Phrynobatrachus guineensis Guibé and Lamotte, 1962
The IUCN Red List (2010) categorizes this spcies as Near Threatened since although this species is still relatively widely distributed, it depends on areas of undisturbed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable (Rödel and Schiøtz, 2004).
It occurs in Taï National Park (Côte d’Ivoire) and the Mount Nimba World Heritage Site (Guinea, Liberia, Côte d’Ivoire; Rödel and Schiøtz, 2004).
This species is adversely affected by the loss of forest habitat due to agricultural development, logging and expanding human settlements. Some populations might also be affected by mining activities (Rödel and Schiøtz, 2004).
Populations of this species are believed to be decreasing (Rödel and Schiøtz, 2004).
This species occurs in the western Upper Guinea forest zone of West Africa, in Sierra Leone, southern Guinea, Liberia, and western Côte d’Ivoire (Rödel and Schiøtz, 2004).
It is restricted to the drier parts of primary rainforest up to approximately 1,000m asl., where it is an arboreal species usually found low in the trees (Rödel and Schiøtz, 2004).
It is a common species in suitable habitats (Rödel and Schiøtz, 2004).
This species deposits its few large eggs above water in small water-filled tree holes empty fruit capsules, or snail shells, making this species independent of waterbodies. They attach small numbers of single eggs above the water surface to the walls of the holes, where they develop. After approximately four days, the tadpoles drop into the water and continue their development until they leave the holes after less than a month as small froglets. The tadpole-densities in these holes are up to ten times higher than known from other species (Rödel, 1988).
