Description
40-60 mm. Tympanum rather indistinct, about 1/2 of eye diameter. Tibiotarsal articulation can reach the tympanum. Finger 2 as long as finger 4. Skin on the back smooth or slightly granular. Back brown with variable pattern. Venter yellowish, with dark markings on the throat, sometimes also on the venter. Ventral surface of hindlimbs with whitish ocellae. Yellow ocellae can be present in the inguinal region. The throat of males is dark (Glaw and Vences 2007).

Similar species: R. laevipes has longer hindlimbs (Glaw and Vences 2007).

Occurs in Ambolokopatrika, Ampasinambo, Andasibe, Ankazobe, Chaines Anosyennes, Ivohibe, Malahelo, Mananara, Manantantely, Mandena, Sainte Luce, Tampolo, Tolagnaro, Torotorofotsy, Tsararano, Tsianovoha (Glaw and Vences 2007) at 100-1500m asl (Nussbaum et. al 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Usually found in burrows, under fallen wood or in leaf litter of primary or secondary forest. Vocalizations were heard during the day immediately after heavy rainfalls in the rainy season, but also in the dry season (September) (Glaw and Vences 2007).

Calls: Single notes were emitted with rather long intervals from burrows in the forest floor (Glaw and Vences 2007).

Trends and Threats
Species is listed as least concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. Though it occurs in many protected areas, its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing, fire and expanding human settlements (Nussbaum et. al 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
