N.A.|
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This is a widely distributed species in northern and eastern Madagascar, with one record in central Madagascar. Two isolated records from west central and south-central Madagascar need to be confirmed. It occurs from sea level up to 1,600m asl.|

|Population:||It is a locally common species.|
|Habitat and Ecology:||It is a streamside species in rainforest, including degraded forest, and open areas adjacent to forest. It is often associated with wetlands, bogs, stagnant water, and seeps, but not fast-flowing streams. It breeds in permanent and temporary pools and in slow-moving water. Knoll et al. (2007) collected one of the benthic larvae "from a puddle beside a footpath on muddy ground".|
|Major Threat(s):||Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements.|
|Conservation Actions:||It occurs in numerous protected areas throughout the eastern rainforest belt.|
