Gephyromantis ambohitra (Vences & Glaw 2001)

M 34-37 mm, F 32-39 mm. Dorsally less granular than G. asper and G. spinifer. Inner and outer dorsolateral ridges usually present. Small heel spines. Two often indistinct and longitudinal interocular tubercles. Colouration very variable.

Manongarivo, Montagne d’Ambre (Glaw and Vences 2007). This species has been observed at an elevational range between 500-1200 m asl in pristine rainforest only (Raxworthy and Vences 2008).

Habits: Males call at night from bushes, 0.5-1.5 m above the ground, in or near rainforest, usually close to streams. Generalized free swimming tadpoles in small streams (Glaw and Vences 2007). Calls: A slow series of about 15 unharmonious notes (Glaw and Vences 2007).

This species is listed as vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in northern Madagascar. It has a very fragmented distribution but occurs within several protected areas: the Parc National de Montagne d'Ambre, the Réserve Naturelle Intégrale du Tsaratanana, and the Réserve Spéciale de Manongarivo. A major threat is habitat loss, due to expanding subsistence agriculture, logging, charcoal manufacture, increased grazing, invasion and spread of eucalyptus, and expanding human settlement (Raxworthy and Vences 2008).
