Geographic Range [top]

Range Description:This species ranges from extreme southeastern Guinea through Liberia, Côte d’Ivoire and western Ghana, with a disjunct population in southwestern Nigeria. Records on the Guinean side of Mount Nimba were made in 2006 (A. Hillers unpubl. data). In 2010, it was found in the Yaya Classified Forest (Alépé region, southeast Côte d'Ivoire) (N.G. Kouamé pers. comm. May 2012), and in Atewa in Ghana in 2006 (N.G. Kouame pers. comm. June 2012). It has recently been confirmed in Tanoé-Ehy Swamp Forests (Kpan et al. 2014) and Yakassé-Mé village forest, southeastern Côte d'Ivoire (Kouamé et al. 2014). In Côte d'Ivoire it is found in lowland areas (500–1,000 m Asl), but it is likely to occur much lower in other parts of its range down to sea level. As such, the northern boundary of the range map follows the WWF Ecozones for Western and Eastern Guinean forests, and Nigerian lowland forest.

Population [top]

Population:This species is rare in southeastern Côte d'Ivoire and in Atewa (N.G. Kouame pers. comm. June 2012). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It is found mostly in primary rainforest, although it has been recorded in farm bush adjacent to forest (degraded forest and farmland) (Hillers and Rödel 2007) and regenerating secondary forest along an old logging road (N.L. Gonwouo pers. comm. May 2012). It is often found with Afrixalus dorsalis but separated by microhabitat preferences, with A. dorsalis using more open, exposed sites, and this species calling from dense vegetation. During breeding, the eggs are laid on leaves overhanging temporary ponds, into which the larvae fall and develop.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade:

There are no records of this species being utilized.

Threats [top]

Major Threat(s): Forest habitat throughout the region is decreasing as a result of agricultural encroachment (coffee and cacao plantations in Liberia, Côte d'Ivoire and Ghana), expanding human settlements, and logging.

Individuals from Nigeria tested positive for Bd (Imasuen et al. 2011) suggesting that chytridiomycosis could be a threat to this species, although no mortalities or ill effects have yet been observed.

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species occurs in several protected areas including the Mount Nimba World Heritage Site in Guinea, Yaya Classified Forest in southeastern Côte d'Ivoire (N.G. Kouame pers. comm. May 2012), Atewa Range Forest Reserve in Ghana (N.G. Kouame pers. comm. June 2012) and Okomu National Park in Nigeria (Imasuen et al. 2011). 

Research Needed
Research is needed for the life history of this species.
