Generally a rather small and stout Mantella, although single females can become relatively large. SVL usually 19-23 mm (females exceptionally up to 30 mm). Dorsally uniform yellow-orange or red-orange, without translucent shading, and with a black spot covering the tympanum and a little black pigment around the nostril. Bright red flashmarks present. Iris nearly uniformly black, only a little light pigment in its upper part. Ventrally uniform, similar to dorsal surface but generally somewhat lighter. Area of femoral glands often speckled with blackish. Tibia bright red (Glaw and Vences 2007). It may be a colour variant of M. crocea (Vences and Nussbaum 2008).
Similar species: M. crocea (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Typical specimens from Fierenana. Intermediate populations with M. crocea from several sites, e.g., Andriabe and Savakoanina. It occurs between 900-1,000 m asl in gallery forest around large swamps and seasonally flooded forest, but not outside forest (Vences and Nussbaum 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Apparently similar to that of M. aurantiaca and M. crocea. Active during the day (Glaw and Vences 2007).
Calls: Irregular series of short chirping notes (Glaw and Vences 2007).
Breeding is similar to other Mantella. Eggs are laid on land and the larvae are washed into swamps by rain. It is very seasonal in its breeding, and hard to find when it is not breeding (Vences and Nussbaum 2008).
Trends and Threats
It has a small, severely fragmented distribution. It is not known from any protected areas, so that protection of remaining habitat should be made a top priority. Monitoring should be done, and any trade should be regulated (Vences and Nussbaum 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Intentional mortality (over-harvesting, pet trade or collecting)
The validity of this taxon is very dubious. A reliable distinction from M. crocea is not possible, neither by morphology, colouration nor by genetics (Glaw and Vences 2007).
