M 20-21 mm, F 21 mm. Weakly expressed dorsolateral ridges. Dorsal colour usually light brown. A continuous whitish or yellowish stripe along the upper lip. Lower lip ventrally with distinct alternating brown-white pattern. Males with a bilobate subgular vocal sac which is laterally blackish (Glaw and Vences 2007).
Similar species: Morphologically very similar to G. eiselti and G. thelenae, but does not appear to be closely related to these species (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ranomafana National Park (Ambatolahy, Maharira forest, Ranomafanakely, Vohiparara), Vevembe (Glaw and Vences 2007). It occurs at elevations from 650-1,050 m asl, in secondary and degraded forest, and low secondary vegetation, rarely in primary forest (Glaw and Cadle 2008). Usually seen on low vegetation far away from water (Glaw and Cadle 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Males are commonly heard calling at higher elevations in Ranomafana National Park, during the day, from positions on the forest floor, not concentrated at water bodies. Large eggs belonging to this species have been found in the leaf litter, suggesting direct development (Glaw and Vences 2007).
Calls: A slow series of about 40 short melodious notes (Glaw and Vences 2007).
Trends and Threats
Found within one protected area, the Parc National de Ranomafana. Adaptable and unlikely to be threatened by deforestation (Glaw and Cadle 2008).
