M 36-43 mm. Tibiotarsal articulation reaches at least the eye, sometimes beyond snout tip (Glaw and Vences 2007). Hand with some webbing, foot webbing 1(0), 2i(1), 2e(0), 3i(1), 3e(0), 4i/e(1.25-1.5), 5(0) (Glaw and Vences 2007). Dorsal skin with a network of fine dermal reticulations (Glaw and Vences 2007). Distinct spines on elbow and heel (Glaw and Vences 2007). Colour typically rather uniform light (Glaw and Vences 2007) to dark brown (Vences et al. 2005). Legs and arms are gray-brown with darker brown banding (Vences et al. 2005). Venter white with dark brown speckling on throat, chest and belly (Vences et al. 2005). Distinct whitish tubercles in the cloacal region (Vences et al. 2005). Iris light tan with brown speckling near the pupil, and a turquoise periphery. The outer iris area in its upper part is reddish except in specimens from Marojejy, which are genetically differentiated and have a brown eye colouration (Glaw and Vences 2007). Males have nuptial pads (Vences et al. 2005).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Tsaratanana Massif (Antsahamanara campsite, at 688 m asl ), Manongarivo Massif (1000 m asl), Marojejy Massif (700 m asl), and the Anjanaharibe Sud Special Reserve (Glaw and Vences 2007; Vences et al. 2008).
Life History, Abundance, Activity, and Special Behaviors
Males call at night from bushes and trees 2-3 m above the ground along small streams in rainforest. The calls consist of two types of unharmonious notes, a longer, isolated note and a series of about ten short notes (Glaw and Vences 2007). Breeds in streams (Vences et al. 2005)
Trends and Threats
Reduced distribution area (Glaw and Vences 2007). Populations may be fragmented (Vences et al. 2005). Occurs within at least one protected area, the Anjanaharibe Sud Special Reserve (Vences et al. 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
