M 23-24 mm. Morphologically similar to the sympatric G. blanci. Weakly expressed dorsolateral ridges present. Colouration variable. A more or less continuous whitish stripe along the upper lip (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Inside Ranomafana National Park at Mount Maharira (summit), and just outside of the park at sites west of Vohiparara (Glaw and Vences 2007). It has been reported from 1,000-1,350 m asl (Vences and Andreone 2008). The mountain peak habitat has large bare surfaces of granitic rock, with heath, bushland and patches of rainforest surrounding it (Vences and Andreone 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Males were found calling during the day in dense fern and ericoid vegetation close to the summit of Mount Maharira in Ranomafana National Park (Glaw and Vences 2007). Calls are made from perches in the vegetation, 10 cm to 1.5 m above ground (Vences and Andreone 2008). Breeding is not known but this species may be a direct developer (Vences and Andreone 2008).
Calls: The call is very distinct, and consists of a series of note groups, each of which is composed of 2-4 rapidly repeated melodious notes (Glaw and Vences 2007).
Trends and Threats
Occurs in a protected area, the Parc National de Ranomafana. Most common at the summit of Mt. Maharira, but rare outside of Ranomafana (Vences and Andreone 2008). Outside the park its habitat is threatened by agriculture (Vences and Andreone 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Intensified agriculture or grazing
